CVE-2026-10064Public exploitNetwork attack vector

Authenticated code execution via unchecked special_name copy

Published May 29, 2026 · Updated May 29, 2026

Stack overflow in TRENDnet TEW-432BRP 3.10B20 allows remote authenticated users to execute code via a crafted HTTP request. The boa binary's formSetPortTr handler copies the unbounded special_name parameter into a stack local, overwriting the function return address. Router management credentials are required; the published proof of concept demonstrates a persistent service crash, while return-address control enables arbitrary code execution.
