Risk evaluation
Successful exploitation of these vulnerabilities could allow an attacker to trick a user in to opening a malicious JT file with any of the affected products, which could cause the application to crash or lead to arbitrary code execution.
Critical infrastructure sectors
Multiple Sectors
Countries/areas deployed
Worldwide
Company headquarters location
Germany
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best 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 webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
Recommended Practices
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
