CVE-2026-125086 · Severity: critical · CVSS 10 · Published 2026-11-10

The D-Link M60 mesh router contains a built-in MQTT broker with fixed administrator credentials (admin/admin) that cannot be changed. An attacker on the local network or mesh backhaul can connect to the broker and inject mesh control commands, enabling unauthorized operations such as firmware updates, channel changes, and member device management with root privileges.

## Technical details

The emDaemon MQTT broker in D-Link M60 1.12.B01 is configured at boot with hard-coded credentials stored in the /usr/bin/commander binary and written to /etc/emDaemon/mosquitto.conf. The broker listens on 0.0.0.0:1883 without interface restrictions, allowing any adjacent network attacker to authenticate with the fixed admin/admin pair and subscribe to control topics. Connected attackers can trigger root-privileged command execution through topics monitored by EasyMeshDaemon and ACSDaemon, including member firmware downloads and system configuration changes.
