ICS‑CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation. Impact to individual organizations depends on many factors that are unique to each organization. The master station must be manually restarted to recover from the loop condition. A successful attack exploiting this vulnerability could allow an attacker to put the master station into an infinite loop, causing a denial-of-service condition.
WHAT FIREWALL RULES COULD BLOCK CONNECTION WITH KEPWARE SERIAL
The master station can be sent into an infinite loop by sending a specially crafted TCP packet or through serial communications.
WHAT FIREWALL RULES COULD BLOCK CONNECTION WITH KEPWARE DRIVER
Kepware Technologies’ DNP Master Driver for the KEPServerEX Communicaitons Platform (Version v5.11.250.0).The following Kepware Technologies products are affected: This vulnerability could be exploited remotely. The researchers have tested the new version to validate that it resolves the vulnerability. Kepware Technologies has produced a new version that mitigates this vulnerability. It it not neccessary to configure Open settings if you use an automatic open UDP/IP port(5000).Adam Crain of Automatak and independent researcher Chris Sistrunk have identified a improper input validation vulnerability in the Kepware Technologies’ DNP Master Driver for the KEPServerEX Communications Platform.Please select "Confirm" at Existence confirmation.Please input Port No by hex digit format.Please select "Procedure exist" at Fixed buffer communication procedure.It is necessary to configure the "Initial setting" as right. You push the "Open settings" of Network parameter screen.

At this time, it is not possible to be reconnected be not of Ethernet (The port is in the state of the unclose) it of the unit in the state of LISN, and set the living confirmation parameter appropriately, please. OPC Server can't communicate though it retries to communicate for the set times, and OPC Server tries to reconnect after it closes the connection. If the communication trouble occurs by the cable determination or the influence of the collision, etc, OPC Server becomes time-out error when it can't receive the response from PLC in the set time.*The default value "10 minutes" means that it is impossible to communicate for 10 minutes after communication has been stopped. *The existence confirmation processing will be performed 3 times at 10 seconds intervals after communication has been stopped for 5 seconds.

It is necessary to configure the "Initial setting" as follow. You push the "Initial setting" button of Network parameter screen.
WHAT FIREWALL RULES COULD BLOCK CONNECTION WITH KEPWARE SERIAL NUMBERS
Ethernet units that have serial numbers with 05051 or later as the upper five digits and function version B or later can use this function.For other models, use Ping.
