Title

RTSP Null Pointer Dereference Denial-of-Service Vulnerability on TP-Link Tapo C100 and C101

Summary

Tapo C100/C101 V5 contains a null pointer dereference vulnerability in the RTSP service. An attacker on the local network can send specially crafted requests that cause the service to dereference an invalid pointer, resulting in a service crash and device reboot. Successful exploitation can disrupt live video streaming functionality and cause a temporary denial-of-service condition.

Severity
