CVE-2022-46109Public exploitNetwork attack vector

Router crash via unchecked speed parameter formatting

Published Dec 16, 2022 · Updated Apr 17, 2025

A stack-based buffer overflow in Tenda AC15 15.03.06.23 allows remote attackers to crash the router through a crafted HTTP request. The formSetClientState handler formats user-controlled speed fields with sprintf without checking their lengths, overflowing a stack buffer. The linked proof of concept targets AC10 rather than AC15, so the detailed mechanism has not been independently verified on the product named by the CVE record.
