CVE-2021-20175

Estado: ModificadaAlta (7.5)—

Netgear Nighthawk R6700 version 1.0.4.120 does not utilize secure communication methods to the SOAP interface. By default, all communication to/from the device's SOAP Interface (port 5000) is sent via HTTP, which causes potentially sensitive information (such as usernames and passwords) to be transmitted in cleartext
