Tapo C100/C101 V5 contains a heap-based buffer overflow vulnerability in the RTSP service. An authenticated attacker on the local network can send specially crafted RTSP frame data containing oversized length values, resulting in out-of-bounds heap writes. Successful exploitation can crash the RTSP service and trigger a device reboot, resulting in a temporary denial-of-service condition.
