By using SOAP-based Enhanced WSD protocol there is a possibility that the device will respond without user authentication and enable data acquisition of the registered address book despite prior settings to require user authentication.
2. Impact on our products  
We will provide firmware for MFPs to close the gap. It is expected that there is no impact from this vulnerability, unless there is an external intrusion into the customer's network. Security measures such as Firewall are recommended. We advise to disable the Enhanced WSD protocol and to enable the Enhanced WSD over SSL protocol.
