Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CVE-2018-14667
CriticalCVSS 9.8KEVSummary
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.
Risk Assessment
This vulnerability allows remote code execution without authentication, potentially leading to full compromise of the application server and breach of confidentiality, integrity, and availability.
Recommendation
Update RichFaces Framework to a version later than 3.3.4 or apply available security patches. If updating is not possible, consider disabling or restricting access to the UserResource.
