high Nessus Plugin ID 133358
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote host is running a version of FortiOS prior to 6.2.3.
It is, therefore, affected by an information disclosure vulnerability due to a cleartext storage in a file or on disk. FortiOS SSL VPN allows an attacker to retrieve a logged-in SSL VPN user's credentials should that attacker be able to read the session file stored on the targeted device's system.

Solution

Upgrade to Fortinet FortiOS version to 6.2.3 or later.
