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-24-250 advisory.

(CVE-2024-46666)

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 7.4.5 or later. For 7.6.x, upgrade to Fortigate version 7.6.1 or later.
