Check Point Zone Labs Multiple Products Privilege Escalation Vulnerability



Zone Alarm products provide security solutions such as anti-virus, firewall, spy-ware, and ad-ware protection. More information is available at the Zone Labs web site at the following URL.


Local exploitation of an insecure permission vulnerability in multiple Check Point Zone Labs products allows attackers to escalate privileges or disable protection.

The vulnerability specifically exists in the default file Access Control List (ACL) settings that are applied during installation. When an administrator installs any of the Zone Labs ZoneAlarm tools, the default ACL allows any user to modify the installed files. Some of the programs run as system services. This allows a user to simply replace an installed ZoneAlarm file with their own code that will later be executed with system-level privileges.


Exploitation allows local attackers to escalate privileges to the system level. It is also possible to use this vulnerability to simply disable protection by moving all of the executable files so that they cannot start on a reboot.


iDefense has confirmed the existence of this vulnerability in ZoneAlarm Security Suite and 6.5.737. It is strongly suspected that other versions of ZoneAlarm and other Zone Labs products are affected by this.


Apply proper Access Control List settings to the directory that ZoneAlarm Security Suite is installed in. The ACL rules should make sure that no regular users can modify files in the directory.


Check Point Zone Labs has addressed this vulnerability in version 7.0.362 of their ZoneAlarm products. For more information, consult the Check Point Zone Labs download page at the following URL.
