Authenticated router crash via unchecked stack copy
Published May 31, 2026 · Updated May 31, 2026
Stack-based buffer overflow in TRENDnet TEW-432BRP 3.10B20 allows remote authenticated users to crash the router via an HTTP request. The boa formSetEnableWizard handler copies the attacker-controlled webpage field directly into a stack local without a length check, overwriting the return address. Low-privileged access to the web-management interface is required; the published proof of concept demonstrates a persistent service failure, while arbitrary code execution is claimed but not demonstrated.
