"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-20-014 advisory.

  - A clear text storage of sensitive information (CWE-312) vulnerability in both FortiGate version 6.4.0
    through 6.4.1, 6.2.0 through 6.2.9 and 6.0.0 through 6.0.13 and FortiAuthenticator version 5.5.0 and all
    versions of 6.1 and 6.0 may allow a local unauthorized party to retrieve the Fortinet private keys used to
    establish secure communication with both Apple Push Notification and Google Cloud Messaging services, via
    accessing the files on the filesystem. (CVE-2022-22302)

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