## Technical details

A stack-based buffer overflow exists in the 'boa' binary of the TRENDnet TEW-432BRP router, specifically within the 'formResetStatistic' function in the '/goform/formResetStatistic' file. The vulnerability is caused by a lack of bounds checking on the 'status_statistic' (or 'webpage' as seen in PoC) parameter, which is copied directly into a local stack variable. A remote attacker with low privileges can exploit this by sending a specially crafted POST request with an oversized argument, overwriting the function's return address to achieve arbitrary code execution or a device crash. The vendor has confirmed this product is end-of-life (EOL) and no patch will be released.
