Arris Tg1682g Firmware

On Arris Touchstone Telephony Gateway TG1682G 9.1.103J6 devices, a logout action does not immediately destroy all state on the device related to the validity of the "credential" cookie, which might make it easier for attackers to obtain access at a later time (e.g., "at least for a few minutes"). NOTE: there is no documentation stating that the web UI's logout feature was supposed to do anything beyond removing the cookie from one instance of a web browser; a client-side logout action is often not intended to address cases where a person has made a copy of a cookie outside of a browser.Show less

Arris Touchstone Telephony Gateway TG1682G 9.1.103J6 devices are distributed by some ISPs with a default password of "password" for the admin account that is used over an unencrypted http://192.168.0.1 connection, which might allow remote attackers to bypass intended access restrictions by leveraging access to the local network. NOTE: one or more user's guides distributed by ISPs state "At a minimum, you should set a login password."Show less

NOTE: the scope of this CVE does NOT include the concept of "Unnecessary Services" in general; the scope is only a single service that is unnecessarily exposed, leading to remote code execution. The details of that service might be disclosed at a later date.Show less
