CVE-2021-23005
On all 7.x and 6.x versions (fixed in 8.0.0), when using a Quorum device for BIG-IQ high availability (HA) for automatic failover, BIG-IQ does not make use of Transport Layer Security (TLS) with the Corosync protocol.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
