critical Nessus Plugin ID 147627
New! Plugin Severity Now Using CVSS v3

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 11.6.5.3 / 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 K66851119 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, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, undisclosed endpoints in iControl REST allow for a reflected XSS attack, which could lead to a complete compromise of the BIG-IP system if the victim user is granted the admin role. This vulnerability is due to an incomplete fix for CVE-2020-5948. Note:
Software versions which have reached End of Software Development (EoSD) are not evaluated.
(CVE-2021-22994)

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

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K66851119.
