The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.4.3 / 15.1.3.1 / 16.0.1.2 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K24301698 advisory.

  • On version 16.0.x before 16.0.1.2, 15.1.x before 15.1.3.1, and 14.1.x before 14.1.4.3, a DOM based cross- site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility that allows an attacker to execute JavaScript in the context of the currently logged-in user. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2021-23027)

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