Vulnerability Details CVE-2012-6439
                When an affected 
product receives a valid CIP message from an unauthorized or unintended 
source to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 
44818/UDP that changes the product’s configuration and network 
parameters, a DoS condition can occur. This situation could cause loss 
of availability and a disruption of communication with other connected 
devices.
