Unauthenticated router crash via stack buffer overwrite
Published Jan 16, 2025 · Updated Mar 19, 2025
Stack overflow in Tenda AC18 firmware 15.03.05.19 allows remote attackers to crash the router via a crafted limitSpeedUp value. The formSetClientState handler passes the POST parameter directly to sprintf, which writes it into a fixed-size local stack buffer and permits return-address overwrite. No authentication or user interaction is required; the demonstrated consequence is a device crash, while return-address control exposes code-execution risk.
