Check Point ZoneAlarm Extreme Security Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Check Point ZoneAlarm Extreme Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Forensic Recorder service. By creating a symbolic link, an attacker can abuse the service to overwrite arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-21677.

A local attacker can escalate privileges on affected Check Point ZoneAlarm Extreme Security NextGen, Identity Agent for Windows, and Identity Agent for Windows Terminal Server. To exploit this vulnerability, an attacker must first obtain the ability to execute local privileged code on the target system.

Check Point ZoneAlarm Extreme Security before 15.8.211.19229 allows local users to escalate privileges. This occurs because of weak permissions for the %PROGRAMDATA%\CheckPoint\ZoneAlarm\Data\Updates directory, and a self-protection driver bypass that allows creation of a junction directory. This can be leveraged to perform an arbitrary file move as NT AUTHORITY\SYSTEM.

Check Point ZoneAlarm before version 15.8.200.19118 allows a local actor to escalate privileges during the upgrade process. In addition, weak permissions in the ProgramData\CheckPoint\ZoneAlarm\Data\Updates directory allow a local attacker the ability to execute an arbitrary file write, leading to execution of code as local system, in ZoneAlarm versions before v15.8.211.192119

Check Point ZoneAlarm before version 15.8.139.18543 allows a local actor to escalate privileges while restoring files in Anti-Ransomware.

Check Point ZoneAlarm before version 15.8.139.18543 allows a local actor to delete arbitrary files while restoring files in Anti-Ransomware.

ZoneAlarm Anti-Ransomware before version 1.0.713 copies files for the report from a directory with low privileges. A sophisticated timed attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links. This allows an unprivileged user to enable escalation of privilege via local access.

ZoneAlarm Firewall and Antivirus products before version 15.8.109.18436 allow an attacker who already has access to the system to execute code at elevated privileges through a combination of file permission manipulation and exploitation of Windows CVE-2020-00896 on unpatched systems.

A hard-link created from log file archive of Check Point ZoneAlarm up to 15.4.062 or Check Point Endpoint Security client for Windows before E80.96 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.

A hard-link created from the log file of Check Point ZoneAlarm up to 15.4.062 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.
