Descriptions

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.

Los productos ZoneAlarm Firewall y Antivirus anteriores a versión 15.8.109.18436, permiten a un atacante que ya posee acceso al sistema ejecutar código con privilegios elevados por medio de una combinación de manipulación de permisos de archivos y explotación de Windows CVE-2020-00896 en sistemas sin parches

This vulnerability allows local attackers to escalate privileges on affected installations of Check Point ZoneAlarm. 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 ZoneAlarm Service. The issue results from the lack of proper validation of a user-supplied symbolic link prior to using it in file operations. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of SYSTEM.
