CVE-2018-14667
Red Hat JBoss RichFaces Framework Expression Language Injection Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 19 October 2023). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
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.
