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
Cross-site scripting (XSS) vulnerability on ASUS Japan WL-330NUL devices with firmware before 3.0.0.42 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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 · moderate confidence

This is a stored Cross-Site Scripting (XSS) vulnerability in the web management interface of the ASUS WL-330NUL wireless router (Japan region). Remote attackers can inject arbitrary JavaScript or HTML through unsanitized input vectors, which executes when administrative users access affected pages in the router's web interface.

MitigationUpgrade the router's firmware to version 3.0.0.42 or later. If firmware updates are unavailable, restrict administrative access to trusted networks only and consider network segmentation to limit exposure.

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
    Access the router's web admin panel (typically at 192.168.1.1) or check the device label to confirm the model is WL-330NUL (Japan region variant)
    Affected if The router model is not WL-330NUL (Japan region)
  2. Check firmware version
    Log into the router web interface and navigate to the Firmware Upgrade or Administration section to view the current firmware version
    Affected if Firmware version is 3.0.0.41 or lower (the vulnerable version)
  3. Verify web management interface accessibility
    Confirm the router's HTTP/HTTPS management interface is reachable on the local network
    Affected if The web management interface is exposed and accessible
  4. Check for unsanitized input vectors
    Review web interface input fields (in functions like wireless settings, network name, or admin configuration) for lack of input sanitization - this typically requires source code access or manual testing with benign script tags
    Affected if Input fields in the web interface do not sanitize special characters like <script> tags

You are affected if you have an ASUS WL-330NUL (Japan region) router running firmware version 3.0.0.41 or lower with its web management interface accessible.

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 data
Upgrade available Upgrade to a release after 3.0.0.41
Interim mitigation

Upgrade the router's firmware to version 3.0.0.42 or later. If firmware updates are unavailable, restrict administrative access to trusted networks only and consider network segmentation to limit exposure.
