F5 Networks BIG-IP : BIG-IP high availability state mirroring vulnerability (K72540690)

critical Nessus Plugin ID 138234

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 16.0.0. It is, therefore, affected by a vulnerability as referenced in the K72540690 advisory.

 - On versions 15.0.0-15.1.0.3, 14.1.0-14.1.2.4, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, the default deployment mode for BIG-IP high availability (HA) pair mirroring is insecure. This is a control plane issue that is exposed only on the network used for mirroring. (CVE-2020-5884)

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 K72540690.
