Vulnerability Title
Denial of Service via Path Expansion Overflow in HTTP Service in TP-Link Tapo C520WS
Source: NVD (National Vulnerability Database)
Vulnerability 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.
