The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.5 / 15.1.5.1 / 16.1.3 / 17.0.0. It is, therefore, affected by a vulnerability as referenced in the K11010341 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- In BIG-IP Versions 16.1.x before 16.1.3, 15.1.x before 15.1.5.1, 14.1.x before 14.1.5, and all versions of
13.1.x, when running in Appliance mode, an authenticated user assigned the Administrator role may be able
to bypass Appliance mode restrictions, using an undisclosed iControl REST endpoint. A successful exploit
can allow the attacker to cross a security boundary. Note: Software versions which have reached End of
Technical Support (EoTS) are not evaluated. (CVE-2022-35243)
