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-22-223 advisory.

 - An exposure of sensitive information to an unauthorized actor vulnerabiltiy [CWE-200] in FortiOS SSL-VPN versions 7.2.0, versions 7.0.0 through 7.0.6 and versions 6.4.0 through 6.4.9 may allow a remote unauthenticated attacker to gain information about LDAP and SAML settings configured in FortiOS.
 (CVE-2022-35842)

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