snort
48067 - 48068
  • Detect exploitation attempts by monitoring for HTTP packets containing multiple 'Accept:' header strings targeting the RTSP-over-HTTP tunnel port(s), which trigger a stack buffer overflow in the 'lookForHeader' function.
  • Detect exploitation attempts by monitoring for HTTP packets containing multiple 'x-sessioncookie' header strings targeting the RTSP-over-HTTP tunnel port(s).
  • Focus inspection on the RTSP-over-HTTP tunneling functionality; the vulnerable code path is only reachable when an HTTP client negotiates the RTSP-over-HTTP tunnel on the bound HTTP port.
  • ·Snort rules 48067-48068 are subject to change; always pull the latest rule definitions from Firepower Management Center or Snort.org for current coverage.
  • ·The vulnerability is confirmed in version 0.92 but may also be present in earlier versions; scope detection/patching accordingly.
