Description Andrej Nemec 2016-12-21 14:34:42 UTC

Apache CXF JAX-RS implementation provides a number of Atom MessageBodyReaders. These readers use Apache Abdera Parser to parse Atom feeds or Entries, with this Parser expanding XML entities by default. This represents a major XXE risk.

Comment 1 Andrej Nemec 2016-12-21 14:35:32 UTC

Created cxf tracking bugs for this issue:

Affects: fedora-all [bug 1406813]

Comment 5 Jason Shepherd 2016-12-22 05:25:40 UTC

JBoss EAP 6 and 7 implement JAX-RS using Resteasy, not CXF. Therefore the vulnerable AbstractAtomProvider class is not part of either distribution. Setting EAP 6 and 7 layered productgs as not affected.
