New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

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.
