Head-of-Train (also known as a FRED) relies on a BCH checksum for packet
creation. It is possible to create these EoT and HoT packets with a
software defined radio and issue brake control commands to the EoT
device, disrupting operations or potentially overwhelming the brake
systems.

EUVD-2025-21087 | The protocol used for remote linking over RF for End-of-Train and Head-of-Train (also known as a FRED) relies on a BCH checksum for packet creation. It is possible to create these EoT and HoT packets with a software defined radio and issue brake control commands to the EoT device, disrupting operations or potentially overwhelming the brake systems. |
Solution
No solution given by the vendor.
Workaround
The Association of American Railroads (AAR) is pursuing new equipment and protocols which should replace traditional End-of-Train and Head-of-Train devices. The standards committees involved in these updates are aware of the vulnerability and are investigating mitigating solutions. The AAR Railroad Electronics Standards Committee (RESC) maintains this protocol which is used by multiple manufacturers across the industry, including Hitachi Rail STS USA, Wabtec, Siemens, and others. Users of EoT/HoT devices are recommended to contact their own device manufacturers with questions.
