    to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x, when running in Appliance mode,
    an authenticated user assigned the Administrator role may be able to bypass Appliance mode restrictions,
    utilizing an undisclosed iControl REST endpoint. Note: Software versions which have reached End of
    Technical Support (EoTS) are not evaluated (CVE-2022-26415)

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