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
A Cross-Site Scripting (XSS) vulnerability exists in the web-based configuration interface of Zucchetti Axess access control devices, including XA4, X3/X3BIO, X4, X7, and XIO / i-door / i-door+. The vulnerability is caused by improper sanitization of user-supplied input in the dirBrowse parameter of the /file_manager.cgi endpoint.

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 XSS vulnerability exists in the web-based configuration interface of Zucchetti Axess access control devices (XA4, X3/X3BIO, X4, X7, XIO/i-door/i-door+). The dirBrowse parameter in /file_manager.cgi fails to sanitize user-supplied input, allowing injection of malicious JavaScript that executes in the context of other users' sessions.

MitigationImplement strict input validation and output encoding on the dirBrowse parameter in /file_manager.cgi; applyContextual escaping for all user-controlled data rendered in HTML. If available, apply vendor firmware updates.

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 Zucchetti Axess device model
    Check the device label, management interface header, or system information page for the model number. Affected models include XA4, X3/X3BIO, X4, X7, and XIO/i-door/i-door+.
    Affected if The device is one of these specific models.
  2. Confirm web-based management interface is enabled
    Access the device IP address via HTTP/HTTPS in a web browser. Look for the Zucchetti Axess login page or configuration interface.
    Affected if The web interface is accessible and shows a Zucchetti Axess login or configuration page.
  3. Verify /file_manager.cgi endpoint exists
    Navigate to http[s]://[device-ip]/file_manager.cgi or check if this endpoint responds (may require authentication first).
    Affected if The /file_manager.cgi endpoint exists and is accessible on the device.
  4. Check for dirBrowse parameter usage
    Examine the HTTP requests when using the file manager interface, or inspect the page source for the dirBrowse parameter in forms or URLs.
    Affected if The dirBrowse parameter is present in requests or page source within the file manager functionality.
  5. Assess input sanitization on dirBrowse
    Submit a test value containing characters like <script>alert(1)</script> or '" onclick= in the dirBrowse parameter and observe if the value is reflected back unescaped in the response.
    Affected if User-supplied input in the dirBrowse parameter is reflected in the response without proper HTML encoding or sanitization.

If the device is one of the affected Zucchetti Axess models (XA4, X3/X3BIO, X4, X7, XIO/i-door/i-door+) and the web interface with /file_manager.cgi is accessible, the environment is potentially affected by this stored XSS vulnerability.
