  • Exploit vector targets MediaOutputResource's resource request endpoint to inject an arbitrary EL variable mapper for RCE
  • This vulnerability bypasses the previously applied mitigation for CVE-2015-0279 via EL variable mapper injection; detection logic should account for both CVEs in RichFaces 4.5.3–4.5.17
  • Technical write-up with exploitation details available at the Code White Sec blog — review for payload patterns and request signatures
  • ·Affected versions are RichFaces 4.5.3 through 4.5.17 only; earlier and later versions are not confirmed vulnerable
