CVE-2022-47117Public exploitNetwork attack vector

Unauthenticated memory corruption via security parameter

Published Dec 30, 2022 · Updated Apr 11, 2025

Stack overflow in Tenda A15 15.13.07.13 allows remote attackers to corrupt memory via the security parameter in /goform/WifiBasicSet. The public disclosure identifies the handler and parameter but does not publish the copy operation or destination-buffer dimensions that produce the overflow. The interface is network-reachable without privileges or user interaction; successful triggering corrupts memory, while public sources document no demonstrated crash or code-execution path.
