Risk evaluation
Successful exploitation of this vulnerability could result in a denial-of-service condition. As a result, the controller goes into a Major Non-Recoverable Fault (MNRF) state, which is considered safe. However, recovery requires the user to download the application program again.
Critical infrastructure sectors
Chemical, Critical Manufacturing, Food and Agriculture, Transportation Systems, Water and Wastewater Systems
Countries/areas deployed
Worldwide
Company headquarters location
Milwaukee, Wisconsin
Recommended Practices
NCCIC recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
Recommended Practices
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.NCCIC also provides a section for control systems security recommended practices on the ICS-CERT web page. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
Exploitability
No known public exploits specifically target this vulnerability.
