Technical details
A stack-based buffer overflow vulnerability exists in the 'boa' binary of the TRENDnet TEW-432BRP router, specifically within the 'formSysLog' function handled via the '/goform/formSysLog' endpoint. The vulnerability is triggered by a lack of bounds checking on the 'current_page' (or 'webpage' as noted in PoC) parameter, which is copied directly into a local stack variable. A remote attacker with low privileges (authenticated access) can exploit this by sending a POST request with an oversized string, leading to the overwriting of the function's return address. This can result in a persistent denial of service (device crash) or remote code execution. No patch is available as the device has been EOL since 2009.
