Description

On versions 15.0.0-15.1.0.1, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, and 12.1.0-12.1.5.1, BIG-IP systems setup for connection mirroring in a High Availability (HA) pair transfers sensitive cryptographic objects over an insecure communications channel. This is a control plane issue which is exposed only on the network used for connection mirroring.
