Descriptions

In the /HNAP1/SetClientInfoDemo message, the AudioMute and AudioEnable parameters are vulnerable, and the vulnerabilities affect D-Link DIR-868L Rev.B 2.05B02 devices. In the SetClientInfoDemo.php source code, the AudioMute and AudioEnble parameters are saved in the ShellPath script file without any regex checking. After the script file is executed, the command injection occurs. It needs to bypass the wget command option with a single quote. A vulnerable /HNAP1/SetClientInfoDemo XML message could have single quotes and backquotes in the AudioMute or AudioEnable element, such as the '`telnetd`' string.

En el mensaje HNAP1/SetClientInfoDemo, los parámetros AudioMute y AudioEnable son vulnerables y las vulnerabilidades afectan a los dispositivos D-Link DIR-868L Rev.B 2.05B02. En el código fuente del archivo SetClientInfoDemo.php, los parámetros AudioMute y AudioEnble se guardan en el archivo de script shellPath sin ninguna comprobación regex. Despueés que se ejecuta el archivo de script, se produce la inyección de comandos. Debe omitir la opción del comando wget con una sola cita. Un mensaje XML vulnerable /HNAP1/SetClientInfoDemo podría tener comillas simples e invertidas en el elemento AudioMute o AudioEnable, como la cadena '`telnetd`'.
