The U.S. Department of Homeland Security has warned of critical security vulnerabilities in Emergency Alert System encoder/decoder devices.

The issues could allow an adversary to issue fraudulent emergency alerts over TV, radio, and cable networks.

CYBIR security researcher Ken Pyle has been credited with discovering the shortcoming.

EAS is a U.S. national public warning system that enables state authorities to disseminate information within 10 minutes during an emergency.

Such alerts can interrupt radio and television to broadcast emergency alert information.

"In short, the vulnerability is public knowledge and will be demonstrated to a large audience in the coming weeks," the agency said in the bulletin.
