ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.Īdditional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B-Targeted Cyber Intrusion Mitigation Strategies, that is available for download from the ICS-CERT web site ( ). Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at.
When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPN is only as secure as the connected devices. Locate control system networks and remote devices behind firewalls, and isolate them from the business network. Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet. Kepware Technical email is: encourages asset owners to take additional defensive measures to protect against this and other cybersecurity risks.

Information about the new version is available at the Kepware support site to registered users at (login required): Kepware Technologies has produced a new version of the software, V5.17.495.0, which resolves the vulnerability. Remote devices should not return a variation of 0 to a master, and a master that encounters a zero length message from a remote should stop processing that message.ĭNP3 Application Note AN2013-004b Validation of Incoming DNP3 Data, published August 13, 2014, addresses this issue. DIFFICULTYĪn attacker with a moderate skill would be able to exploit this vulnerability. No known public exploits specifically target this vulnerability. This vulnerability could be exploited remotely. A CVSS v2 base score of 7.5 has been assigned the CVSS vector string is (AV:N/AC:L/Au:N/C:P/I:P/A:P). This is not a universal problem for all DNP3 users, vendors, or integrators, but it may occur. UNCONTROLLED RESOURCE CONSUMPTION (RESOURCE EXHAUSTION) aĪ vague interpretation of the DNP3 protocol may allow a specially crafted response to create large numbers of entries in the master in some implementations. VULNERABILITY CHARACTERIZATION VULNERABILITY OVERVIEW #Kepware software#
The affected product is a Microsoft Windows-based software that facilitates connectivity to multiple DNP3 compliant devices such as HMI, RTU, PLC and meters.Īccording to Kepware Technologies, the KEPServerEX is deployed worldwide in over 100 countries, across several sectors including Chemical, Commercial Facilities, Critical Manufacturing, Energy, Food and Agriculture, Information Technology, and Water and Wastewater Systems. The KEPServerEX Communications Platform is used for industry and third-party connectivity communication software for automation, both OPC and embedded device communications. Kepware Technologies is a US-based company that maintains offices primarily in Portland, Maine. NCCIC/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.
