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
ASUS RT-AC* and RT-N* devices with firmware before 3.0.0.4.380.7378 allow remote authenticated users to discover the Wi-Fi password via WPS_info.xml.

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

This is an information disclosure vulnerability in ASUS RT-AC and RT-N routers. Authenticated remote users can access WPS_info.xml to retrieve the Wi-Fi password in plaintext. The vulnerability requires valid credentials but grants access to sensitive Wi-Fi credentials to any authenticated user.

MitigationUpdate ASUS router firmware to version 3.0.0.4.380.7378 or later to patch the vulnerability. As an interim measure, restrict administrative access to trusted IP addresses only.

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. Identify router model
    Log into the router web interface or check the device label to confirm the model is ASUS RT-AC or RT-N series
    Affected if Router model is ASUS RT-AC or RT-N series
  2. Check firmware version
    In the router web interface, navigate to Administration > Firmware Upgrade or similar section to view the installed firmware version
    Affected if Firmware version is 3.0.0.4.380.7266
  3. Verify remote administration is enabled
    In the router web interface, check Administration > System > Remote Management or similar setting to see if remote access with authentication is enabled
    Affected if Remote web management with authentication is enabled and accessible from WAN
  4. Test WPS_info.xml access
    Using valid router credentials, attempt to access http://routerIP/WPS_info.xml via HTTP from a remote location
    Affected if WPS_info.xml is accessible and displays Wi-Fi password in plaintext

User is affected if they have an ASUS RT-AC or RT-N router running firmware version 3.0.0.4.380.7266 with remote administration enabled, and the WPS_info.xml endpoint is accessible to authenticated users.
