Vendor: Rockwell Automation
Equipment: Stratix 5900
Vulnerabilities: Improper Input Validation, Resource Management Errors, Improper Authentication, Path Traversal.
This advisory was originally posted to the NCCIC Portal on April 4, 2017, and is being released to the NCCIC/ICS-CERT web site.
Rockwell Automation reports that these vulnerabilities affect the following Stratix 5900 Services Routers:
- Stratix 5900, All Versions prior to 15.6.3.
An attacker who exploits these vulnerabilities may be able to perform man-in-the-middle attacks, create denial of service conditions, or remotely execute arbitrary code.
Rockwell Automation has provided a new firmware version, Version 15.6.3, to mitigate these vulnerabilities.
Rockwell Automation encourages users of the affected versions to update to the latest available software versions addressing the associated risk, and including improvements to further harden the software and enhance its resilience against similar malicious attacks. Users can find the latest firmware version by searching for their device at the following web site:
Additional precautions and risk mitigation strategies specific to these types of attacks are recommended in the Rockwell Automation security release. When possible, multiple strategies should be implemented simultaneously.
Please also refer to Cisco’s security advisories (linked below) for additional workarounds and details for these vulnerabilities.
NCCIC/ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
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. 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.
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.
No known public exploits specifically target these vulnerabilities.
