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 multiple vulnerabilities as referenced in the FG-IR-23-015 advisory.

- A null pointer dereference in Fortinet FortiOS before 7.2.5, before 7.0.11 and before 6.4.13, FortiProxy before 7.2.4 and before 7.0.10 allows attacker to denial of sslvpn service via specifically crafted request in bookmark parameter. (CVE-2023-33306)

- A null pointer dereference in Fortinet FortiOS before 7.2.5 and before 7.0.11, FortiProxy before 7.2.3 and before 7.0.9 allows attacker to denial of sslvpn service via specifically crafted request in network parameter. (CVE-2023-33307)

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

Solution

Please upgrade to FortiOS version 6.4.13/7.0.11/7.2.5/7.4.0 or later.
