Miele: Multiple Vulnerabilities in XGW 3000 ZigBee Gateway
Miele XGW 3000 is a ZigBee-TCP/IP gateway. The gateway connects Miele ZigBee-Appliances (called Miele@home) with local customer TCP/IP-Network and allows visualizing the appliance state on the web interface of the gateway, Miele SuperVision capable appliance, smartphone/tablet app or home automatization device. An external security researcher reported two vulnerabilities in XGW 3000 gateway and provided a Proof-of-Concept. The combined exploitation of both vulnerabilities allow the circumvention of the authentication mechanisms of the XGW3000. The Miele PSIRT managed to reproduce the findings and successfully exploited the gateway. Therefore, the existence of all vulnerabilities has been confirmed.
