What is CVE-2018-20799?

In pfSense version 2.4.4_1, there is an inconsistency in the management of blocking source IP addresses based on failed HTTPS authentication compared to failed SSH authentication. This discrepancy does not align with the behavior outlined in the sshguard documentation, potentially allowing attackers to exploit this inconsistency and bypass the intended access restrictions set within the system.
