CVE-2018-14667JBoss RichFaces — an expression evaluated from a request

The RichFaces framework, versions 3.0 through 3.3.4, evaluates an expression taken from a request, so an attacker with no credentials chains serialized objects into code execution on the server.

YOUR NEXT MOVE

Move applications off RichFaces 3.x. That branch is unmaintained, so the real remedy is the framework upgrade or removing the affected resource handler outright.
