Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The expiretable configuration in pfSense 2.4.4_1 establishes block durations that are incompatible with the block durations implemented by sshguard, which might make it easier for attackers to bypass intended access restrictions.
