Vigil@nce - Check Point R75.40VS: information disclosure via SecureXL

August 2013 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

An attacker can capture SIP/MGCP packets when SecureXL is enabled
on Check Point R75.40VS, in order to obtain sensitive information.

Impacted products: CheckPoint IP Appliance, CheckPoint Power-1
Appliance, CheckPoint Security Gateway, CheckPoint UTM-1
Appliance, CheckPoint VSX-1

Severity: 2/4

Creation date: 02/08/2013

DESCRIPTION OF THE VULNERABILITY

The SecureXL technology improves the performance of Check Point
firewalls.

However, when it is enabled on R75.40VS, then SIP (Session
Initiation Protocol) and MGCP (Media Gateway Control Protocol)
packets are not encrypted.

An attacker can therefore capture SIP/MGCP packets when SecureXL
is enabled on Check Point R75.40VS, in order to obtain sensitive
information.
