Impact

The profile location routine in the referencevalidator commons package is vulnerable to XML External Entities attack due to insecure defaults of the used Woodstox WstxInputFactory. A malicious XML resource can lead to network requests issued by referencevalidator and thus to a Server Side Request Forgery attack.

The vulnerability impacts applications which use referencevalidator to process XML resources from untrusted sources.

Patches

The problem has been patched with the 2.5.1 version of the referencevalidator. Users are strongly recommended to update to this version or a more recent one.

Workarounds

A pre-processing or manual analysis of input XML resources on existence of DTD definitions or external entities can mitigate the problem.
