View CSAF Summary ATN-B1 CPDLC relies on legacy clear text unauthenticated radio frequency links. Research demonstrates that these characteristics allow unauthorized message injection, denial-of-service conditions, and forced session resets. These vulnerabilities do not constitute an unsafe aircraft condition but can degrade operational safety margins by increasing workload, delaying safety-critical instructions, and reducing situational awareness. The following versions of CPDLC over ATN-B1 Vulnerabilities are affected:
