The version of F5 Networks BIG-IP installed on the remote host is prior to 12.1.5.3 / 13.1.3.6 / 14.1.4 / 15.1.2.1 / 16.0.1.1 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K03009991 advisory.

  • On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, and 12.1.x before 12.1.5.3 amd BIG-IQ 7.1.0.x before 7.1.0.3 and 7.0.0.x before 7.0.0.2, the iControl REST interface has an unauthenticated remote command execution vulnerability. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. (CVE-2021-22986)

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