An attacker on the adjacent network can disrupt camera operation, disabling monitoring and potentially causing loss of recordings.
Recommendation
Contact the vendor for a patch or consider restricting device access to trusted networks.
Original NVD description (English source)
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.
