CVE-2020-5886
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.81%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
