----------------------------------------

             Summary: Upgrade Jetty to 9.4.30+
                 Key: SOLR-14844
                 URL: https://issues.apache.org/jira/browse/SOLR-14844
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 8.6
            Reporter: Cassandra Targett


A CVE was found in Jetty 9.4.27-9.4.29 that has some security scanning tools raising red flags (https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-17638).

Here's the Jetty issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=564984. It's fixed in 9.4.30+, so we should upgrade to that for 8.7

It has a simple mitigation (raise Jetty's responseHeaderSize to higher than requestHeaderSize), but I don't know how Solr uses Jetty well enough to a) know if this problem is even exploitable in Solr, or b) if the workaround suggested is even possible in Solr.
