False Emergency Message Injection in CPDLC Systems

Executive Summary

This vulnerability involves injecting false emergency or status messages into the Controller-Pilot Data Link Communications (CPDLC) system. Attackers can remotely transmit misleading information over radio frequency, causing confusion among flight crews, air traffic controllers, and ground operations. This may lead to misallocation of resources and improper response actions.
