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
There is a file upload XSS vulnerability in Generex CS141 below 2.06 version. The web application allows file uploading, making it possible to upload a file with HTML content. When HTML files are allowed, XSS payload can be injected into the uploaded file.

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

There is a stored Cross-Site Scripting (XSS) vulnerability in Generex CS141 web application versions below 2.06. The application allows file uploads and permits HTML files to be uploaded without proper sanitization or validation. An attacker can upload a malicious HTML file containing XSS payloads that will execute when other users view or access the uploaded file.

MitigationUpgrade to Generex CS141 version 2.06 or later which contains the fix. Additionally, implement strict file type validation to disallow HTML file uploads, or sanitize uploaded file content to strip potentially malicious scripts before storage.

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. Determine the installed firmware version
    Access the Generex CS141 web interface and navigate to System > Status, System > Information, or the About page to locate the firmware version. If direct device access is available, check the version displayed in the admin panel or device status screen.
    Affected if The installed firmware version is below 2.06
  2. Verify if file upload functionality exists
    Log into the CS141 web application and explore the navigation menus for file upload capabilities. Look for sections such as File Management, Backup/Restore, Configuration Upload, Dashboard widgets, or any feature that accepts file uploads.
    Affected if A file upload feature is present and accessible in the web application
  3. Test if HTML file uploads are permitted
    Through the identified upload feature, attempt to upload a test file with an .html extension. Submit the file through the upload form and confirm whether the server accepts and stores the HTML file without rejecting it based on file type.
    Affected if HTML files can be uploaded and stored on the server without being blocked or sanitized

The environment is affected if the Generex CS141 firmware version is below 2.06 and the file upload feature allows HTML files to be uploaded and stored.
