Arris DG860A, TG862A, and TG862G devices with firmware TS0703128_100611 through TS0705125D_031115 have predictable technician passwords, which makes it easier for remote attackers to obtain access via the web management interface, related to a "password of the day" issue.

Arris DG860A, TG862A, and TG862G devices with firmware TS0703128_100611 through TS0705125D_031115 have a hardcoded administrator password derived from a serial number, which makes it easier for remote attackers to obtain access via the web management interface, SSH, TELNET, or SNMP.

Cross-site scripting (XSS) vulnerability in adv_pwd_cgi in the web management interface on Arris DG860A, TG862A, and TG862G devices with firmware TS0703128_100611 through TS0705125D_031115 allows remote attackers to inject arbitrary web script or HTML via the pwd parameter.

Cross-site request forgery (CSRF) vulnerability in adv_pwd_cgi in the web management interface on Arris DG860A, TG862A, and TG862G devices with firmware TS0703128_100611 through TS0705125D_031115 allows remote attackers to hijack the authentication of arbitrary users.

Arris DG860A and DG1670A devices have predictable default WPA2 PSKs that could lead to unauthorized remote access. (They use the first 6 characters of the SSID and the last 6 characters of the BSSID, decrementing the last digit.)
