CVE-2019-19223Public exploitNetwork attack vector

Unauthenticated reboot via unprotected administration endpoint

Published Mar 4, 2020 · Updated Aug 5, 2024

Broken access control in D-Link DSL-2680 firmware EU_1.03 allows remote attackers to reboot the router through its web interface. The web administration interface accepts a GET request to reboot.html without first enforcing an authenticated administrator session. Network access to that interface is sufficient, and successful requests interrupt service by rebooting the device.
