Official description
Tenda CP3 V3.0 firmware V31.1.9.91 contains a stack-based buffer overflow in the RTSP service.

An unauthenticated remote attacker who has completed a standard RTSP session handshake can send a PLAY request with an excessively long clock= value to cause the RTSP service to crash.
