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 · unedited
2wire 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 confidence

The 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.

MitigationImmediately 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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm router model
    Log into the router's web interface or check the device label to verify the exact model number is 2wire 1701HG or 2wire 2071
    Affected if The router is a 2wire 1701HG or 2071 Gateway model
  2. Check admin password status
    Access 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 default
    Affected if The admin password is blank, empty, or still at factory default with no password set
  3. Verify remote management setting
    In 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 enabled
    Affected 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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Immediately 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.
