HIGH

TP-Link Tapo C210 v3 C220 v1 C520WS v2 - Unauthenticated Denial of Service via Long URL Path

Title source: llm
STIX 2.1

Description

The HTTP parser of Tapo C210 v3, C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An unauthenticated attacker can force repeated service crashes or device reboots, causing denial of service.
