OVERVIEW

Alexander Bolshev and Svetlana Cherkasova of Digital Security have identified an improper input vulnerability in the CodeWrights GmbH HART Device Type Manager (DTM) library used in Endress+Hauser HART Device DTM. CodeWrights GmbH has addressed the vulnerability with a new library, which Endress+Hauser has begun to integrate.

IMPACT

The vulnerability could cause a buffer overflow in the HART Device DTM, crashing the Field Device Tool (FDT) Frame Application. The Frame Application must then be restarted to restore functionality. The Frame Application is used primarily for remote configuration. Exploitation of this vulnerability does not result in loss of information, control, or view by the control system of the HART devices on the 4-20 mA HART Loop.

Impact to individual organizations depends on many factors that are unique to each organization and systems implementation. NCCIC/ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.

BACKGROUND

Endress+Hauser is an International-based company based in Germany and Switzerland, with over 200 offices and production centers located worldwide.

The affected product is the DTM library used by Endress+Hauser HART-based field devices in the FDT/DTM Frame Application. According to Endress+Hauser, these products are deployed across multiple critical infrastructure sectors worldwide.

VULNERABILITY CHARACTERISTICS

VULNERABILITY OVERVIEW

IMPROPER INPUT VALIDATIONa

Successful injection of specially crafted packets to the Device DTM causes a buffer overflow condition in the Frame Application. The FDT Frame Application becomes unresponsive, and the Device DTM stops functioning.

CVE-2014-9191b has been assigned to this vulnerability. A CVSS v2 base score of 1.8 has been assigned; the CVSS vector string is (AV:A/AC:H/Au:N/C:N/I:N/A:P).c

VULNERABILITY DETAILS

EXPLOITABILITY

This exploit on the FDT/DTM Frame Application is possible from any adjacent network that receives or passes packets from the HART Device DTM.

EXISTENCE OF EXPLOIT

No known public exploits specifically target this vulnerability.

DIFFICULTY

This is a complex vulnerability. Crafting a working exploit for this vulnerability would be difficult. Compromised access that allows access to the packets transmitted to Frame Application is required for exploitation. This exploit also requires a specific timing to crash the Frame Application. This increases the difficulty of a successful exploit.

MITIGATION

Endress+Hauser has released a security update addressing the HART Device DTMs. The update can be downloaded here:

Endress+Hauser Inc. - Technical support
Tel.: 888-ENDRESS
techsupport@us.endress.com

Endress+Hauser has recommended owners/operators to update HART DTM library 2.41 and FDT tool FieldCare to Version 2.10. For further information please consult the Release Notes and the Technical Information.

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 also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

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 (http://ics-cert.us-cert.gov/).

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.
