CVE-2021-22995
On all 7.x and 6.x versions (fixed in 8.0.0), BIG-IQ high availability (HA) when using a Quorum device for automatic failover does not implement any form of authentication with the Corosync daemon.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
