CVE-2025-7463Public exploitNetwork attack vector

Authenticated code execution via unbounded mit_ssid formatting

Published Jul 12, 2025 · Updated Jul 14, 2025

Buffer overflow in Tenda FH1201 1.2.0.14 allows remote authenticated users to execute code or crash the router via a crafted mit_ssid value. The formWrlsafeset handler passes the user-controlled mit_ssid value to sprintf without a length check, overflowing stack buffer s_1. Access to the network-reachable management interface and valid low-privilege authentication are required; successful exploitation permits code execution or a service crash.
