IMPROPER INPUT VALIDATIONSuccessful 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-2014-9191 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). VULNERABILITY DETAILS EXPLOITABILITYThis 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 EXPLOITNo known public exploits specifically target this vulnerability. DIFFICULTYThis 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. MITIGATIONEndress+Hauser has released a security update addressing the HART Device DTMs. The update can be downloaded here:Endress+Hauser Inc. Technical supportTel.: 888-ENDRESSEndress+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:.
