  - In BIG-IP Versions 17.0.x before 17.0.0.1, 16.1.x before 16.1.3.1, 15.1.x before 15.1.6.1, 14.1.x before
    14.1.5.1, and all versions of 13.1.x, certain iRules commands may allow an attacker to bypass the access
    control restrictions for a self IP address, regardless of the port lockdown settings. Note: Software
    versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2022-33962)

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