Descriptions

An issue was discovered on Tenda AC7 devices with firmware through V15.03.06.44_CN(AC7), AC9 devices with firmware through V15.03.05.19(6318)_CN(AC9), and AC10 devices with firmware through V15.03.06.23_CN(AC10). A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted goform/setUsbUnload request. This occurs because the "formsetUsbUnload" function executes a dosystemCmd function with untrusted input.

Se ha descubierto un problema en dispositivos Tenda AC7 con firmware hasta la versión V15.03.06.44_CN(AC7), dispositivos AC9 devices con firmware hasta la versión V15.03.05.19(6318)_CN(AC9) y dispositivos AC10 con firmware hasta la versión V15.03.06.23_CN(AC10). Una vulnerabilidad de inyección de comandos permite que los atacantes ejecuten comandos arbitrarios del sistema operativo mediante una petición goform/setUsbUnload. Esto ocurre debido a que la función "formsetUsbUnload" ejecuta una función dosystemCmd con entradas no fiables.

Tenda AC7, AC9, and AC10 devices contain a command injection vulnerability due to the "formsetUsbUnload" function executes a dosystemCmd function with untrusted input. Successful exploitation allows an attacker to execute OS commands via a crafted goform/setUsbUnload request.
