MERCURY MIPC252W IP camera v1.0.5 Build 230306 Rel.79931n does not implement nonce expiration in RTSP Digest authentication. An adjacent network attacker can capture a legitimate authentication exchange and replay the nonce and response values in a new connection to bypass authentication without knowledge of the device credentials, gaining unauthorized access to the live video stream.
