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).

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/unix/webapp/rconfig_install_cmd_exec
msf exploit(rconfig_install_cmd_exec) > show targets
    ...targets...
msf exploit(rconfig_install_cmd_exec) > set TARGET < target-id >
msf exploit(rconfig_install_cmd_exec) > show options
    ...show and set options...
msf exploit(rconfig_install_cmd_exec) > exploit

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.
