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
In firmware version MS_2.6.9900 of Columbia Weather MicroServer, a stored Cross-site scripting (XSS) vulnerability allows remote authenticated users to inject arbitrary web script via changestationname.php.

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

A stored Cross-site scripting (XSS) vulnerability in the changestationname.php component of Columbia Weather MicroServer firmware MS_2.6.9900 allows authenticated remote users to inject arbitrary JavaScript through the station name parameter. The malicious payload is persisted and executed when other users access the affected interface.

MitigationImplement proper input validation and output encoding on the changestationname.php endpoint to neutralize malicious script content, and consider adding Content-Security-Policy headers to provide defense-in-depth.

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 the firmware version
    Access the device admin interface or check system information page to find the installed firmware version. Look for a version or build number field typically found under Settings, System Info, or About sections.
    Affected if The firmware version is exactly ms_2.6.9900
  2. Confirm changestationname.php exists
    Attempt to access the /changestationname.php endpoint via HTTP/HTTPS on the device's web interface. This is typically found under weather station configuration or settings menus.
    Affected if The endpoint responds (returns a page or error) indicating the component is present
  3. Check authentication status
    Log into the weather station admin interface using valid credentials. The vulnerability requires an authenticated session to exploit the station name parameter.
    Affected if You can successfully authenticate to the device admin panel
  4. Inspect station name rendering
    Navigate to the station name configuration page where the name is displayed. View the page source or observe how the station name appears in the web interface to check if it is reflected without proper encoding.
    Affected if The station name value appears in HTML output without being HTML-encoded (visible as raw script tags or unescaped special characters)

You are affected if the device runs firmware version ms_2.6.9900 AND the changestationname.php component is accessible with authentication, AND the station name is rendered without HTML entity encoding.

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.
