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-21-239 advisory.

 - An improper certificate validation vulnerability [CWE-295] in FortiOS 6.0.0 through 6.0.14, 6.2.0 through 6.2.10, 6.4.0 through 6.4.8, 7.0.0 may allow a network adjacent and unauthenticated attacker to man-in- the-middle the communication between the FortiGate and some peers such as private SDNs and external cloud platforms. (CVE-2022-22306)

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 6.4.9/7.0.1 or later.
