TITLE

ZoneAlarm Product Multiple Local Licensing Boosts

DESCRIPTION

Multiple Check Point Zone Labs ZoneAlarm products before 7.0.362, including ZoneAlarm Security Suite 5.5.062.004 and 6.5.737, use insecure default permissions for critical files, which allows local users to gain privileges or bypass security controls. Multiple Check Point ZoneAlarm products are prone to local privilege-escalation vulnerabilities. An attacker can exploit these issues to gain elevated privileges and completely compromise an affected computer. These issues have been confirmed in: ZoneAlarm 6.5.737 ZoneAlarm Security Suite 5.5.062.004 and 6.5.737. Other versions are likely vulnerable as well. The following are vulnerable: - Versions prior to ZoneAlarm 7.0.362 - Zone Labs products that include 'vsdatant.sys' 6.5.737.0. ZoneAlarm is a personal computer firewall that protects personal data and privacy. The IOCTL handling code of the ZoneAlarm product vsdatant.sys device driver does not validate the userland-supplied addresses passed to IOCTL 0x8400000F and IOCTL 0x84000013. ---------------------------------------------------------------------- BETA test the new Secunia Personal Software Inspector!

SOLUTION: Update to version 7.0.362. http://www.zonealarm.com/store/content/catalog/download_buy.jsp?dc=12bms&ctry=US&lang=en PROVIDED AND/OR DISCOVERED BY: 1) Ruben Santamarta, reported via iDefense Labs. 2) Discovered by an anonymous person and reported via iDefense Labs.

BACKGROUND Zone Alarm products provide security solutions such as anti-virus, firewall, spy-ware, and ad-ware protection. http://www.zonelabs.com/ II. 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. 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. 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.
