CVE-2018-25139Public exploitNetwork attack vector

Unauthenticated live-stream disclosure via RTSP endpoint

Published Dec 24, 2025 · Updated Dec 24, 2025

Missing authentication in FLIR AX8 1.32.16 allows remote attackers to view and record live thermal video over RTSP. The /mpeg4 RTSP endpoint serves the camera's live stream to unauthenticated client connections instead of requiring credentials. Network reachability to the camera is the only reported gate; the disclosed behavior exposes footage but does not alter device configuration.
