CVSS v3 10.0
ATTENTION: Remotely exploitable/low skill level to exploit.
Vendor: Rockwell Automation
Equipment: Stratix 5900
Vulnerabilities: Improper Input Validation, Resource Management Errors,
Improper Authentication, Path Traversal.
REPOSTED INFORMATION
This advisory was originally posted to the NCCIC Portal on April 4, 2017, and
is being released to the NCCIC/ICS-CERT web site.
AFFECTED PRODUCTS
Rockwell Automation reports that these vulnerabilities affect the following
Stratix 5900 Services Routers:
Stratix 5900, All Versions prior to 15.6.3.
IMPACT
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.
MITIGATION
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:
http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?famID=15
(link is external)
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.
https://rockwellautomation.custhelp.com/app/answers/detail/a_id/942592 (link
is external)
Please also refer to Ciscos 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.
