"According to its self-reported version, the Cisco Finesse Software is affected by a denial of service vulnerability. 
The vulnerability occurs because a certain system log file does not have a maximum size restriction. This could allow an
unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS)
condition.
