CVE reference:CVE-2007-0471


Description:
Roni Bachar and Nir Goldshlager have reported a vulnerability in Check Point products, which can be exploited by malicious people to bypass certain security restrictions.

The problem is that /sre/params.php in ICS (Integrity Clientless Security) does not properly validate the data being sent to it. This can be exploited to receive a cookie, which can be used to bypass certain checks before being allowed to log in to the network, by sending a POST request with a valid report to the /sre/params.php page.

Successful exploitation requires that the ICS feature is enabled.

The vulnerability affects the following products and versions:
* Connectra NGX R62
* Connectra NGX R61
* Connectra NGX R60
* Connectra 2.0
* VPN-1 Power/UTM (Pro/Express) NGX R62
* VPN-1 Power/UTM (Pro/Express) NGX R61
* VPN-1 Power/UTM (Pro/Express) NGX R60
* VPN-1 Power/UTM (Pro/Express) NG AI R55W
* VPN-1 Power/UTM (Pro/Express) NG AI R55

Solution:
Apply hotfix.
