medium Nessus Plugin ID 205428

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-24-012 advisory.

- An improper access control vulnerability [CWE-284] in FortiOS 7.4.0 through 7.4.3, 7.2.5 through 7.2.7, 7.0.12 through 7.0.14 and 6.4.x may allow an attacker who has already successfully obtained write access to the underlying system (via another hypothetical exploit) to bypass the file integrity checking system.
(CVE-2024-36505)

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

Solution

Upgrade to Fortigate version 6.4.999999 / 7.0.15 / 7.2.8 / 7.4.4 or later.
