17.1.0. It is, therefore, affected by a vulnerability as referenced in the K83284425 advisory.

  - In BIG-IP versions 17.0.x before 17.0.0.2, 16.1.x before 16.1.3.3, 15.1.x before 15.1.8.1, 14.1.x before
    14.1.5.3, and all versions of 13.1.x, and all versions of BIG-IQ 8.x and 7.1.x, incorrect permission
    assignment vulnerabilities exist in the iControl REST and TMOS shell (tmsh) dig command which may allow an
    authenticated attacker with resource administrator or administrator role privileges to view sensitive
    information. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
    (CVE-2023-22326)

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