CVE-2022-45505Public exploitNetwork attack vector

Router crash via unchecked cmdinput stack copy

Published Dec 8, 2022 · Updated Apr 23, 2025

Stack overflow in Tenda W30E 1.0.1.25(633) allows remote attackers to crash the router via cmdinput sent to /goform/exeCommand. The exeCommand handler passes the unbounded cmdinput value to strcpy, which copies it into a fixed-size stack destination named s without a size check. No authentication or user interaction is required; the demonstrated and scored consequence is a router crash, not confidentiality or integrity loss.
