A pair of flaws in ASUS routers for the home could allow an attacker to eavesdrop on all of the traffic and data that flows through them. The bugs are specifically found in the RT-AC1900P whole-home Wi-Fi model, within the router s firmware update functionality. The two flaws allow man-in-the-middle attacks that would give an attacker access to all data flowing through the router. Owners are urged to apply the updates as soon as they can.
