therefore, affected by a vulnerability as referenced in the K68647001 advisory.

  - On all versions of 16.1.x, 15.1.x, 14.1.x, 13.1.x, 12.1.x, and 11.6.x of F5 BIG-IP Advanced WAF, ASM, and
    ASM, and F5 BIG-IP Guided Configuration (GC) all versions prior to 9.0, when running in Appliance mode, an
    authenticated attacker assigned the Administrator role may be able to bypass Appliance mode restrictions,
    utilizing command injection vulnerabilities in undisclosed URIs in F5 BIG-IP Guided Configuration. Note:
    Software versions which have reached End of Technical Support (EoTS) are not evaluated (CVE-2022-27806)

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