----------------------------------
Summary: Upgrade Jetty to 9.4.31 (was: Upgrade Jetty to 9.4.30+)
> Upgrade Jetty to 9.4.31
> -----------------------
>
> 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
> Assignee: Erick Erickson
> Priority: Major
>
> 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.
