Netgear Nighthawk R6700 version 1.0.4.120 does not utilize secure communication methods to the web interface. By default, all communication to/from the device's web interface is sent via HTTP, which causes potentially sensitive information (such as usernames and passwords) to be transmitted in cleartext.
