Netgear Nighthawk R6700 version 1.0.4.120 does not utilize secure communication methods to the web interface.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
