CVE-2021-27440Network attack vector

Remote compromise via hard-coded password

Published Mar 25, 2021 · Updated Aug 3, 2024

Hard-coded credential flaw in General Electric Reason DR60 firmware before 02A04.1 allows remote attackers to compromise the device via network authentication. The firmware embeds a password for inbound authentication or outbound connections, but the specific authentication locus is undisclosed. Network access to the device is sufficient; successful use can expose data, alter settings, or interrupt recording.
