Summary

TP-Link Tapo C325WB v2 versions before V2_1.3.3 Build 260914 are affected when the Camera Account feature is enabled. Crafted RTSP-over-HTTP tunneling requests corrupt memory in the RTSP streaming service on TCP port 554 through a stack-based buffer overflow (CWE-121). An unauthenticated attacker on an adjacent network can crash the streaming daemon and disrupt live video until the service recovers or restarts.

Description from the CNA

An 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.
