Other ZoneAlarm products and versions are suspected to be vulnerable. - --------------------------BEGIN INCLUDED TEXT-------------------- Check Point Zone Labs Multiple Products Privilege Escalation Vulnerability iDefense Security Advisory 08.20.07 http://labs.idefense.com/intelligence/vulnerabilities/ Aug 20, 2007 I. BACKGROUND 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. http://www.zonelabs.com/ II. DESCRIPTION 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. III. ANALYSIS 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. IV. DETECTION iDefense has confirmed the existence of this vulnerability in ZoneAlarm Security Suite 5.5.062.004 and 6.5.737. It is strongly suspected that other versions of ZoneAlarm and other Zone Labs products are affected by this. V. 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. VI. VENDOR RESPONSE 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. http://www.zonealarm.com/store/content/catalog/products/trial_zaFamily/trial_zaFamily.jsp VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2005-2932 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
