| Title | Tenda AC10 Tenda AC10 V1.0 Router V15.03.06.23_multi_TD01 Command Injection |
|---|
| Description | Tenda AC10 V1.0 Router is a consumer-grade wireless router supporting advanced wireless features, firewall, and device management capabilities. A command injection vulnerability exists in the formWriteFacMac function, which handles requests to the /goform/WriteFacMac endpoint. Attackers can inject arbitrary system commands via the mac parameter, leading to unauthorized device control or complete compromise.
The formWriteFacMac function processes POST requests to /goform/WriteFacMac. It extracts the user-controlled mac parameter using websGetVar and passes it directly to doSystemCmd without sanitization. In doSystemCmd, the parameter is interpolated into a system command (e.g., cfm mac %s) and executed directly on the system. By injecting special characters (e.g., ;), attackers can escape the command context and execute arbitrary system commands on the router.
