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-24-058 advisory.

 - A channel accessible by non-endpoint vulnerability [CWE-300] in Fortinet FortiOS version 7.4.0 through 7.4.3, 7.2.0 through 7.2.7 and before 7.0.14 & FortiProxy version 7.4.0 through 7.4.3, 7.2.0 through 7.2.9 and before 7.0.16 allows an unauthenticated attacker with the knowledge of device specific data to spoof the identity of a downstream device of the security fabric via crafted TCP requests. (CVE-2024-50568)

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

Solution

For 6.4.x / 7.0.x, see vendor advisory. For 7.2.x, upgrade to Fortigate version 7.2.9 or later. For 7.4.x, upgrade to Fortigate version 7.4.4 or later.
