Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-20-009 advisory.

 - A cleartext storage of sensitive information vulnerability in FortiOS command line interface in versions 6.2.4 and earlier and FortiProxy 2.0.0, 1.2.9 and earlier may allow an authenticated attacker to obtain sensitive information such as users passwords by connecting to FortiGate CLI and executing the diag sys ha checksum show command. (CVE-2020-6648)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Please upgrade to FortiOS version 6.0.12/6.2.5/6.4.0 or later.
