Synopsis

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

Description

The version of Fortigate FortiOS installed on the remote host is 6.2.x < 6.2.14, 6.4.x < 6.4.12, 7.0.x < 7.0.10, or 7.2.x < 7.2.4. It is, therefore, affected by a vulnerability as referenced in the FG-IR-22-477 advisory:

- An access of uninitialized pointer vulnerability [CWE-824] in the SSL-VPN portal of FortiOS & FortiProxy may allow a remote authenticated attacker to crash the sslvpn daemon via an HTTP GET request.
(CVE-2022-45861)

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 FortiOS version 6.2.14 / 6.4.12 / 7.0.10 / 7.2.4 or later.
