CVE-2025-29030Public exploitNetwork attack vector

Unauthenticated router crash via unchecked WPS input

Published Mar 14, 2025 · Updated Mar 19, 2025

Buffer overflow in Tenda AC6 firmware 15.03.05.16 allows remote attackers to crash the router via a crafted WPS request. The formWifiWpsOOB handler passes the attacker-controlled index value to sprintf, which copies it into a four-byte destination without a bounds check. No authentication or user interaction is required, and the published evidence demonstrates a crash rather than code execution.
