Required action. Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Description

The RichFaces Framework 3.X through 3.3.4 is vulnerable to Expression Language (EL) injection via the UserResource resource. A remote, unauthenticated attacker could exploit this to execute arbitrary code using a chain of java serialized objects via org.ajax4jsf.resource.UserResource$UriData.
