Published: 2008-11-05 15:59:22
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

We are not aware of a vendor approved solution at the current time. On the following platforms, we recommend you mitigate in the described manner: Checkpoint VPN-1 R55 Checkpoint VPN-1 R65 We recommend you mitigate in the following manner: Disable any implied rules and only open ports for required services Filter outbound ICMP time-to-live exceeded packets.

Checkpoint VPN-1 PAT information disclosure

Technical Details:
By sending crafted packets to ports on the firewall which are mapped by port address translation (PAT) to ports on internal devices, information about the internal network may be disclosed in the resulting ICMP error packets. Port 18264/tcp on the firewall is typically configured in such a manner, with packets to this port being rewritten to reach the firewall management server. For example, the firewall fails to correctly sanitise the encapsulated IP headers in ICMP time-to-live exceeded packets resulting in internal IP addresses being disclosed. False positive: This could be false positive alert. Try running same scan against single host where this vulnerability is reported.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
