## Technical details

A command injection vulnerability exists in the TRENDnet TEW-432BRP router (firmware version 3.10B20) within the 'formSysCmd' function of the '/goform/formSysCmd' endpoint. The 'sysCmd' parameter is passed directly to the underlying operating system without sufficient sanitization or validation. A remote attacker with low privileges (authenticated access) can exploit this by sending a specially crafted POST request to execute arbitrary shell commands on the device. The vendor has stated that no fix will be released as the product has been end-of-life (EOL) since 2009.
