Description

This module exploits an unauthenticated command injection vulnerability in rConfig versions 3.9.2 and prior. The `install` directory is not automatically removed after installation, allowing unauthenticated users to execute arbitrary commands via the `ajaxServerSettingsChk.php` file as the web server user. This module has been tested successfully on rConfig version 3.9.2 on CentOS 7.7.1908 (x64).

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
