CommScope ARRIS TR4400 devices with firmware through A1.00.004-180301 are vulnerable to an authentication bypass to the administrative interface because they include the current base64 encoded password within http://192.168.1.1/login.html. Any user connected to the Wi-Fi can exploit this.

ARRIS DG950A 7.10.145 and DG950S 7.10.145.EURO devices allow remote attackers to discover credentials via iso.3.6.1.4.1.4491.2.4.1.1.6.1.1.0 and iso.3.6.1.4.1.4491.2.4.1.1.6.1.2.0 SNMP requests.

ARRIS SBG6580-2 D30GW-SEAEAGLE-1.5.2.5-GA-00-NOSH devices allow remote attackers to discover credentials via iso.3.6.1.4.1.4491.2.4.1.1.6.1.1.0 and iso.3.6.1.4.1.4491.2.4.1.1.6.1.2.0 SNMP requests.

The web component on ARRIS TG2492LG-NA 061213 devices allows remote attackers to obtain sensitive information via the /snmpGet oids parameter.

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.

Arris TG1682G devices with Comcast TG1682_2.0s7_PRODse 10.0.59.SIP.PC20.CT software allow Unauthenticated Stored XSS via the actionHandler/ajax_managed_services.php service parameter.

The Comcast firmware on Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421733-160420a-CMCST); Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421746-170221a-CMCST); and Arris TG1682G (eMTA&DOCSIS version 10.0.132.SIP.PC20.CT, software version TG1682_2.2p7s2_PROD_sey) devices makes it easy for remote attackers to determine the hidden SSID and passphrase for a Home Security Wi-Fi network.

The Comcast firmware on Cisco DPC3939B (firmware version dpc3939b-v303r204217-150321a-CMCST) devices allows configuration changes via CSRF.

The Comcast firmware on Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421733-160420a-CMCST); Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421746-170221a-CMCST); Cisco DPC3939B (firmware version dpc3939b-v303r204217-150321a-CMCST); Cisco DPC3941T (firmware version DPC3941_2.5s3_PROD_sey); and Arris TG1682G (eMTA&DOCSIS version 10.0.132.SIP.PC20.CT, software version TG1682_2.2p7s2_PROD_sey) devices does not include the HTTPOnly flag in a Set-Cookie header for administration applications, which makes it easier for remote attackers to obtain potentially sensitive information via script access to cookies.
