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.
