vulnerability as referenced in the FG-IR-22-229 advisory.

    7.0.6 and 6.4.0 through 6.4.8 and FortiConverter (Windows) versions 6.2.0 through 6.2.1, 7.0.0 and all
    versions of 6.0.0 may allow a local authenticated attacker to tamper with files in the installation
    folder, if FortiClient or FortiConverter is installed in an insecure folder. (CVE-2022-33877)

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