| Title | TRENDnet TEW-811DRU 1.0.4.0 OS Command Injection |
|---|
| Description | Trendnet TEW-815DAP firmware version x.x.x.x contains an authenticated command injection vulnerability in the setDeviceURL function. The vulnerability stems from insufficient input sanitization where the DeviceURL parameter is directly concatenated into a shell command executed via system(). Although the backend implements a blacklist to filter characters like ;, &, and `, it fails to block pipes (|) or command substitution ($()). An attacker can exploit this by logging in, extracting the hidden CSRF token from the web interface (e.g., /wizard/wizard.asp), and sending a crafted POST request to /uapply.cgi, allowing for arbitrary command execution with root privileges. |
