Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 12.1.5.2 / 13.1.3.4 / 14.1.2.7 / 15.1.0.5 / 16.0.0. It is, therefore, affected by a vulnerability as referenced in the K20606443 advisory.

 - In BIG-IP versions 15.0.0-15.1.0.4, 14.1.0-14.1.2.6, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.2, iControl REST does not implement Cross Site Request Forgery protections for users which make use of Basic Authentication in a web browser. (CVE-2020-5922)

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