versionCompletePBX <= 5.2.35
  • Monitor for command injection attempts targeting the Task Scheduler functionality in Xorcom CompletePBX's administrator interface, specifically looking for unsanitized user-controlled input being passed to system commands.
  • Alert on exploitation attempts originating from the 'admin' (superadmin) account specifically, as only this account has the necessary permissions to trigger the vulnerability — lower-privileged accounts cannot exploit it.
  • Monitor for processes spawned as root from the CompletePBX web server process, which may indicate successful command injection via the Task Scheduler.
  • ·Exploitation requires authentication as the 'admin' superadmin account; standard privileged users cannot trigger the vulnerability, so detections should be scoped accordingly.
  • ·All CompletePBX versions up to and including 5.2.35 are affected; ensure patching to versions beyond 5.2.35 to remediate.
