			'Description'	=> %q{
					This module exploits the KarjaSoft Sami FTP Server version 2.02
				by sending an excessively long USER string. The stack is overwritten
				when the administrator attempts to view the FTP logs. Therefore, this exploit
				is passive and requires end-user interaction. Keep this in mind when selecting
				payloads. When the server is restarted, it will re-execute the exploit until
				the logfile is manually deleted via the file system.
