CVE-2018-14558 is a command injection vulnerability affecting Tenda AC7 devices with firmware through V15.03.06.44_CN, AC9 devices with firmware through V15.03.05.19(6318)_CN, and AC10 devices with firmware through V15.03.06.23_CN. The flaw is exposed through the goform/setUsbUnload web request handler. In the vulnerable code path, the formsetUsbUnload function passes attacker-controlled input to a dosystemCmd function without adequate sanitization or neutralization of shell metacharacters, allowing arbitrary operating system commands to be executed on the device.
