CVE-2024-41465Public exploitNetwork attack vector

Router crash via unchecked funcpara1 stack copy

Published Jul 24, 2024 · Updated Aug 2, 2024

A stack-based buffer overflow in Tenda FH1201 Firmware 1.2.0.14 allows remote attackers to crash the router via an HTTP request. The setcfm function passes attacker-controlled funcpara1 data to sprintf, which copies it into stack buffer v10 without checking its length. Network reachability is required, but authentication and user interaction are not; the demonstrated consequence is service interruption.
