Fortinet Fortigate Lack of certificate verification when establishing secure connections with threat feed fabric connectors (FG-IR-22-257)

high Nessus Plugin ID 174403

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-22-257 advisory.

- An improper certificate validation vulnerability [CWE-295] in FortiOS 7.2.0 through 7.2.3, 7.0.0 through 7.0.7, 6.4 all versions, 6.2 all versions, 6.0 all versions and FortiProxy 7.0.0 through 7.0.6, 2.0 all versions, 1.2 all versions may allow a remote and unauthenticated attacker to perform a Man-in-the-Middle attack on the communication channel between the FortiOS/FortiProxy device and remote servers hosting threat feeds (when the latter are configured as Fabric connectors in FortiOS/FortiProxy) (CVE-2022-39948)

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

Solution

Please upgrade to FortiProxy version 7.0.7/7.2.0 or later.
