Fortinet FortiClient 6.2.x < 6.2.1 Missing Encryption Of Sensitive Data Vulnerability (macOS)

high Nessus Plugin ID 125404

Language:

Synopsis

The remote MacOS is affected by a denial of service vulnerability.

Description

The version of Fortinet FortiClient Mac running on the remote host is prior to 6.2.1. It is, therefore, affected by a missing encryption of sensitive data vulnerability. An attacker can access VPN session cookie from an endpoint device running FortiClient. The attacker can steal the cookies only if endpoint device has been compromised in such a way that the attacker has access to FortiClient's debug logs or memory space. Furthermore, practical use of the stolen cookie requires the attacker to spoof the endpoint's IP address.

Solution

Upgrade to Fortinet FortiClient 6.2.1 or later.
