Technical details

A stack-based buffer overflow vulnerability exists in the 'boa' binary of the TRENDnet TEW-432BRP router, specifically within the 'formWPS' function located at '/goform/formWPS'. The vulnerability is caused by a lack of bounds checking on the 'peerPin' POST parameter, which is copied directly into a local stack variable. A remote attacker with low privileges (authenticated access) can provide an excessively long string to overwrite the function's return address, leading to arbitrary code execution or a device crash (DoS). The vendor has stated that no patch will be issued as the product has been end-of-life (EOL) since 2009.
