Vulnerability identifier: #VU17212

Vulnerability risk: Low

CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: N/A

CWE-ID: CWE-94

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
ZoneAlarm
Client/Desktop applications / Antivirus software/Personal firewalls

Vendor: Check Point Software Technologies

Description
The vulnerability allows a local low-privileged attacker to gain elevated privileges on the target system.

The weakness exists due to insecure implementation of inter-process communications within the ZoneAlarm application itself. A local attacker can hijack the insecure communications with a vulnerable .NET service that is running with SYSTEM-level privileges, inject and execute arbitrary code to bypass privilege restrictions and gain full control of the system.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation
Install update from vendor's website.
