Estado: ModificadaMedia (4)—

The Telus Wi-Fi Hub (PRV65B444A-S-TS) with firmware version 3.00.20 is vulnerable to an authenticated arbitrary file read. An authenticated user with physical access to the device can read arbitrary files from the device by preparing and connecting a specially prepared USB drive to the device, and making a series of crafted requests to the device's web interface.
