The Zero-Day-Initiative (ZDI) draws attention to the vulnerability CVE-2020-6013. This vulnerability was discovered on May 20, 2020 and allows local attackers to extend privileges on affected Check Point ZoneAlarm installations. To exploit this vulnerability, an attacker must first gain the ability to execute low privileged code on the target system.
The specific vulnerability exists within the ZoneAlarm service. The issue arises from the lack of proper validation of a user-supplied symbolic link before it is used in file operations. An attacker could exploit this vulnerability to escalate privileges and execute code in the SYSTEM context.
