Description
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP parsing loop when appending segmented request bodies without continuous write‑boundary verification, 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.
