Description

A denial-of-service vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP request path parsing logic. The implementation enforces length restrictions on the raw request path but does not account for path expansion performed during normalization. An attacker on the adjacent network may send a crafted HTTP request to cause buffer overflow and memory corruption, leading to system interruption or device reboot.

Weakness classification

  • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
