## Technical details

A stack-based buffer overflow vulnerability exists in the 'formWlanSetup' function within the '/goform/formWlanSetup' endpoint of the TRENDnet TEW-432BRP router (firmware 3.10B20). The 'enrollee' POST parameter is copied into a local stack variable without adequate bounds checking. A remote attacker with low privileges (authenticated access to the web interface) can provide an oversized string to overwrite the return address, leading to arbitrary code execution or a device crash (DoS). A public exploit is available. The vendor has stated that no patch will be released as the product has been End-of-Life (EOL) since 2009.
