-<h2 id="support">Support</h2>
-<p>The Solr Community provides user support for free through the <a href="#mailing-lists-irc">users mailing list</a> and other channels mentioned
-here. There are also a number of external companies and professionals ready to help, see the user-maintained list at

-<h2 id="mailing-lists-chat">Mailing Lists & Chat</h2>
-<p>We use <a href="https://apache.org/foundation/mailinglists.html">mailing lists</a> for all official project communications.
-To subscribe or unsubscribe you need to send an email to special addresses (e.g. users-subscribe@solr.apache.org to subscribe to the users list).
-This email must be sent from <strong>the email address you want to subscribe as or unsubscribe from</strong>. You will then need to
-confirm by replying to an automated e-mail from the list software. Clicking the <code>SUBSCRIBE</code> or <code>UNSUBSCRIBE</code> buttons below
-will open your e-mail software with a pre-filled email that is ready to send. </p>
-<h4 id="mailing-list-etiquette">Mailing list etiquette</h4>
-<p>Written communication is hard and prone to misunderstandings. We recommend reading <a href="https://community.apache.org/contributors/etiquette">ComDev's etiquette page</a> for some practical tips on how to improve.</p>
-<h4 id="solr-user-list-userssolrapacheorg">Solr User List: users@solr.apache.org</h4>
-<p>This list is for users of Solr to ask questions, share knowledge, and discuss issues. We strongly encourage
-users to send usage and configuration questions and problems to this mailing list. Before filing an issue in
-the JIRA issue tracker, make sure it's a real bug and that it hasn't been already discovered by discussing it here.</p>

-<h4 id="irc">IRC</h4>
-<p>There are two primary IRC channels dedicated to Solr at libera.chat.</p>
-<p>• #solr -- Channel for Solr user questions</p>
-<p>• #solr-dev -- Hangout for discussion of Solr development</p>
-<p>The IRC channel can be used for online discussion about Solr related stuff,
-but developers should be careful to transfer all the official decisions or useful discussions to the issue
-tracking system. Note that the users mailing list will reach a lot more people than the IRC channel,
-but if it's the right time of day, the IRC channel can offer a more interactive experience with faster turnaround.</p>
-<p><a href="https://cwiki.apache.org/confluence/display/SOLR/IRCChannels">This wiki page</a> has links to a web-based IRC client, and a
-wealth of information about how to get the most out of the IRC channels.</p>
-<h4 id="slack">Slack</h4>
-<ul>
-<li>
-<p>The project's Slack channel is <code>#solr-dev</code> in the <code>the-asf</code> organization. This is primarily for developer
- discussions and not meant as support channels. Link: <a href="https://the-asf.slack.com/messages/CE70MDPMF">https://the-asf.slack.com/messages/CE70MDPMF</a></p>
-</li>
-<li>
-<p>There are unofficial slack organizations for Solr support</p>
-<ul>
-<li>A community maintained/unofficial Slack organization that relays messages bi-directionally to/from the official IRC channels. Link: <a href="https://s.apache.org/solr-slack">https://s.apache.org/solr-slack</a></li>
-<li>For relevance related discussions (Solr and other search engines), there's Relevance Slack: <a href="https://relevancy.slack.com">https://relevancy.slack.com</a>. Sign up via <a href="https://opensourceconnections.com/slack">https://opensourceconnections.com/slack</a></li>
-</ul>
-</li>
-</ul>
-<h2 id="issue-tracker">Issue tracker</h2>
-<p>Solr uses the ASF JIRA instance.</p>
-<p>You can browse, search, and create issues <a href="https://issues.apache.org/jira/browse/SOLR">here</a>.
-Patches welcome! This is not the correct place to start when you need support. Problems should be
-discussed on the mailing list and/or via IRC before creating an issue.</p>
-<h2 id="how-to-contribute">How To Contribute</h2>
-<p>Looking to contribute to Solr? Read the <a href="https://cwiki.apache.org/confluence/display/SOLR/HowToContribute">instructions</a> on
-contributing and then submit a patch!</p>
-<h2 id="code-of-conduct">Code of Conduct</h2>
-<p>For a large and diverse community like ours to be friendly, welcoming and respectful, we recognize the need for some guidelines. The project follows <a href="https://www.apache.org/foundation/policies/conduct">Apache's Code of Conduct statement</a>. Please take some time to read and understand it.</p>
-<p>If you feel there has been a violation of this code, please point out your concerns publicly in a friendly and matter of fact manner. Nonverbal communication is prone to misinterpretation and misunderstanding. Everyone has bad days and sometimes says things they regret later. Someone else's communication style may clash with yours, but the difference can be amicably resolved. After pointing out your concerns please be generous upon receiving an apology.</p>
-<p>Should there be repeated instances of code of conduct violations, or if there is an obvious and severe violation, the Solr PMC may become involved.</p>
-<h3 id="the-apache-way">The Apache Way</h3>
-<p>As an Apache project we strive to follow <a href="http://theapacheway.com/">The Apache Way</a>. If you are new to the community or to open source in general, you may benefit from understanding our core values as a community, and why we operate the way we do.</p>
-<h2 id="version-control">Version Control</h2>
-<p>The Solr source code resides in the Apache <a href="http://git.apache.org">GIT</a> repository. Various GIT clients
-can be obtained from <a href="https://git-scm.com/">git-scm.com</a>. There are also GIT integrations for various
-IDEs. For Eclipse, look at <a href="http://www.eclipse.org/egit/">EGit</a>. IntelliJ has git support bundled, if you
-have installed the command line version.</p>
-<h4 id="web-access-read-only">Web Access (read-only)</h4>
-<p>The source code can be browsed at <a href="https://github.com/apache/solr">https://github.com/apache/solr</a> and also <a href="https://gitbox.apache.org/repos/asf?p=solr.git">https://gitbox.apache.org/repos/asf?p=solr.git</a>.
-No GIT client software is required.</p>
-<h4 id="cloning-the-repository">Cloning the repository</h4>
-<p>To work on the code locally, you may clone the git repository:</p>
-<div class="codehilite"><pre><span></span><code><span class="err">git clone https://github.com/apache/solr.git</span>
-</code></pre></div>
-
-<p>Then use GitHub's <a href="https://docs.github.com/en/github/getting-started-with-github/fork-a-repo">fork feature</a>
-to obtain a personal fork from which you can later contribute your changes through a
-<a href="https://cwiki.apache.org/confluence/display/solr/HowToContribute#HowToContribute-WorkingwithGitHub">Pull Request</a>
-or a <a href="https://cwiki.apache.org/confluence/display/solr/HowToContribute#HowToContribute-Generatingapatch">patch in Jira</a>.</p>
-<p>You may alternatively choose to clone apache's git mirror at <code>https://gitbox.apache.org/repos/asf/solr.git</code>.</p>

- <p>Apache Solr is under active development with frequent feature releases on the current major version.

-
- <p>Large changes or changes that break compatibility with existing functionality are normally only included in the
- <strong>next</strong> major version.</p>

-<p><strong>Versions Affected:</strong><br>
-All versions prior to 8.11.1. Affected platforms: Windows.</p>
-<p><strong>Description:</strong><br>
-An Improper Input Validation vulnerability in DataImportHandler of Apache Solr allows an attacker to provide a Windows UNC path resulting in an SMB network call being made from the Solr host to another host on the network. If the attacker has wider access to the network, this may lead to SMB attacks, which may result in:</p>
-<ul>
-<li>The exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes),</li>
-<li>In case of misconfigured systems, SMB Relay Attacks which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution</li>
-</ul>
-<p>This issue affects all Apache Solr versions prior to 8.11.1. This issue only affects Windows.</p>
-<p><strong>Mitigation:</strong><br>
-Upgrade to Solr 8.11.1, and/or ensure only trusted clients can make requests to Solr's DataImport handler.</p>

-<p><strong>Versions Affected:</strong>
-7.4.0 to 7.7.3, 8.0.0 to 8.11.0</p>
-<p><strong>Description:</strong>
-Apache Solr releases prior to 8.11.1 were using a bundled version of the Apache Log4J library vulnerable to RCE. For full impact and additional detail consult the Log4J security page.</p>
-<p>Apache Solr releases prior to 7.4 (i.e. Solr 5, Solr 6, and Solr 7 through 7.3) use Log4J 1.2.17 which may be vulnerable for installations using non-default logging configurations that include the JMS Appender, see <a href="https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126">https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126</a> for discussion.</p>
-<p>Solr's Prometheus Exporter uses Log4J as well but it does not log user input or data, so we don't see a risk there.</p>
-<p>Solr is <em>not</em> vulnerable to the followup <strong>CVE-2021-45046</strong> and <strong>CVE-2021-45105</strong>. A listing of these and other CVEs with some justifications are listed in Solr's wiki: <a href="https://cwiki.apache.org/confluence/display/SOLR/SolrSecurity#SolrSecurity-SolrandVulnerabilityScanningTools">https://cwiki.apache.org/confluence/display/SOLR/SolrSecurity#SolrSecurity-SolrandVulnerabilityScanningTools</a> [...]
-<p><strong>Mitigation:</strong>
-Any of the following are enough to prevent this vulnerability for Solr servers:</p>
-<ul>
-<li>Upgrade to <code>Solr 8.11.1</code> or greater (when available), which will include an updated version (<code>&gt;= 2.16.0</code>) of the Log4J dependency.</li>
-<li>If you are using Solr's official docker image, it has already been mitigated in all versions listed as supported on Docker Hub: <a href="https://hub.docker.com/_/solr">https://hub.docker.com/_/solr</a>. You may need to re-pull the image.</li>
-<li>Manually update the version of Log4J on your runtime classpath and restart your Solr application.</li>
-<li>(Linux/MacOS) Edit your <code>solr.in.sh</code> file to include:
- <code>SOLR_OPTS="$SOLR_OPTS -Dlog4j2.formatMsgNoLookups=true"</code></li>
-<li>(Windows) Edit your <code>solr.in.cmd</code> file to include:
- <code>set SOLR_OPTS=%SOLR_OPTS% -Dlog4j2.formatMsgNoLookups=true</code></li>
-<li>Follow any of the other mitgations listed at <a href="https://logging.apache.org/log4j/2.x/security.html">https://logging.apache.org/log4j/2.x/security.html</a></li>
-</ul>
-<p>The Log4J security page refers to setting <code>log4j2.formatMsgNoLookups=true</code> as a "discredited" mitigation. In reality, it depends.
-We've looked at the root cause and audited the code paths that lead to the vulnerability, and we feel confident in this mitigation being sufficient for Solr.
-See <a href="https://lists.apache.org/thread/kgh63sncrsm2bls884pg87mnt8vqztmz">https://lists.apache.org/thread/kgh63sncrsm2bls884pg87mnt8vqztmz</a> for discussion.</p>

-<p><strong>Versions Affected:</strong>
-7.0.0 to 7.7.3
-8.0.0 to 8.8.1</p>
-<p><strong>Description:</strong>
-The ReplicationHandler (normally registered at "/replication" under a Solr core) has a "masterUrl" (also "leaderUrl" alias) parameter that is used to designate another ReplicationHandler on another Solr core to replicate index data into the local core.
-To prevent a SSRF vulnerability, Solr ought to check these parameters against a similar configuration it uses for the "shards" parameter. Prior to this bug getting fixed, it did not.</p>
-<p><strong>Mitigation:</strong>
-Any of the following are enough to prevent this vulnerability:</p>
-<ul>
-<li>Upgrade to <code>Solr 8.8.2</code> or greater.</li>
-<li>If upgrading is not an option, consider applying the patch in <a href="https://issues.apache.org/jira/browse/SOLR-15217">SOLR-15217</a></li>
-<li>Ensure that any access to the replication handler is purely internal to Solr. Typically, it's only accessed externally for diagnostic/informational purposes.</li>

-When starting Apache Solr versions prior to 8.8.2, configured with the SaslZkACLProvider or VMParamsAllAndReadonlyDigestZkACLProvider and no existing security.json znode, if the optional read-only user is configured then Solr would not treat that node as a sensitive path and would allow it to be readable.

-<li>Start using <a href="/community.html#version-control">the new git location</a> by cloning or defining a new git remote</li>
-<li>Realize that lucene will be a build dependency of Solr on the main branch (once the code migration is done)</li>
-<li>Backported bug fixes for Solr 8.8 must be submitted to the Lucene git, for a joint bugfix release</li>

-6.6.0 to 6.6.6

-8.0.0 to 8.6.2</p>
-<p><strong>Description:</strong>
-Solr prevents some features considered dangerous (which could be used for remote code execution) to be configured in a ConfigSet that's uploaded via API without authentication/authorization. The checks in place to prevent such features can be circumvented by using a combination of UPLOAD/CREATE actions.</p>
-<p><strong>Mitigation:</strong>
-Any of the following are enough to prevent this vulnerability:</p>
-<ul>
-<li>Disable UPLOAD command in ConfigSets API if not used by setting the system property: <code>configset.upload.enabled</code> to <code>false</code> (<a href="https://solr.apache.org/guide/8_6/configsets-api.html">see docs</a>)</li>
-<li>Use Authentication/Authorization and make sure unknown requests aren't allowed (<a href="https://solr.apache.org/guide/8_6/authentication-and-authorization-plugins.html">see docs</a>)</li>
-<li>Upgrade to <code>Solr 8.6.3</code> or greater.</li>
-<li>If upgrading is not an option, consider applying the patch in <a href="https://issues.apache.org/jira/browse/SOLR-14663">SOLR-14663</a></li>
-<li>No Solr API, including the Admin UI, is designed to be exposed to non-trusted parties. Tune your firewall so that only trusted computers and people are allowed access</li>

-<p><strong>Versions Affected:</strong><br>
-Before Solr 8.6. Some risks are specific to Windows.</p>
-<p><strong>Description:</strong>
-Reported in SOLR-14515 (private) and fixed in SOLR-14561 (public), released in Solr version 8.6.0.
-The Replication handler (https://solr.apache.org/guide/8_6/index-replication.html#http-api-commands-for-the-replicationhandler) allows commands backup, restore and deleteBackup. Each of these take a location parameter, which was not validated, i.e you could read/write to any location the solr user can access. </p>
-<p>On a windows system SMB paths such as \10.0.0.99\share\folder may also be used, leading to:</p>
-<ul>
-<li>The possibility of restoring another SolrCore from a server on the network (or mounted remote file system) may lead to:<ul>
-<li>Exposing search index data that the attacker should otherwise not have access to</li>
-<li>Replacing the index data entirely by loading it from a remote file system that the attacker controls</li>
-</ul>
-</li>
-<li>Launching SMB attacks which may result in:<ul>
-<li>The exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes),</li>
-<li>In case of misconfigured systems, SMB Relay Attacks which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution </li>
-</ul>
-</li>
-</ul>
-<p><strong>Mitigation:</strong>
-Upgrade to Solr 8.6, and/or ensure only trusted clients can make requests of Solr's replication handler.</p>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong>
-5.0.0 to 8.3.1</p>
-<p><strong>Description:</strong><br>
-The affected versions are vulnerable to a Remote Code Execution through the
-VelocityResponseWriter. A Velocity template can be provided through
-Velocity templates in a configset <code>velocity/</code> directory or as a parameter.
-A user defined configset could contain renderable, potentially malicious,
-templates. Parameter provided templates are disabled by default, but can
-be enabled by setting <code>params.resource.loader.enabled</code> by defining a
-response writer with that setting set to <code>true</code>. Defining a response
-writer requires configuration API access.</p>
-<p>Solr 8.4 removed the params resource loader entirely, and only enables the
-configset-provided template rendering when the configset is <code>trusted</code> (has
-been uploaded by an authenticated user).</p>
-<p><strong>Mitigation:</strong><br>
-Ensure your network settings are configured so that only trusted traffic
-communicates with Solr, especially to the configuration APIs.</p>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong><br>
-Solr 8.1.1 and 8.2.0 for Linux</p>
-<p><strong>Description:</strong><br>
-The 8.1.1 and 8.2.0 releases of Apache Solr contain an
-insecure setting for the ENABLE_REMOTE_JMX_OPTS configuration option
-in the default solr.in.sh configuration file shipping with Solr.</p>
-<p>Windows users are not affected.</p>
-<p>If you use the default solr.in.sh file from the affected releases, then
-JMX monitoring will be enabled and exposed on RMI_PORT (default=18983),
-without any authentication. If this port is opened for inbound traffic
-in your firewall, then anyone with network access to your Solr nodes
-will be able to access JMX, which may in turn allow them to upload
-malicious code for execution on the Solr server.</p>
-<p>The vulnerability is already public [1] and mitigation steps were
-announced on project mailing lists and news page [3] on August 14th,
-without mentioning RCE at that time.</p>
-<p><strong>Mitigation:</strong><br>
-Make sure your effective solr.in.sh file has ENABLE_REMOTE_JMX_OPTS set
-to 'false' on every Solr node and then restart Solr. Note that the
-effective solr.in.sh file may reside in /etc/defaults/ or another
-location depending on the install. You can then validate that the
-'com.sun.management.jmxremote*' family of properties are not listed in
-the "Java Properties" section of the Solr Admin UI, or configured in a
-secure way.</p>
-<p>There is no need to upgrade or update any code.</p>
-<p>Remember to follow the Solr Documentation's advice to never expose Solr
-nodes directly in a hostile network environment.</p>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong></p>
-<ul>
-<li>5.0.0 to 5.5.5</li>
-<li>6.0.0 to 6.6.5</li>
-</ul>
-<p><strong>Description:</strong><br>
-The DataImportHandler, an optional but popular module to pull in data from
-databases and other sources, has a feature in which the whole DIH
-configuration can come from a request's "dataConfig" parameter. The debug
-mode of the DIH admin screen uses this to allow convenient debugging /
-development of a DIH config. Since a DIH config can contain scripts, this
-parameter is a security risk. Starting with version 8.2.0 of Solr, use of
-this parameter requires setting the Java System property
-<code>enable.dih.dataConfigParam</code> to true.</p>
-<p><strong>Mitigation:</strong> </p>
-<ul>
-<li>Upgrade to 8.2.0 or later, which is secure by default.</li>
-<li>or, edit solrconfig.xml to configure all DataImportHandler usages with an "invariants" section listing the "dataConfig" parameter set to am empty string.</li>
-<li>Ensure your network settings are configured so that only trusted traffic communicates with Solr, especially to the DIH request handler. This is a best practice to all of Solr.</li>

-<ul>
-<li>
-<p>Solr now uses HTTP/2 for inter-node communication to attain greater efficiency.
-Details: Solr is switching from Apache HttpClient to Jetty Client for adding HTTP/2 support.
-Most frequent inter-communication between nodes like indexing and query are now sent in HTTP/2.
-HTTP/1.1 practically allows only one outstanding request per TCP connection this means that for sending multiple requests at the same time multiple TCP connections must be established.
-This leads to waste of resources on both-sides and long GC-pause.
-Solr 8 with HTTP/2 support overcomes that problem by allowing multiple requests can be sent in parallel using a same TCP connection.</p>
-</li>
-<li>
-<p>Nested documents (AKA child documents or block join) is significantly improved.
-Most improvements come from storing and leveraging more information about the relationships in the index, like the named relationship between a child and its parent.
-This information is used by the [child] doc transformer to return children in nested form instead of flat.
-There is plenty more that can be done with this in the future.
-Another key improvement is that nested documents can be deleted or replaced in a natural way without orphaning child documents; although care is still needed with delete-by-query.</p>
-</li>
-</ul>
-<p>Being a major release, Solr 8 removes many deprecated APIs, changes various parameter defaults and behavior. Some changes may require a re-index of your content.
-You are thus encouraged to thoroughly read the "Upgrade Notes" at:</p>

-<p><strong>Description:</strong><br>
-ConfigAPI allows to configure Solr's JMX server via an HTTP POST request.
-By pointing it to a malicious RMI server, an attacker could take advantage
-of Solr's unsafe deserialization to trigger remote code execution on the
-Solr side.</p>
-<p><strong>Mitigation:</strong><br>
-Any of the following are enough to prevent this vulnerability:</p>
-<ul>
-<li>Upgrade to Apache Solr 7.0 or later.</li>
-<li>Disable the ConfigAPI if not in use, by running Solr with the system property “disable.configEdit=true”</li>
-<li>If upgrading or disabling the Config API are not viable options, apply patch in [1] and re-compile Solr.</li>
-<li>Ensure your network settings are configured so that only trusted traffic is allowed to ingress/egress your hosts running Solr.</li>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong></p>
-<ul>
-<li>Solr 1.2 to 6.6.2</li>
-<li>Solr 7.0.0 to 7.2.1</li>
-</ul>
-<p><strong>Description:</strong><br>
-The details of this vulnerability were reported to the Apache Security mailing list. </p>
-<p>This vulnerability relates to an XML external entity expansion (XXE) in the
-<code>&amp;dataConfig=&lt;inlinexml&gt;</code> parameter of Solr's DataImportHandler. It can be
-used as XXE using file/ftp/http protocols in order to read arbitrary local
-files from the Solr server or the internal network. See [1] for more details.</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 6.6.3 or Solr 7.3.0 releases both
-of which address the vulnerability. Once upgrade is complete, no other steps
-are required. Those releases disable external entities in anonymous XML files
-passed through this request parameter. </p>
-<p>If users are unable to upgrade to Solr 6.6.3 or Solr 7.3.0 then they are
-advised to disable data import handler in their solrconfig.xml file and
-restart their Solr instances. Alternatively, if Solr instances are only used
-locally without access to public internet, the vulnerability cannot be used
-directly, so it may not be required to update, and instead reverse proxies or
-Solr client applications should be guarded to not allow end users to inject
-<code>dataConfig</code> request parameters. Please refer to [2] on how to correctly
-secure Solr servers.</p>

-<p><strong>Description:</strong><br>
-Apache Solr uses Apache Tika for parsing binary file types such as
-doc, xls, pdf etc. Apache Tika wraps the jmatio parser
-(https://github.com/gradusnikov/jmatio) to handle MATLAB files. The
-parser uses native deserialization on serialized Java objects embedded
-in MATLAB files. A malicious user could inject arbitrary code into a
-MATLAB file that would be executed when the object is deserialized.</p>
-<p>This vulnerability was originally described at
-http://mail-archives.apache.org/mod_mbox/tika-user/201611.mbox/%3C2125912914.1308916.1478787314903%40mail.yahoo.com%3E</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 5.5.5 or Solr 6.6.2 or Solr 7.1.0
-releases which have fixed this vulnerability.</p>
-<p>Solr 5.5.5 upgrades the jmatio parser to v1.2 and disables the Java
-deserialisation support to protect against this vulnerability.</p>
-<p>Solr 6.6.2 and Solr 7.1.0 have upgraded the bundled Tika to v1.16.</p>
-<p>Once upgrade is complete, no other steps are required.</p>

-<li>Solr 7.0.0 to 7.0.1</li>
-</ul>
-<p><strong>Description:</strong><br>
-The details of this vulnerability were reported on public mailing
-lists. See https://s.apache.org/FJDl</p>
-<p>The first vulnerability relates to XML external entity expansion in
-the XML Query Parser which is available, by default, for any query
-request with parameters deftype=xmlparser. This can be exploited to
-upload malicious data to the /upload request handler. It can also be
-used as Blind XXE using ftp wrapper in order to read arbitrary local
-files from the solr server.</p>
-<p>The second vulnerability relates to remote code execution using the
-RunExecutableListener available on all affected versions of Solr.</p>
-<p>At the time of the above report, this was a 0-day vulnerability with a
-working exploit affecting the versions of Solr mentioned in the
-previous section. However, mitigation steps were announced to protect
-Solr users the same day. See
-https://solr.apache.org/news.html#12-october-2017-please-secure-your-apache-solr-servers-since-a-zero-day-exploit-has-been-reported-on-a-public-mailing-list</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 6.6.2 or Solr 7.1.0
-releases both of which address the two vulnerabilities. Once upgrade is
-complete, no other steps are required.</p>
-<p>If users are unable to upgrade to Solr 6.6.2 or Solr 7.1.0 then they
-are advised to restart their Solr instances with the system parameter
-<code>-Ddisable.configEdit=true</code>. This will disallow any changes to be made
-to your configurations via the Config API. This is a key factor in
-this vulnerability, since it allows GET requests to add the
-RunExecutableListener to your config. Users are also advised to re-map
-the XML Query Parser to another parser to mitigate the XXE
-vulnerability. For example, adding the following to the solrconfig.xml
-file re-maps the xmlparser to the edismax parser:
-<code>&lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&gt;</code></p>

-This has been assigned a public CVE (CVE-2017-12629) which we
-will reference in future communication about resolution and mitigation
-steps.</p>
-<p>Here is what we're recommending and what we're doing now:</p>
-<ul>
-<li>
-<p>Until fixes are available, all Solr users are advised to restart their
-Solr instances with the system property <code>-Ddisable.configEdit=true</code>.
-This will disallow any changes to be made to configurations via the
-Config API. This is a key factor in this vulnerability, since it allows
-GET requests to add the RunExecutableListener to the config. This is
-sufficient to protect you from this type of attack, but means you cannot
-use the edit capabilities of the Config API until the other fixes
-described below are in place. Users are also advised to remap
-the XML Query Parser to another parser to mitigate the XXE
-vulnerability. For example, adding the following to the solrconfig.xml
-file maps the <code>xmlparser</code> to the <code>edismax</code> parser:
-<code>&lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&gt;</code>.</p>
-</li>
-<li>
-<p>A new release of Lucene/Solr was in the vote phase, but we have now
-pulled it back to be able to address these issues in the upcoming 7.1
-release. We will also determine mitigation steps for users on earlier
-versions, which may include a 6.6.2 release for users still on 6.x.</p>
-</li>
-<li>
-<p>The RunExecutableListener will be removed in 7.1. It was previously
-used by Solr for index replication but has been replaced and is no
-longer needed.</p>
-</li>
-<li>
-<p>The XML Parser will be fixed and the fixes will be included in the 7.1
-release.</p>
-</li>
-<li>
-<p>The 7.1 release was already slated to include a change to disable the
-<code>stream.body</code> parameter by default, which will further help protect
-systems.</p>

-<h3 id="highlights-for-this-solr-release-include">Highlights for this Solr release include:</h3>
-<ul>
-<li>
-<p>Replica Types - Solr 7 supports different replica types, which handle updates differently. In addition to pure NRT operation where all replicas build an index and keep a replication log, you can now also add so called PULL replicas, achieving the read-speed optimized benefits of a master/slave setup while at the same time keeping index redundancy.</p>
-</li>
-<li>
-<p>Auto-scaling. Solr can now allocate new replicas to nodes using a new auto scaling policy framework. This framework will in future releases enable Solr to move shards around based on load, disk etc.</p>
-</li>
-<li>
-<p>Indented JSON is now the default response format for all APIs, pass wt=xml and/or indent=off to use the previous unindented XML format.</p>
-</li>
-<li>
-<p>The JSON Facet API now supports two-phase facet refinement to ensure accurate counts and statistics for facet buckets returned in distributed mode.</p>
-</li>
-<li>
-<p>Streaming Expressions adds a new statistical programming syntax for the statistical analysis of sql queries, random samples, time series and graph result sets.</p>
-</li>
-<li>
-<p>Analytics Component version 2.0, which now supports distributed collections, expressions over multivalued fields, a new JSON request language, and more.</p>
-</li>
-<li>
-<p>The new v2 API, exposed at /api/ and also supported via SolrJ, is now the preferred API, but /solr/ continues to work.</p>
-</li>
-<li>
-<p>A new '_default' configset is used if no config is specified at collection creation. The data-driven functionality of this configset indexes strings as analyzed text while at the same time copying to a '*_str' field suitable for faceting.</p>
-</li>
-<li>
-<p>Solr 7 is tested with and verified to support Java 9.</p>

-<li>Solr 5.3 to 5.5.4</li>
-<li>Solr 6.0 to 6.5.1</li>
-</ul>
-<p><strong>Description:</strong><br>
-Solr uses a PKI based mechanism to secure inter-node communication
-when security is enabled. It is possible to create a specially crafted
-node name that does not exist as part of the cluster and point it to a
-malicious node. This can trick the nodes in cluster to believe that
-the malicious node is a member of the cluster. So, if Solr users have
-enabled BasicAuth authentication mechanism using the BasicAuthPlugin
-or if the user has implemented a custom Authentication plugin, which
-does not implement either "HttpClientInterceptorPlugin" or
-"HttpClientBuilderPlugin", his/her servers are vulnerable to this
-attack. Users who only use SSL without basic authentication or those
-who use Kerberos are not affected.</p>
-<p><strong>Mitigation</strong>:</p>
-<ul>
-<li>6.x users should upgrade to 6.6.0 or higher</li>

-hit highlighting, faceted search and analytics, rich document parsing,
-geospatial search, extensive REST APIs as well as parallel SQL. Solr is
-enterprise grade, secure and highly scalable, providing fault tolerant
-distributed search and indexing, and powers the search and navigation features
-of many of the world's largest internet sites.</p>
-<p>Solr 6.5.1 is available for immediate download at:
-<a href="https://solr.apache.org/downloads.html">https://solr.apache.org/downloads.html</a></p>

-<p><strong>Severity:</strong> Moderate</p>
-<p><strong>Vendor:</strong><br>
-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong><br>
-Solr 1.4 to 6.4.0</p>
-<p><strong>Description:</strong><br>
-When using the Index Replication feature, Solr nodes can pull index files from
-a master/leader node using an HTTP API which accepts a file name. However,
-Solr did not validate the file name, hence it was possible to craft a special
-request involving path traversal, leaving any file readable to the Solr server
-process exposed. Solr servers protected and restricted by firewall rules
-and/or authentication would not be at risk since only trusted clients and users
-would gain direct HTTP access.</p>
-<p><strong>Mitigation:</strong></p>
-<ul>
-<li>6.x users should upgrade to 6.4.1</li>
-<li>5.x users should upgrade to 5.5.4</li>
-<li>4.x, 3.x and 1.4 users should upgrade to a supported version of Solr or setup proper firewalling, or disable the ReplicationHandler if not in use.</li>

-</li>
-<li>
-<p>Support facet scoring with the scoreNodes expression</p>
-</li>

-</li>
-</ul>
-<p>Faceting:</p>
-<ul>
-<li>
-<p>facet.method=enum can bypass exact counts calculation with facet.exists=true, it just returns 1 for terms which exists in result docset</p>
-</li>
-<li>
-<p>Add "overrequest" parameter to JSON Facet API to control amount of overrequest on a distributed terms facet</p>
-</li>
-</ul>

-<li>
-<p>You can now set Solr's log level through environment variable SOLR_LOG_LEVEL</p>
-</li>
-<li>
-<p>GC logs are rotated by JVM to a max of 9 files, and backed up via bin/solr scripts</p>
-</li>
-<li>
-<p>Solr's logging verbosity at the INFO level has been greatly reduced by moving much logging to DEBUG level</p>
-</li>
-<li>
-<p>The solr-8983-console.log file now only logs STDOUT and STDERR output, not all log4j logs as before</p>
-</li>
-<li>
-<p>Solr's main log file, solr.log, is now written to SOLR_LOGS_DIR without changing log4j.properties</p>
-</li>
-</ul>
-<p>Start scripts:</p>
-<ul>
-<li>
-<p>Allow 180 seconds for shutdown before killing solr (configurable, old limit 5s) (Unix only)</p>
-</li>
-<li>
-<p>Start scripts now exits with informative message if using wrong Java version</p>
-</li>
-<li>
-<p>Fixed "bin/solr.cmd zk upconfig" command which was broken on windows</p>
-</li>
-<li>
-<p>You can now ask for DEBUG logging simply with '-v' option, and for WARN logging with '-q' option</p>
-</li>
-</ul>
-<p>SolrCloud:</p>
-<ul>
-<li>
-<p>The DELETEREPLICA API can accept a 'count' parameter and remove "count" number of replicas from each shard if the shard name is not provided</p>
-</li>
-<li>
-<p>The config API shows expanded useParams for request handlers inline</p>
-</li>
-<li>
-<p>Ability to create/delete/list snapshots at collection level</p>
-</li>
-<li>
-<p>The modify collection API now waits for the modified properties to show up in the cluster state before returning</p>
-</li>
-<li>
-<p>Many bug fixes related to SolrCloud recovery for data safety and faster recovery times.</p>
-</li>
-</ul>
-<p>Security:</p>
-<ul>
-<li>
-<p>SolrJ now supports Kerberos delegation tokens</p>
-</li>
-<li>
-<p>Pooled SSL connections were not being re-used. This is now fixed.</p>
-</li>
-<li>
-<p>Fix for the blockUnknown property which made inter-node communication impossible</p>
-</li>
-<li>
-<p>Support SOLR_AUTHENTICATION_OPTS and SOLR_AUTHENTICATION_CLIENT_CONFIGURER in windows bin/solr.cmd script</p>
-</li>
-<li>
-<p>New parameter -u <user:pass> in bin/post to pass basicauth credentials</p>
-</li>
-</ul>
-<p>Misc changes:</p>
-<ul>
-<li>
-<p>Optimizations to lower memory allocations when indexing JSON as well as for replication between solr cloud nodes.</p>
-</li>
-<li>
-<p>A new Excel workbook (.xlsx) response writer has been added. Use 'wt=xlsx' request parameter on a query request to enable.</p>

-<p>Solr 5.3 Release Highlights:</p>
-<ul>
-<li>In addition to many other improvements in the security framework, Solr now includes an AuthenticationPlugin implementing HTTP Basic Auth that stores credentials securely in ZooKeeper. This is a simple way to require a username and password for anyone accessing Solr’s admin screen or APIs.</li>
-<li>In built AuthorizationPlugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in ZooKeeper.</li>

-<li>Major improvements in performance of the new Facet Module / JSON Facet API.</li>
-<li>Query and Range Facets under Pivot Facets. Just like the JSON Facet API, pivot facets can how nest other facet types such as range and query facets.</li>
-<li>More Like This Query Parser options. The MoreLikeThis QParser now supports all options provided by the MLT Handler. The query parser is much more versatile than the handler as it works in cloud mode as well as anywhere a normal query can be specified.</li>

-<ul>
-<li>LocalStatsCache: Local document stats.</li>
-<li>ExactStatsCache: One time use aggregation</li>
-<li>ExactSharedStatsCache: Stats shared across requests</li>
-<li>LRUStatsCache: Stats shared in an LRU cache across requests</li>
-</ul>
-</li>
-<li>
-<p>Solr will no longer ship a war file and instead be a downloadable application.</p>

-</li>
-<li>
-<p>There's now an option to not shuffle the nodeSet provided during collection creation.</p>
-</li>
-<li>
-<p>Option to configure bandwidth usage by Replication handler to prevent it from using up all the bandwidth.</p>
-</li>
-<li>
-<p>Splitting of clusterstate to per-collection enables scalability improvement in SolrCloud. This is also the default format for new Collections that would be created going forward.</p>
-</li>
-<li>
-<p>timeAllowed is now used to prematurely terminate requests during query expansion and SolrClient request retry.</p>
-</li>
-<li>
-<p>pivot.facet results can now include nested stats.field results constrained by those pivots.</p>
-</li>
-<li>
-<p>stats.field can be used to generate stats over the results of arbitrary numeric functions.
- It also allows for requesting for statistics for pivot facets using tags.</p>
-</li>
-<li>
-<p>A new DateRangeField has been added for indexing date ranges, especially multi-valued ones.</p>
-</li>
-<li>
-<p>Spatial fields that used to require units=degrees now take distanceUnits=degrees/kilometers miles instead.</p>
-</li>
-<li>

-<p>Users of Apache Solr are strongly advised to keep the module disabled if they don't use it.
-Alternatively, users of Apache Solr 4.8.0, 4.8.1, or 4.9.0 can update the affected libraries by
-replacing the vulnerable JAR files in the distribution folder. Users of previous versions have
-to update their Solr release first, patching older versions is impossible.</p>
-<h3 id="to-replace-the-vulnerable-jar-files-follow-these-steps">To replace the vulnerable JAR files follow these steps:</h3>
-<ul>
-<li>
-<p>Download the <a href="http://poi.apache.org/download.html#POI-3.10.1">Apache POI 3.10.1</a> binary release.</p>
-</li>
-<li>
-<p>Unzip the archive.</p>
-</li>
-<li>
-<p>Delete the following files in your "solr-4.X.X/contrib/extraction/lib" folder:</p>
-<ul>
-<li>poi-3.10-beta2.jar</li>
-<li>poi-ooxml-3.10-beta2.jar</li>
-<li>poi-ooxml-schemas-3.10-beta2.jar</li>
-<li>poi-scratchpad-3.10-beta2.jar</li>
-<li>xmlbeans-2.3.0.jar</li>
-</ul>
-</li>
-<li>
-<p>Copy the following files from the base folder of the Apache POI distribution to the "solr-4.X.X/contrib/extraction/lib" folder:</p>
-<ul>
-<li>poi-3.10.1-20140818.jar</li>
-<li>poi-ooxml-3.10.1-20140818.jar</li>
-<li>poi-ooxml-schemas-3.10.1-20140818.jar</li>
-<li>poi-scratchpad-3.10.1-20140818.jar</li>
-</ul>
-</li>
-<li>
-<p>Copy "xmlbeans-2.6.0.jar" from POI's "ooxml-lib/" folder to the "solr-4.X.X/contrib/extraction/lib" folder.</p>
-</li>
-<li>
-<p>Verify that the "solr-4.X.X/contrib/extraction/lib" no longer contains any files with version number "3.10-beta2".</p>
-</li>
-<li>
-<p>Verify that the folder contains one xmlbeans JAR file with version 2.6.0.</p>
-</li>
-</ul>
-<p>If you just want to disable extraction of Microsoft Office documents, delete the files above and don't replace them.
-"Solr Cell" will automatically detect this and disable Microsoft Office document extraction.</p>
-<p>Coming versions of Apache Solr will have the updated libraries bundled.</p></content><category term="solr/security"></category></entry><entry><title>Apache Solr Ref Guide for 4.9 Available</title><link href="/" rel="alternate"></link><published>2014-06-30T00:00:00+00:00</published><updated>2014-06-30T00:00:00+00:00</updated><author><name>Solr Developers</name></author><id>tag:None,2014-06-30:/</id><summary type="html"><p>The Lucene PMC is pleased to announce that the [...]

-</li>
-<li>
-<p>The new {!complexphrase} query parser supports wildcards, ORs etc.
- inside Phrase Queries.</p>

-<li>
-<p>New Collections API CLUSTERSTATUS action reports the status of
- collections, shards, and replicas, and also lists collection
- aliases and cluster properties.</p>

-<p>The next release will also contain some improvements for Java 7:</p>
-<ul>
-<li>
-<p>Better file handling (especially on Windows) in the directory implementations. Files can now be deleted on windows, although the index is still open - like it was always possible on Unix environments (delete on last close semantics).</p>
-</li>
-<li>
-<p>Speed improvements in sorting comparators: Sorting now uses Java 7's own comparators for integer and long sorts, which are highly optimized by the Hotspot VM.</p>
-</li>
-</ul>
-<p>If you want to stay up-to-date with Lucene and Solr, you should upgrade your infrastructure to Java 7.
-Please be aware that you must use at least use Java 7u1.
-The recommended version at the moment is Java 7u25. Later versions like 7u40, 7u45,... have a bug causing index corrumption.
-Ideally use the Java 7u60 prerelease, which has fixed this bug. Once 7u60 is out, this will be the recommended version.
-In addition, there is no more Oracle/BEA JRockit available for Java 7, use the official Oracle Java 7.
-JRockit was never working correctly with Lucene/Solr (causing index corrumption), so this should not be an issue.
-Please also review our list of JVM bugs: <a href="http://wiki.apache.org/lucene-java/JavaBugs">http://wiki.apache.org/lucene-java/JavaBugs</a></p>
-<p><em>EDIT (as of 15 April 2014):</em> The recently released Java 7u55 fixes the above bug causing index corrumption.

-Solr has been a Lucene sub-project since its incubation in 2006, governed by the Lucene PMC,
-and has since the 3.1 release also shared source code repository with Lucene.</p>
-<h3 id="whats-the-background">What's the background?</h3>
-<p>The change was proposed by members of the Lucene PMC, and a vote in June 2020 decided
-that Solr would be a separate TLP. Later, the Lucene PMC decided that the Solr project
-would be bootstrapped with the same set of committers and PMC members as the "mother" Lucene project.</p>
-<h3 id="how-does-this-affect-users">How does this affect users?</h3>
-<p>The Solr software will not change at all as a result of this, but users will see these changes:</p>
-<ol>
-<li>Solr gets a new website at <a href="http://solr.apache.org/">solr.apache.org</a></li>
-<li>Solr gets a new download location in the mirrors</li>
-<li>The email address of the users mailing-list will change, but subscribers will be moved automatically</li>
-</ol>
-<h3 id="how-does-this-affect-developers">How does this affect developers?</h3>
-<p>Developers will have to do a number of things to adapt to the change</p>
-<ol>
-<li>Subscribe to the new mailing lists. See <a href="/community.html#mailing-lists-chat">Mailing Lists &amp; Chat</a> for instructions</li>
-<li>Start using <a href="/community.html#version-control">the new git location</a> by cloning or defining a new git remote</li>
-<li>Realize that lucene will be a build dependency of Solr on the main branch (once the code migration is done)</li>
-<li>Backported bug fixes for Solr 8.8 must be submitted to the Lucene git, for a joint bugfix release</li>
-</ol>
-<p><strong>NOTE:</strong> Some things may be in flux during the migration work.</p></content><category term="solr/news"></category></entry><entry><title>Apache Solr™ 8.8.0 available</title><link href="/apache-solrtm-880-available.html" rel="alternate"></link><published>2021-01-29T00:00:00+00:00</published><updated>2021-01-29T00:00:00+00:00</updated><author><name>Solr Developers</name></author><id>tag:None,2021-01-29:/apache-solrtm-880-available.html</id><summary t [...]

-<ul>
-<li>
-<p>Solr now uses HTTP/2 for inter-node communication to attain greater efficiency.
-Details: Solr is switching from Apache HttpClient to Jetty Client for adding HTTP/2 support.
-Most frequent inter-communication between nodes like indexing and query are now sent in HTTP/2.
-HTTP/1.1 practically allows only one outstanding request per TCP connection this means that for sending multiple requests at the same time multiple TCP connections must be established.
-This leads to waste of resources on both-sides and long GC-pause.
-Solr 8 with HTTP/2 support overcomes that problem by allowing multiple requests can be sent in parallel using a same TCP connection.</p>
-</li>
-<li>
-<p>Nested documents (AKA child documents or block join) is significantly improved.
-Most improvements come from storing and leveraging more information about the relationships in the index, like the named relationship between a child and its parent.
-This information is used by the [child] doc transformer to return children in nested form instead of flat.
-There is plenty more that can be done with this in the future.
-Another key improvement is that nested documents can be deleted or replaced in a natural way without orphaning child documents; although care is still needed with delete-by-query.</p>
-</li>
-</ul>

-<h3 id="solr-771-release-highlights">Solr 7.7.1 Release Highlights:</h3>
-<ul>
-<li>
-<p>Bugfix for ClassCastException when URPs try to read a String field which returns a ByteArrayUTF8CHarSequence (a
- regression in release 7.7.0).</p>
-</li>
-<li>
-<p>Bugfix: Autoscaling based replica placement was broken out of the box. Solr 7.6 enabled autoscaling based replica
- placement by default but in the absence of default cluster policies, autoscaling can place more than 1 replica of the
- same shard on the same node. Also, the maxShardsPerNode and createNodeSet was not respected. Due to these reasons,
- this issue reverts the default replica placement policy to the 'legacy' assignment policy that was the default until
- Solr 7.5.</p>

-<h3 id="highlights-for-this-solr-release-include">Highlights for this Solr release include:</h3>
-<ul>
-<li>
-<p>Replica Types - Solr 7 supports different replica types, which handle updates differently. In addition to pure NRT operation where all replicas build an index and keep a replication log, you can now also add so called PULL replicas, achieving the read-speed optimized benefits of a master/slave setup while at the same time keeping index redundancy.</p>
-</li>
-<li>
-<p>Auto-scaling. Solr can now allocate new replicas to nodes using a new auto scaling policy framework. This framework will in future releases enable Solr to move shards around based on load, disk etc.</p>
-</li>
-<li>
-<p>Indented JSON is now the default response format for all APIs, pass wt=xml and/or indent=off to use the previous unindented XML format.</p>
-</li>
-<li>
-<p>The JSON Facet API now supports two-phase facet refinement to ensure accurate counts and statistics for facet buckets returned in distributed mode.</p>
-</li>
-<li>
-<p>Streaming Expressions adds a new statistical programming syntax for the statistical analysis of sql queries, random samples, time series and graph result sets.</p>
-</li>
-<li>
-<p>Analytics Component version 2.0, which now supports distributed collections, expressions over multivalued fields, a new JSON request language, and more.</p>
-</li>
-<li>
-<p>The new v2 API, exposed at /api/ and also supported via SolrJ, is now the preferred API, but /solr/ continues to work.</p>
-</li>
-<li>
-<p>A new '_default' configset is used if no config is specified at collection creation. The data-driven functionality of this configset indexes strings as analyzed text while at the same time copying to a '*_str' field suitable for faceting.</p>
-</li>
-<li>
-<p>Solr 7 is tested with and verified to support Java 9.</p>

-<p>Solr is the popular, blazing fast, open source NoSQL search platform from the
-Apache Lucene project. Its major features include powerful full-text search,
-hit highlighting, faceted search and analytics, rich document parsing,
-geospatial search, extensive REST APIs as well as parallel SQL. Solr is
-enterprise grade, secure and highly scalable, providing fault tolerant
-distributed search and indexing, and powers the search and navigation features
-of many of the world's largest internet sites.</p>
-<p>Solr 6.5.1 is available for immediate download at:
-<a href="https://solr.apache.org/downloads.html">https://solr.apache.org/downloads.html</a></p>
-<p>This release includes 11 bug fixes since the 6.5.0 release. Some of the major fixes are:</p>
-<ul>

-</li>
-<li>
-<p>Fix debug related NullPointerException in solr/contrib/ltr OriginalScoreFeature class.</p>
-</li>
-<li>

-</li>
-<li>
-<p>Fix params persistence for solr/contrib/ltr (MinMax|Standard)Normalizer classes.</p>
-</li>
-<li>
-<p>The fetch() streaming expression wouldn't work if a value included query syntax chars (like :+-). Fixed, and enhanced the generated query to not pollute the queryCache.</p>
-</li>
-<li>
-<p>Disable graph query production via schema configuration <code>&lt;fieldtype ... enableGraphQueries="false"&gt;</code>. This fixes broken queries for ShingleFilter-containing query-time analyzers when request param sow=false.</p>
-</li>
-<li>
-<p>Fix indexed="false" on numeric PointFields</p>
-</li>
-<li>
-<p>SQL AVG function mis-interprets field type.</p>
-</li>
-<li>
-<p>SQL interface does not use client cache.</p>
-</li>
-<li>
-<p>edismax with sow=false fails to create dismax-per-term queries when any field is boosted.</p>

-use an earlier version instead! This is caused by a bug introduced into the
-Javadocs tool shipped with that update. The workaround was too late for this
-Lucene release. Of course, you can use the binary artifacts.</p>

-<ul>
-<li>
-<p>Optimize, store and deploy AI models in Solr</p>
-</li>
-<li>
-<p>Ability to add custom streaming expressions</p>
-</li>
-<li>
-<p>New streaming expressions such as "fetch", "executor", and "commit" added.</p>

-</li>
-<li>
-<p>Support facet scoring with the scoreNodes expression</p>
-</li>
-<li>
-<p>Retrieving docValues as stored values was sped up by using the proper leaf reader rather than ask for a global view. In extreme cases, this leads to a 100x speedup.</p>
-</li>
-</ul>
-<p>Faceting:</p>
-<ul>
-<li>
-<p>facet.method=enum can bypass exact counts calculation with facet.exists=true, it just returns 1 for terms which exists in result docset</p>
-</li>
-<li>
-<p>Add "overrequest" parameter to JSON Facet API to control amount of overrequest on a distributed terms facet</p>
-</li>

-<p>Logging:</p>
-<ul>
-<li>
-<p>You can now set Solr's log level through environment variable SOLR_LOG_LEVEL</p>
-</li>
-<li>
-<p>GC logs are rotated by JVM to a max of 9 files, and backed up via bin/solr scripts</p>
-</li>
-<li>
-<p>Solr's logging verbosity at the INFO level has been greatly reduced by moving much logging to DEBUG level</p>
-</li>
-<li>
-<p>The solr-8983-console.log file now only logs STDOUT and STDERR output, not all log4j logs as before</p>
-</li>
-<li>
-<p>Solr's main log file, solr.log, is now written to SOLR_LOGS_DIR without changing log4j.properties</p>
-</li>
-</ul>
-<p>Start scripts:</p>
-<ul>
-<li>
-<p>Allow 180 seconds for shutdown before killing solr (configurable, old limit 5s) (Unix only)</p>
-</li>
-<li>
-<p>Start scripts now exits with informative message if using wrong Java version</p>
-</li>
-<li>
-<p>Fixed "bin/solr.cmd zk upconfig" command which was broken on windows</p>
-</li>

-<p>Solr 5.3 Release Highlights:</p>
-<ul>
-<li>In addition to many other improvements in the security framework, Solr now includes an AuthenticationPlugin implementing HTTP Basic Auth that stores credentials securely in ZooKeeper. This is a simple way to require a username and password for anyone accessing Solr’s admin screen or APIs.</li>
-<li>In built AuthorizationPlugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in ZooKeeper.</li>
-<li>The JSON Facet API can now change the domain for facet commands, essentially doing a block join and moving from parents to children, or children to parents before calculating the facet data.</li>
-<li>Major improvements in performance of the new Facet Module / JSON Facet API.</li>
-<li>Query and Range Facets under Pivot Facets. Just like the JSON Facet API, pivot facets can how nest other facet types such as range and query facets.</li>
-<li>More Like This Query Parser options. The MoreLikeThis QParser now supports all options provided by the MLT Handler. The query parser is much more versatile than the handler as it works in cloud mode as well as anywhere a normal query can be specified.</li>
-<li>Added Schema API support in SolrJ</li>
-<li>Added Scoring mode for query-time join and block join.</li>
-<li>Added Smile response format</li>

-<ul>
-<li>LocalStatsCache: Local document stats.</li>
-<li>ExactStatsCache: One time use aggregation</li>
-<li>ExactSharedStatsCache: Stats shared across requests</li>
-<li>LRUStatsCache: Stats shared in an LRU cache across requests</li>
-</ul>
-</li>
-<li>
-<p>Solr will no longer ship a war file and instead be a downloadable application.</p>
-</li>
-<li>

-</li>
-<li>
-<p>Implicit registration of replication,get and admin handlers.</p>
-</li>
-<li>
-<p>Config API that supports paramsets for easily configuring solr parameters and configuring fields. This API also supports managing of pre-existing request handlers and editing common solrconfig.xml via overlay.</p>
-</li>
-<li>
-<p>API for managing blobs allows uploading request handler jars and registering them via config API.</p>
-</li>
-<li>
-<p>BALANCESHARDUNIQUE Collection API that allows for even distribution of custom replica properties.</p>
-</li>
-<li>
-<p>There's now an option to not shuffle the nodeSet provided during collection creation.</p>
-</li>
-<li>
-<p>Option to configure bandwidth usage by Replication handler to prevent it from using up all the bandwidth.</p>
-</li>
-<li>
-<p>Splitting of clusterstate to per-collection enables scalability improvement in SolrCloud. This is also the default format for new Collections that would be created going forward.</p>
-</li>
-<li>
-<p>timeAllowed is now used to prematurely terminate requests during query expansion and SolrClient request retry.</p>
-</li>
-<li>
-<p>pivot.facet results can now include nested stats.field results constrained by those pivots.</p>
-</li>
-<li>
-<p>stats.field can be used to generate stats over the results of arbitrary numeric functions.
- It also allows for requesting for statistics for pivot facets using tags.</p>
-</li>
-<li>
-<p>A new DateRangeField has been added for indexing date ranges, especially multi-valued ones.</p>
-</li>
-<li>
-<p>Spatial fields that used to require units=degrees now take distanceUnits=degrees/kilometers miles instead.</p>
-</li>
-<li>
-<p>MoreLikeThis query parser allows requesting for documents similar to an existing document and also works in SolrCloud mode.</p>

-<p>Users of Apache Solr are strongly advised to keep the module disabled if they don't use it.
-Alternatively, users of Apache Solr 4.8.0, 4.8.1, or 4.9.0 can update the affected libraries by
-replacing the vulnerable JAR files in the distribution folder. Users of previous versions have
-to update their Solr release first, patching older versions is impossible.</p>
-<h3 id="to-replace-the-vulnerable-jar-files-follow-these-steps">To replace the vulnerable JAR files follow these steps:</h3>
-<ul>
-<li>
-<p>Download the <a href="http://poi.apache.org/download.html#POI-3.10.1">Apache POI 3.10.1</a> binary release.</p>
-</li>
-<li>
-<p>Unzip the archive.</p>
-</li>
-<li>
-<p>Delete the following files in your "solr-4.X.X/contrib/extraction/lib" folder:</p>
-<ul>
-<li>poi-3.10-beta2.jar</li>
-<li>poi-ooxml-3.10-beta2.jar</li>

-<p>Verify that the "solr-4.X.X/contrib/extraction/lib" no longer contains any files with version number "3.10-beta2".</p>
-</li>
-<li>
-<p>Verify that the folder contains one xmlbeans JAR file with version 2.6.0.</p>
-</li>
-</ul>
-<p>If you just want to disable extraction of Microsoft Office documents, delete the files above and don't replace them.

-<h3 id="solr-480-release-highlights">Solr 4.8.0 Release Highlights:</h3>
-<ul>
-<li>
-<p>Apache Solr now requires Java 7 or greater (recommended is

- <code class="inline">&lt;field&gt;</code> and <code class="inline">&lt;copyField&gt;</code> definitions if desired.</p>
-</li>
-<li>
-<p>The new {!complexphrase} query parser supports wildcards, ORs etc.
- inside Phrase Queries.</p>
-</li>
-<li>
-<p>New Collections API CLUSTERSTATUS action reports the status of
- collections, shards, and replicas, and also lists collection
- aliases and cluster properties.</p>
-</li>
-<li>
-<p>Added managed synonym and stopword filter factories, which enable
- synonym and stopword lists to be dynamically managed via REST API.</p>
-</li>
-<li>
-<p>JSON updates now support nested child documents, enabling {!child}
- and {!parent} block join queries.</p>
-</li>
-<li>
-<p>Added ExpandComponent to expand results collapsed by the
- CollapsingQParserPlugin, as well as the parent/child relationship
- of nested child documents.</p>
-</li>
-<li>
-<p>Long-running Collections API tasks can now be executed
- asynchronously; the new REQUESTSTATUS action provides status.</p>
-</li>
-<li>
-<p>Added a hl.qparser parameter to allow you to define a query parser
- for hl.q highlight queries.</p>
-</li>
-<li>
-<p>In Solr single-node mode, cores can now be created using named
- configsets.</p>
-</li>
-<li>
-<p>New DocExpirationUpdateProcessorFactory supports computing an
- expiration date for documents from the "TTL" expression, as well as

-<p>The next release will also contain some improvements for Java 7:</p>
-<ul>
-<li>
-<p>Better file handling (especially on Windows) in the directory implementations. Files can now be deleted on windows, although the index is still open - like it was always possible on Unix environments (delete on last close semantics).</p>
-</li>
-<li>
-<p>Speed improvements in sorting comparators: Sorting now uses Java 7's own comparators for integer and long sorts, which are highly optimized by the Hotspot VM.</p>
-</li>
-</ul>
-<p>If you want to stay up-to-date with Lucene and Solr, you should upgrade your infrastructure to Java 7.
-Please be aware that you must use at least use Java 7u1.
-The recommended version at the moment is Java 7u25. Later versions like 7u40, 7u45,... have a bug causing index corrumption.
-Ideally use the Java 7u60 prerelease, which has fixed this bug. Once 7u60 is out, this will be the recommended version.
-In addition, there is no more Oracle/BEA JRockit available for Java 7, use the official Oracle Java 7.
-JRockit was never working correctly with Lucene/Solr (causing index corrumption), so this should not be an issue.
-Please also review our list of JVM bugs: <a href="http://wiki.apache.org/lucene-java/JavaBugs">http://wiki.apache.org/lucene-java/JavaBugs</a></p>
-<p><em>EDIT (as of 15 April 2014):</em> The recently released Java 7u55 fixes the above bug causing index corrumption.

-<p><strong>Description:</strong><br>
-An Improper Input Validation vulnerability in DataImportHandler of Apache Solr allows an attacker to provide a Windows UNC path resulting in an SMB network call being made from the Solr host to another host on the network. If the attacker has wider access to the network, this may lead to SMB attacks, which may result in:</p>
-<ul>
-<li>The exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes),</li>
-<li>In case of misconfigured systems, SMB Relay Attacks which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution</li>
-</ul>
-<p>This issue affects all Apache Solr versions prior to 8.11.1. This issue only affects Windows.</p>
-<p><strong>Mitigation:</strong><br>
-Upgrade to Solr 8.11.1, and/or ensure only trusted clients can make requests to Solr's DataImport handler.</p>

-Critical</p>
-<p><strong>Versions Affected:</strong>
-7.4.0 to 7.7.3, 8.0.0 to 8.11.0</p>
-<p><strong>Description:</strong>
-Apache Solr releases prior to 8.11.1 were using a bundled version of the Apache Log4J library vulnerable to RCE. For full impact and additional detail consult the Log4J security page.</p>
-<p>Apache Solr releases prior to 7.4 (i.e. Solr 5, Solr 6, and Solr 7 through 7.3) use Log4J 1.2.17 which may be vulnerable for installations using non-default logging configurations that include the JMS Appender, see <a href="https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126">https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126</a> for discussion.</p>
-<p>Solr's Prometheus Exporter uses Log4J as well but it does not log user input or data, so we don't see a risk there.</p>
-<p>Solr is <em>not</em> vulnerable to the followup <strong>CVE-2021-45046</strong> and <strong>CVE-2021-45105</strong>. A listing of these and other CVEs with some justifications are listed in Solr's wiki: <a href="https://cwiki.apache.org/confluence/display/SOLR/SolrSecurity#SolrSecurity-SolrandVulnerabilityScanningTools">https://cwiki.apache.org/confluence/display/SOLR/SolrSecurity#SolrSecurity-SolrandVulnerabilityScanningTools</a> [...]
-<p><strong>Mitigation:</strong>
-Any of the following are enough to prevent this vulnerability for Solr servers:</p>
-<ul>
-<li>Upgrade to <code>Solr 8.11.1</code> or greater (when available), which will include an updated version (<code>&gt;= 2.16.0</code>) of the Log4J dependency.</li>
-<li>If you are using Solr's official docker image, it has already been mitigated in all versions listed as supported on Docker Hub: <a href="https://hub.docker.com/_/solr">https://hub.docker.com/_/solr</a>. You may need to re-pull the image.</li>
-<li>Manually update the version of Log4J on your runtime classpath and restart your Solr application.</li>
-<li>(Linux/MacOS) Edit your <code>solr.in.sh</code> file to include:
- <code>SOLR_OPTS="$SOLR_OPTS -Dlog4j2.formatMsgNoLookups=true"</code></li>
-<li>(Windows) Edit your <code>solr.in.cmd</code> file to include:
- <code>set SOLR_OPTS=%SOLR_OPTS% -Dlog4j2.formatMsgNoLookups=true</code></li>
-<li>Follow any of the other mitgations listed at <a href="https://logging.apache.org/log4j/2.x/security.html">https://logging.apache.org/log4j/2.x/security.html</a></li>
-</ul>
-<p>The Log4J security page refers to setting <code>log4j2.formatMsgNoLookups=true</code> as a "discredited" mitigation. In reality, it depends.
-We've looked at the root cause and audited the code paths that lead to the vulnerability, and we feel confident in this mitigation being sufficient for Solr.
-See <a href="https://lists.apache.org/thread/kgh63sncrsm2bls884pg87mnt8vqztmz">https://lists.apache.org/thread/kgh63sncrsm2bls884pg87mnt8vqztmz</a> for discussion.</p>

-<p><strong>Versions Affected:</strong>
-7.0.0 to 7.7.3

-<p><strong>Description:</strong>
-The ReplicationHandler (normally registered at "/replication" under a Solr core) has a "masterUrl" (also "leaderUrl" alias) parameter that is used to designate another ReplicationHandler on another Solr core to replicate index data into the local core.
-To prevent a SSRF vulnerability, Solr ought to check these parameters against a similar configuration it uses for the "shards" parameter. Prior to this bug getting fixed, it did not.</p>
-<p><strong>Mitigation:</strong>
-Any of the following are enough to prevent this vulnerability:</p>
-<ul>
-<li>Upgrade to <code>Solr 8.8.2</code> or greater.</li>
-<li>If upgrading is not an option, consider applying the patch in <a href="https://issues.apache.org/jira/browse/SOLR-15217">SOLR-15217</a></li>
-<li>Ensure that any access to the replication handler is purely internal to Solr. Typically, it's only accessed externally for diagnostic/informational purposes.</li>

-<p><strong>Description:</strong>
-Reported in SOLR-14515 (private) and fixed in SOLR-14561 (public), released in Solr version 8.6.0.
-The Replication handler (https://solr.apache.org/guide/8_6/index-replication.html#http-api-commands-for-the-replicationhandler) allows commands backup, restore and deleteBackup. Each of these take a location parameter, which was not validated, i.e you could read/write to any location the solr user can access. </p>
-<p>On a windows system SMB paths such as \10.0.0.99\share\folder may also be used, leading to:</p>
-<ul>
-<li>The possibility of restoring another SolrCore from a server on the network (or mounted remote file system) may lead to:<ul>
-<li>Exposing search index data that the attacker should otherwise not have access to</li>
-<li>Replacing the index data entirely by loading it from a remote file system that the attacker controls</li>
-</ul>
-</li>
-<li>Launching SMB attacks which may result in:<ul>
-<li>The exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes),</li>
-<li>In case of misconfigured systems, SMB Relay Attacks which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution </li>

-response writer with that setting set to <code>true</code>. Defining a response
-writer requires configuration API access.</p>
-<p>Solr 8.4 removed the params resource loader entirely, and only enables the
-configset-provided template rendering when the configset is <code>trusted</code> (has
-been uploaded by an authenticated user).</p>
-<p><strong>Mitigation:</strong><br>
-Ensure your network settings are configured so that only trusted traffic
-communicates with Solr, especially to the configuration APIs.</p>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong><br>
-Solr 8.1.1 and 8.2.0 for Linux</p>
-<p><strong>Description:</strong><br>
-The 8.1.1 and 8.2.0 releases of Apache Solr contain an
-insecure setting for the ENABLE_REMOTE_JMX_OPTS configuration option
-in the default solr.in.sh configuration file shipping with Solr.</p>
-<p>Windows users are not affected.</p>
-<p>If you use the default solr.in.sh file from the affected releases, then
-JMX monitoring will be enabled and exposed on RMI_PORT (default=18983),
-without any authentication. If this port is opened for inbound traffic
-in your firewall, then anyone with network access to your Solr nodes
-will be able to access JMX, which may in turn allow them to upload
-malicious code for execution on the Solr server.</p>
-<p>The vulnerability is already public [1] and mitigation steps were
-announced on project mailing lists and news page [3] on August 14th,
-without mentioning RCE at that time.</p>
-<p><strong>Mitigation:</strong><br>
-Make sure your effective solr.in.sh file has ENABLE_REMOTE_JMX_OPTS set
-to 'false' on every Solr node and then restart Solr. Note that the
-effective solr.in.sh file may reside in /etc/defaults/ or another
-location depending on the install. You can then validate that the
-'com.sun.management.jmxremote*' family of properties are not listed in
-the "Java Properties" section of the Solr Admin UI, or configured in a
-secure way.</p>
-<p>There is no need to upgrade or update any code.</p>
-<p>Remember to follow the Solr Documentation's advice to never expose Solr
-nodes directly in a hostile network environment.</p>

-</ul>
-<p><strong>Description:</strong><br>
-The DataImportHandler, an optional but popular module to pull in data from
-databases and other sources, has a feature in which the whole DIH
-configuration can come from a request's "dataConfig" parameter. The debug
-mode of the DIH admin screen uses this to allow convenient debugging /
-development of a DIH config. Since a DIH config can contain scripts, this
-parameter is a security risk. Starting with version 8.2.0 of Solr, use of
-this parameter requires setting the Java System property
-<code>enable.dih.dataConfigParam</code> to true.</p>
-<p><strong>Mitigation:</strong> </p>
-<ul>
-<li>Upgrade to 8.2.0 or later, which is secure by default.</li>
-<li>or, edit solrconfig.xml to configure all DataImportHandler usages with an "invariants" section listing the "dataConfig" parameter set to am empty string.</li>
-<li>Ensure your network settings are configured so that only trusted traffic communicates with Solr, especially to the DIH request handler. This is a best practice to all of Solr.</li>

-<p><strong>Description:</strong><br>
-The details of this vulnerability were reported to the Apache Security mailing list. </p>
-<p>This vulnerability relates to an XML external entity expansion (XXE) in the
-<code>&amp;dataConfig=&lt;inlinexml&gt;</code> parameter of Solr's DataImportHandler. It can be
-used as XXE using file/ftp/http protocols in order to read arbitrary local
-files from the Solr server or the internal network. See [1] for more details.</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 6.6.3 or Solr 7.3.0 releases both
-of which address the vulnerability. Once upgrade is complete, no other steps
-are required. Those releases disable external entities in anonymous XML files
-passed through this request parameter. </p>
-<p>If users are unable to upgrade to Solr 6.6.3 or Solr 7.3.0 then they are
-advised to disable data import handler in their solrconfig.xml file and
-restart their Solr instances. Alternatively, if Solr instances are only used
-locally without access to public internet, the vulnerability cannot be used
-directly, so it may not be required to update, and instead reverse proxies or
-Solr client applications should be guarded to not allow end users to inject
-<code>dataConfig</code> request parameters. Please refer to [2] on how to correctly
-secure Solr servers.</p>

-The Apache Software Foundation</p>
-<p><strong>Versions Affected:</strong></p>
-<ul>
-<li>Solr 5.0.0 to 5.5.4</li>

-<p><strong>Description:</strong><br>
-Apache Solr uses Apache Tika for parsing binary file types such as
-doc, xls, pdf etc. Apache Tika wraps the jmatio parser
-(https://github.com/gradusnikov/jmatio) to handle MATLAB files. The
-parser uses native deserialization on serialized Java objects embedded
-in MATLAB files. A malicious user could inject arbitrary code into a
-MATLAB file that would be executed when the object is deserialized.</p>
-<p>This vulnerability was originally described at
-http://mail-archives.apache.org/mod_mbox/tika-user/201611.mbox/%3C2125912914.1308916.1478787314903%40mail.yahoo.com%3E</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 5.5.5 or Solr 6.6.2 or Solr 7.1.0
-releases which have fixed this vulnerability.</p>
-<p>Solr 5.5.5 upgrades the jmatio parser to v1.2 and disables the Java
-deserialisation support to protect against this vulnerability.</p>
-<p>Solr 6.6.2 and Solr 7.1.0 have upgraded the bundled Tika to v1.16.</p>
-<p>Once upgrade is complete, no other steps are required.</p>

-<li>Solr 7.0.0 to 7.0.1</li>
-</ul>
-<p><strong>Description:</strong><br>
-The details of this vulnerability were reported on public mailing
-lists. See https://s.apache.org/FJDl</p>
-<p>The first vulnerability relates to XML external entity expansion in
-the XML Query Parser which is available, by default, for any query
-request with parameters deftype=xmlparser. This can be exploited to
-upload malicious data to the /upload request handler. It can also be
-used as Blind XXE using ftp wrapper in order to read arbitrary local
-files from the solr server.</p>
-<p>The second vulnerability relates to remote code execution using the
-RunExecutableListener available on all affected versions of Solr.</p>
-<p>At the time of the above report, this was a 0-day vulnerability with a
-working exploit affecting the versions of Solr mentioned in the
-previous section. However, mitigation steps were announced to protect
-Solr users the same day. See
-https://solr.apache.org/news.html#12-october-2017-please-secure-your-apache-solr-servers-since-a-zero-day-exploit-has-been-reported-on-a-public-mailing-list</p>
-<p><strong>Mitigation:</strong><br>
-Users are advised to upgrade to either Solr 6.6.2 or Solr 7.1.0
-releases both of which address the two vulnerabilities. Once upgrade is
-complete, no other steps are required.</p>
-<p>If users are unable to upgrade to Solr 6.6.2 or Solr 7.1.0 then they
-are advised to restart their Solr instances with the system parameter
-<code>-Ddisable.configEdit=true</code>. This will disallow any changes to be made
-to your configurations via the Config API. This is a key factor in
-this vulnerability, since it allows GET requests to add the
-RunExecutableListener to your config. Users are also advised to re-map
-the XML Query Parser to another parser to mitigate the XXE
-vulnerability. For example, adding the following to the solrconfig.xml
-file re-maps the xmlparser to the edismax parser:
-<code>&lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&gt;</code></p>

-<p>Here is what we're recommending and what we're doing now:</p>
-<ul>
-<li>
-<p>Until fixes are available, all Solr users are advised to restart their
-Solr instances with the system property <code>-Ddisable.configEdit=true</code>.
-This will disallow any changes to be made to configurations via the
-Config API. This is a key factor in this vulnerability, since it allows
-GET requests to add the RunExecutableListener to the config. This is
-sufficient to protect you from this type of attack, but means you cannot
-use the edit capabilities of the Config API until the other fixes
-described below are in place. Users are also advised to remap
-the XML Query Parser to another parser to mitigate the XXE
-vulnerability. For example, adding the following to the solrconfig.xml
-file maps the <code>xmlparser</code> to the <code>edismax</code> parser:
-<code>&lt;queryParser name="xmlparser" class="solr.ExtendedDismaxQParserPlugin"/&gt;</code>.</p>
-</li>
-<li>
-<p>A new release of Lucene/Solr was in the vote phase, but we have now
-pulled it back to be able to address these issues in the upcoming 7.1
-release. We will also determine mitigation steps for users on earlier
-versions, which may include a 6.6.2 release for users still on 6.x.</p>
-</li>
-<li>
-<p>The RunExecutableListener will be removed in 7.1. It was previously
-used by Solr for index replication but has been replaced and is no
-longer needed.</p>
-</li>
-<li>
-<p>The XML Parser will be fixed and the fixes will be included in the 7.1
-release.</p>
-</li>
-<li>
-<p>The 7.1 release was already slated to include a change to disable the
-<code>stream.body</code> parameter by default, which will further help protect
-systems.</p>

-<p><strong>Description</strong>:</p>
-<p>Solr's Kerberos plugin can be configured to use delegation tokens, which allows an application to reuse the authentication of an end-user or another application.
-There are two issues with this functionality (when using SecurityAwareZkACLProvider type of ACL provider e.g. SaslZkACLProvider),</p>
-<p>Firstly, access to the security configuration can be leaked to users other than the solr super user. Secondly, malicious users can exploit this leaked configuration for privilege escalation to further expose/modify private data and/or disrupt operations in the Solr cluster.</p>

-</ul>
-<p><strong>Description:</strong><br>
-Solr uses a PKI based mechanism to secure inter-node communication
-when security is enabled. It is possible to create a specially crafted
-node name that does not exist as part of the cluster and point it to a
-malicious node. This can trick the nodes in cluster to believe that
-the malicious node is a member of the cluster. So, if Solr users have
-enabled BasicAuth authentication mechanism using the BasicAuthPlugin
-or if the user has implemented a custom Authentication plugin, which
-does not implement either "HttpClientInterceptorPlugin" or
-"HttpClientBuilderPlugin", his/her servers are vulnerable to this
-attack. Users who only use SSL without basic authentication or those
-who use Kerberos are not affected.</p>
