Description

A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 in the HTTP POST body parsing logic due to missing validation of remaining buffer capacity after dynamic allocation, due to insufficient boundary validation when handling externally supplied HTTP input.  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.
