Vulnerable Systems:
* ZoneAlarm Security Suite version 5.5.062.004 and 6.5.737.
* It is strongly suspected that other versions of ZoneAlarm and other Zone Labs products are affected
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.
Workaround:
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.
Vendor status:
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.
