17.0.0. It is, therefore, affected by a vulnerability as referenced in the K53197140 advisory.

  - On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior
    to 14.1.4.6, 13.1.x versions prior to 13.1.5, and all versions of 12.1.x and 11.6.x, directory traversal
    vulnerabilities exist in undisclosed iControl REST endpoints and TMOS Shell (tmsh) commands in F5 BIG-IP
    Guided Configuration, which may allow an authenticated attacker with at least resource administrator role
    privileges to read arbitrary files. Note: Software versions which have reached End of Technical Support
    (EoTS) are not evaluated (CVE-2022-26835)

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