Air Force Institute of Technology researcher Stephen Dunlap has identified vulnerabilities in Omron Corporation’s CX-Programmer software, CJ2M series programmable logic controller (PLC), and CJ2H series PLC. Omron Corporation has produced new versions that mitigate these vulnerabilities.
One of the three vulnerabilities could be exploited remotely.
The following Omron Corporation products are affected:
Successful exploitation of these vulnerabilities could result in the compromise of sensitive account information.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.
Omron Corporation is an international company headquartered in Kyoto, Japan.
The affected product, CX-Programmer, is part of the CX-One software suite, which is used to configure and program devices such as PLCs and HMIs. The CJ2M series device is a PLC primarily used for packaging and machine automation. The CJ2H series device is a PLC used for machine automation that requires image processing inspection of electrical components and high speed sorting on conveyors. According to Omron Corporation, these products are deployed across the Critical Manufacturing sector. Omron Corporation estimates that these products are used worldwide.
The password is transmitted in clear text to unlock the PLC for modification, which leaves the password vulnerable to packet sniffing.

ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should consider the following:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/).
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
