In firmware versions 2.7.7 and earlier, the Arris BGW210‑700 gateway fails to enforce any server‑side authentication on its /cgi-bin/.ha management endpoints, relying solely on client‑side CSS/JavaScript gating that can be bypassed by any HTTP client. This allows unauthenticated attackers on the LAN to read sensitive configuration data, modify persistent device settings, or trigger backend diagnostic operations. The issue appears systemic across the CGI handler chain.

Arris DG860A, TG862A, and TG862G devices with firmware TS0703128100611 through TS0705125D031115 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.

Unspecified vulnerability in the management portal in ARRIS VAP2500 before FW08.41 allows remote attackers to execute arbitrary commands via unknown vectors.

The management portal in ARRIS VAP2500 before FW08.41 allows remote attackers to obtain credentials by reading the configuration files.

ARRIS VAP2500 before FW08.41 does not properly validate passwords, which allows remote attackers to bypass authentication.
