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 14.1.4.1 / 16.1.0 / Hotfix- BIGIP-14.1.4.0.120.11-ENG.iso / Hotfix-BIGIP-16.0.1.1.9.6-ENG.iso. It is, therefore, affected by a vulnerability as referenced in the K37451543 advisory.
