Technical details

A stack-based buffer overflow exists in the 'ssi' component of TRENDnet TEW-821DAP firmware version 1.12B01. The vulnerability is located in function sub_41EC14 within the /goform/tools_nslookup handler. The root cause is an insufficient buffer allocation (2 bytes) for a command string that is at least 33 bytes long ("nslookup ${host} > /tmp/nslookup"). An authenticated remote attacker can trigger this overflow by sending an HTTP POST request to the affected endpoint. Successful exploitation could lead to remote code execution (RCE) or a device crash. The vendor has stated the product is End-of-Life (EOL) and will not be patched.
