Senserva AI Opinion for CVE-2018-14667

Red Hat JBoss RichFaces has an expression language injection in the UserResource endpoint that a remote, unauthenticated attacker can convert into code execution using chained Java serialized objects. RichFaces is a discontinued framework baked into many aging Java web apps, so the fix is usually migration rather than a patch, which is why exploitation continued long enough for a 2023 KEV listing. Critical Severity at CVSS 9.8 with a 74 percent EPSS score.

Do this: Scan Java applications for bundled RichFaces libraries and firewall or retire any app still serving its resource endpoints.
