"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.");
