Vulnerability Description

A null pointer dereference vulnerability exists in the RTSP service of the MERCURY MIPC252W 1.0.5 Build 230306 Rel.79931n. During the processing of a SETUP request for the path rtsp://<IP>:554/stream1/track2, the device fails to properly validate the Transport header field. When this header is improperly constructed, the RTSP service can dereference a NULL pointer during request parsing. Successful exploitation causes the device to crash and automatically reboot.
