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
Advanced_System_Content.asp in the ASUS RT series routers with firmware before 3.0.0.4.374.5517, when an administrator session is active, allows remote authenticated users to obtain the administrator user name and password by reading the source code.

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 ASUS RT series routers with firmware before 3.0.0.4.374.5517 have an information disclosure vulnerability in the Advanced_System_Content.asp web page. When an administrator session is active, any authenticated user can view the page source to obtain the administrator username and password in plaintext.

MitigationUpdate router firmware to version 3.0.0.4.374.5517 or later. Restrict administrative access to only trusted users until the update is applied.

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 and firmware version
    Log into the ASUS router admin web interface and navigate to System Setup or Administration > Firmware Version. Alternatively, check the label on the router or use the router's status page.
    Affected if The router model is any of the following: RT-AC66U, RT-AC68U, RT-N10E, RT-N14U, RT-N16, RT-N56U, RT-N65U, RT-N66U, and the firmware version matches one listed in the affected versions.
  2. Compare installed firmware version to affected list
    Note the exact firmware version string displayed on the router status page and compare it to the affected versions provided: RT-AC66U: 3.0.0.4.140, 3.0.0.4.220, 3.0.0.4.246, 3.0.0.4.260, 3.0.0.4.270, 3.0.0.4.354; RT-AC68U: 3.0.0.4.374.4755, 3.0.0.4.374_4561, 3.0.0.4.374_4887; RT-N10E: 2.0.0.7, 2.0.0.10, 2.0.0.16, 2.0.0.19, 2.0.0.20, 2.0.0.24, 2.0.0.25; RT-N14U: 3.0.0.4.322, 3.0.0.4.356; RT-N16: 1.0.1.9, 1.0.2.3, 3.0.0.3.108, 3.0.0.3.162, 3.0.0.3.178, 3.0.0.4.220, 3.0.0.4.246, 3.0.0.4.260, 3.0.0.4.354, 7.0.2.38b; RT-N56U: 1.0.1.4, 1.0.1.4o, 1.0.1.7c, 1.0.1.7f, 1.0.1.8j, 1.0.1.8l, 1.0.1.8n, 3.0.
    Affected if The installed firmware version exactly matches one of the versions listed above.
  3. Access Advanced_System_Content.asp page
    While logged into the router as any authenticated user (administrator or guest), navigate to the URL path /Advanced_System_Content.asp on the router web interface, or find this page in the administration section.
    Affected if The page loads successfully and is accessible without error.
  4. View page source for credential exposure
    Right-click on the loaded Advanced_System_Content.asp page and select View Page Source, or use browser developer tools to inspect the HTML source.
    Affected if The page source contains plaintext administrator username and password values in the HTML, form fields, or JavaScript variables.

You are affected if your ASUS RT series router runs any of the listed firmware versions and the Advanced_System_Content.asp page exposes plaintext credentials in its source code when accessed by an authenticated user.
