Arnout Engelen commented on XERCESJ-1756:
-----------------------------------------
Unfortunately [https://blogs.securiteam.com/index.php/archives/3271] is no
longer up (and not available on archive.org), but the discussion in
[https://github.com/jeremylong/DependencyCheck/issues/4614] suggests this may
have to do with {{XMLEntityManager.setupCurrentEntity()}} not having a timeout.
[https://github.com/OSSIndex/vulns/issues/328#issuecomment-1287175491] also
mentions this.
[https://www.exploit-db.com/exploits/44057] describes two issues, one generic
and one specific to Xerces-j.
[https://security.snyk.io/vuln/SNYK-JAVA-XERCES-31497] leads by describing the
FTP problem, then confusingly continues with a generic unrelated description of
ReDOS attacks. It claims xerces-j 2.11.0 is no longer affected.
TBH I'm somewhat sceptical of this whole issue - when processing untrusted
input shouldn't people be disabling loading external entities anyway?
