Chris M. Hostetter updated SOLR-14844:
--------------------------------------
Description:
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.-
In normal Solr installs, w/o jetty optimizations, this issue is largely
mitigated in 8.6.3: see SOLR-14896 (and linked bug fixes) for details.
