F5 Networks BIG-IP : BIG-IP DNS vulnerability (K45407662)

high Nessus Plugin ID 184270

Language:

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 13.1.5 / 14.1.4.4 / 15.1.3.1 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K45407662 advisory.

 - On version 16.x before 16.1.0, 15.1.x before 15.1.3.1, 14.1.x before 14.1.4.4, and all versions of 13.1.x and 12.1.x, when a BIG-IP DNS system is configured with non-default Wide IP and pool settings, undisclosed DNS responses can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2021-23032)

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 K45407662.
