      'Description'    => %q{
        This module exploits a vulnerability found in ZPanel's htpasswd module. When
        creating .htaccess using the htpasswd module, the username field can be used to
        inject system commands, which is passed on to a system() function for executing
        the system's htpasswd's command.
 
        Please note: In order to use this module, you must have a valid account to login
        to ZPanel.  An account part of any of the default groups should suffice, such as:
        Administrators, Resellers, or Users (Clients).  By default, there's already a
        'zadmin' user, but the password is randomly generated.
