CVE-2007-4388
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · unedited2wire 1701HG and 2071 Gateway routers, with 5.29.51 and possibly 3.17.5 software, have a blank password by default.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe 2wire 1701HG and 2071 Gateway routers with firmware versions 5.29.51 (and possibly 3.17.5) ship from the factory with a blank/empty default password, allowing unauthenticated remote attackers to gain full administrative access to the router's management interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm router modelLog into the router's web interface or check the device label to verify the exact model number is 2wire 1701HG or 2wire 2071Affected if The router is a 2wire 1701HG or 2071 Gateway model
-
Check admin password statusAccess the router's administrative interface (typically at 192.168.1.1 or 192.168.0.1), navigate to the password or administrator settings, and verify whether the administrative password is blank, empty, or set to defaultAffected if The admin password is blank, empty, or still at factory default with no password set
-
Verify remote management settingIn the router's admin interface, locate the remote management or remote access settings (often under Advanced, Security, or Administration sections) and check if remote management is enabledAffected if Remote management is enabled and accessible from the WAN/internet
A user is affected if they own a 2wire 1701HG or 2071 router with a blank or unset administrative password, especially if remote management is enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately change the default blank password to a strong, unique password through the router's administrative web interface, and ensure remote management is disabled or restricted to trusted IPs if not needed.
