[jira] (SOLR-16777) Schema Designer blindly "trusts" potentially malicious configset
[ https://issues.apache.org/jira/browse/SOLR-16777 ]

{quote}I think the code should be determining if the user is trusted and then passing the correct value.

Actually no. We deliberately made this choice not to allow untrusted features for configsets uploaded though API

> When configset API is used to upload configsets by unauthenticated users, a "trusted: false" flag is set on the configset. Such configsets cannot use the <lib> directive to load classes while creating/loading collections. Details here: https://solr.apache.org/guide/8_10/configsets-api.html#configsets-upload
> Unfortunately, this safety mechanism was bypassed in the schema designer when a isConfigsetTrusted was hardcoded to true. [https://github.com/apache/solr/blob/branch_9_1/solr/core/src/java/org/apache/solr/handler/designer/SchemaDesignerConfigSetHelper.java#L697]

> As per Skay's report [https://twitter.com/Skay_00/status/1646870062601756672|https://twitter.com/Skay_00/status/1646870062601756672),] remote code execution is possible in unsecured Solr clusters where authentication hasn't been enabled. This ticket is to mitigate one aspect of that, i.e. the schema designer vulnerability. While our recommendation to all users remains the same, i.e. to secure Solr installations with authentication and authorization, I thank Skay for his detailed report.
