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.
