Summary
ICSA-21-040-06_Siemens JT2Go and Teamcenter Visualization (Update A)

Notes

Summary
Siemens has released version V13.1.0.2 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in ASM and PAR file formats. If a user is tricked to opening of a malicious file with the affected products, this could lead to application crash, or potentially arbitrary code execution or data extraction on the target host system. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Recommended Practices
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Recommended Practices
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
Recommended Practices
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
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 on cisa.gov. 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
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov 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.
