# D-Link E15, M32, R15, R32 routers: hard-coded MQTT broker credentials allow remote access

D-Link E15, M32, R15 and R32 devices ship an MQTT broker whose password file, /etc/emDaemon/passwd, contains hard-coded credentials. A remote attacker who knows or extracts those credentials can log into the broker and act on the device's messaging.

_Summary, check and fix written by a model from the sources; labelled as such._
