CVE-2020-13150Public exploit

Configuration access via delayed MAC filter activation

Published Jun 15, 2020 · Updated Aug 4, 2024

Access control bypass in D-Link DSL-2750U ME1.03 and earlier allows attackers on the local Wi-Fi network to change settings after a reboot. During startup, MAC address filtering rules become active only after an approximately 90-second delay, leaving the control panel reachable. Exploitation requires local Wi-Fi reachability and a physical reboot, and the exposed panel permits device-configuration changes during that window.
