Technical details
An OS command injection vulnerability exists in the TRENDnet TEW-821DAP firmware version 1.11B03 within the 'ssi' binary. The flaw is located in function sub_43F2C4, which handles DNS lookup requests via the /goform/tools_nslookup endpoint. The application fails to sanitize the 'nslookup_target' and 'dns_server' POST parameters before passing them to a sprintf call that constructs a system command (e.g., "nslookup %s %s"). An authenticated attacker can inject shell metacharacters into these parameters to execute arbitrary code with the privileges of the web server. The vendor has stated the product is End-of-Life (EOL) and will not be patched.
