Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability resides in TMUI (Configuration utility / Traffic Management User Interface) on BIG-IP; monitor for authenticated remote command execution attempts targeting undisclosed TMUI pages
  • Scope detection to BIG-IP versions 11.6.1–11.6.5.3, 12.1.0–12.1.5.3, 13.1.0–13.1.3.6, 14.1.0–14.1.4, 15.1.0–15.1.2.1, and 16.0.0–16.0.1.1 as confirmed vulnerable ranges
  • ·Exploitation requires prior authentication; unauthenticated access alone is insufficient to trigger this RCE vulnerability
  • ·The specific vulnerable TMUI pages are not disclosed by F5; detection must rely on broad TMUI access monitoring rather than targeting specific endpoints
  • ·BIG-IP versions that have reached End of Software Development (EoSD) are not evaluated and may also be vulnerable but are out of scope for F5 patching
