authentication. This could allow unauthorized modification of the device 
firmware. The unauthorized firmware could impact the confidentiality and 
integrity of data sent to and received from the device. The unauthorized 
firmware could also cause a Denial of Service (DoS) to the device.

RESOLUTION

It is recommended that the device be secured as described in the document 
below, including disabling the Printer Firmware Update:
