CVE-2024-41611Network attack vector

Unauthenticated command execution via hard-coded Telnet credentials

Published Jul 30, 2024 · Updated Aug 2, 2024

Hard-coded credentials in D-Link DIR-860L firmware 1.10B04 allow remote attackers to access Telnet and execute arbitrary commands. The Telnet service accepts a firmware-embedded credential pair instead of requiring device-specific authentication. Network reachability to Telnet is sufficient; a successful login grants a command interface on the router, exposing its data, configuration, and availability.
