Last modified

CVE-2025-1727 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. 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.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
