Router crash via unchecked sprintf in CertListInfo

Published Dec 8, 2022 · Updated Apr 23, 2025

Stack overflow in Tenda W30E 1.0.1.25(633) allows remote authenticated users to crash the router via a crafted CertListInfo request. The handler passes an oversized name value to sprintf without a size check when downaction is selected, overflowing a stack buffer. The published proof of concept authenticates as an administrator before sending the request; the demonstrated consequence is a router crash.
