'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.
