• Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
• Place all controllers in locked cabinets and never leave them in the “Program” mode.
• Never connect programming software to any network other than the network intended for that device.
• Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
• Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
• Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
• When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

• COMPANY HEADQUARTERS LOCATION: Germany

3.4 RESEARCHER

National Motor Freight Traffic Association, Inc. (NMFTA) researchers Ben Gardiner and Anne Zachos reported this vulnerability to CISA.

4. MITIGATIONS

To most effectively mitigate general vulnerabilities of the powerline communication, any trucks, trailers, and tractors utilizing J2497 technology should disable all features where possible, except for backwards-compatibility with LAMP ON detection only. Users acquiring new trailer equipment should migrate all diagnostics to newer trailer bus technology. Users acquiring new tractor equipment should remove support for reception of any J2497 message other than LAMP messages.

ZF recommends:

• Moving away from security access and implementing the latest security feature authenticate (0x29)
• Ensure random numbers are generated from a cryptographically secure hardware true random number generator
• Adopting modern standards/protocols for truck trailer communication

NMFTA has published detailed information about how to mitigate these issues in the following ways:

• Install a LAMP ON firewall for each ECU
• Use a LAMP detect circuit LAMP ON sender with each trailer
• Change addresses dynamically on each tractor in response to detecting a transmitter on its current address.
• Install RF chokes on each trailer between chassis ground and wiring ground
• Load with LAMP keyhole signal on each tractor
• Flood with jamming signal on each tractor

Please visit NMFTA for additional details on these and other solutions.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• 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 current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

3.2 Vulnerability Overview

3.2.1 Reliance on Untrusted Inputs in a Security Decision CWE-807

By utilizing software-defined radios and a custom low-latency processing pipeline, RF signals with spoofed location data can be transmitted to aircraft targets. This can lead to the appearance of fake aircraft on displays and potentially trigger undesired Resolution Advisories (RAs).

CWE-2024-9310 has been assigned to this vulnerability. A CVSS v3.1 base score of 6.1 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:N).

A CVSS v4 score has also been calculated for CWE-2024-9310. A base score of 6.0 has been calculated; the CVSS vector string is (AV:A/AC:H/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N).

3.2.2 External Control of System or Configuration Setting CWE-15

For TCAS II systems using transponders compliant with MOPS earlier than RTCA DO-181F, an attacker can impersonate a ground station and issue a Comm-A Identity Request. This action can set the Sensitivity Level Control (SLC) to the lowest setting and disable the Resolution Advisory (RA), leading to a denial-of-service condition.

CVE-2024-11166 has been assigned to this vulnerability. A CVSS v3.1 base score of 8.2 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:H).

A CVSS v4 score has also been calculated for CVE-2024-11166. A base score of 7.1 has been calculated; the CVSS vector string is (AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N).
