command{"oldPassword":"KAKA","newPassword":"ZULU`sleep 7`"}
  • Detect command injection attempts in the 'newPassword' field of the password-change API endpoint — look for backtick-enclosed shell commands (e.g., `sleep N`) in JSON POST bodies targeting ABB FLXeon devices.
  • Monitor for HTTP requests carrying the 'user_sid' session cookie to FLXeon management interfaces, particularly when accompanied by JSON payloads containing shell metacharacters (backticks, semicolons, pipes).
  • CVE-2024-48841 is a network-exploitable command injection (CWE-77) with CVSS v4 10.0 and no authentication required (PR:N, UI:N) — prioritize detection on any internet-exposed FLXeon device running firmware 9.3.4 or prior.
  • ·The unauthenticated RCE exploit (52186) uses a hardcoded test password 'KAKA' in the oldPassword field; real-world attacks will use valid credentials or exploit the pre-auth path — do not rely solely on this string for detection.
  • ·The 'user_sid=xxx' cookie value in the PoC exploits is a placeholder; actual sessions will have a real session ID value — detection rules should match on the cookie name 'user_sid' rather than the literal value 'xxx'.
  • ·ABB states these vulnerabilities are only exploitable if attackers can access the network segment where FLXEON is installed and exposed directly to the internet — scope detection accordingly to internet-facing or improperly segmented deployments.
