An issue was discovered on Actiontec WCB6200Q before 1.1.10.20a devices. The admin login session cookie is insecurely generated making admin session hijacking possible. When an admin logs in, a session cookie is generated using the time of day rounded to 10ms. Since the web server returns its current time of day in responses, it is possible to step backward through possible session values until a working one is found. Once a working session ID is found, an attacker then has admin control of the device and can add a secondary SSID to create a backdoor to the network.

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."

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.
