  - On BIG-IP AFM version 16.x before 16.1.0, 15.1.x before 15.1.5, 14.1.x before 14.1.4.5, and all versions
    of 13.1.x, when global AFM SYN cookie protection (TCP Half Open flood vector) is activated in the AFM
    Device Dos or DOS profile, certain types of TCP connections will fail. Note: Software versions which have
    reached End of Technical Support (EoTS) are not evaluated. (CVE-2022-23028)

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