DescriptionAn unauthenticated denial-of-service vulnerability exists in Tapo C325WB v2 in the RTSP streaming service on TCP port 554 when the Camera Account feature is enabled. A crafted pair of RTSP-over-HTTP tunneling requests can cause memory corruption and crash the streaming daemon.  Successful exploitation may allow an unauthenticated adjacent-network attacker to disrupt live video and related streaming functions until the affected service recovers or restarts.
