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.

Some of the DLLs loaded by Check Point ZoneAlarm up to 15.4.062 are taken from directories where all users have write permissions. This can allow a local attacker to replace a DLL file with a malicious one and cause Denial of Service to the client.

A local attacker can create a hard-link between a file to which the Check Point Endpoint Security client for Windows before E80.96 writes and another BAT file, then by impersonating the WPAD server, the attacker can write BAT commands into that file that will later be run by the user or the system.

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.

Check Point Endpoint Security Client for Windows, with the VPN blade, before version E80.83, starts a process without using quotes in the path. This can cause loading of a previously placed executable with a name similar to the parts of the path, instead of the intended one.

Check Point Endpoint Security Initial Client for Windows before version E81.30 tries to load a DLL placed in any PATH location on a clean image without Endpoint Client installed. An attacker can leverage this to gain LPE using a specially crafted DLL placed in any PATH location accessible with write permissions to the user.

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.

Check Point Endpoint Security Client for Windows before version E84.20 allows write access to the directory from which the installation repair takes place. Since the MS Installer allows regular users to run the repair, an attacker can initiate the installation repair and place a specially crafted DLL in the repair folder which will run with the Endpoint client’s privileges.

Mobile Access Portal Native Applications who's path is defined by the administrator with environment variables may run applications from other locations by the Mobile Access Portal Agent.

The Harmony Browse and the SandBlast Agent for Browsers installers must have admin privileges to execute some steps during the installation. Because the MS Installer allows regular users to repair their installation, an attacker running an installer before 90.08.7405 can start the installation repair and place a specially crafted binary in the repair folder, which runs with the admin privileges.

Users have access to the directory where the installation repair occurs. Since the MS Installer allows regular users to run the repair, an attacker can initiate the installation repair and place a specially crafted EXE in the repair folder which runs with the Check Point Remote Access Client privileges.

The Check Point Gaia Portal's GUI Clients allowed authenticated administrators with permission for the GUI Clients settings to inject a command that would run on the Gaia OS.
