Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS

A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the asynchronous parsing of local video stream content due to

insufficient alignment and validation of buffer boundaries when processing streaming inputs.An attacker

on the same network segment could trigger heap memory corruption conditions by

sending crafted payloads that cause write operations beyond allocated buffer

boundaries.  Successful exploitation

causes a Denial-of-Service (DoS) condition, causing the device’s process to

crash or become unresponsive.
