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 vulnerability was found in Fujian mwcms 1.0.0. It has been declared as critical. Affected by this vulnerability is the function uploadeditor of the file /uploadeditor.html?action=uploadimage of the component Image Upload. The manipulation of the argument upfile leads to unrestricted upload. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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

Fujian mwcms 1.0.0 contains an unrestricted file upload vulnerability in the uploadeditor function at /uploadeditor.html?action=uploadimage. The 'upfile' argument accepts files without proper validation, allowing remote attackers to upload arbitrary files including executable scripts. This can lead to remote code execution if web shells are uploaded to accessible directories.

MitigationImplement strict server-side file type validation using both magic byte checks and extension whitelist filtering. Store uploaded files outside the webroot or rename them to prevent direct execution, and disable script execution in the upload directory.

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. Confirm Mwcms version
    Locate the Mwcms installation and identify its version number, typically found in the main application files, admin panel, or footer of the admin pages
    Affected if The installed version is exactly 1.0.0
  2. Verify uploadeditor endpoint exists
    Check if the file /uploadeditor.html exists in the web application root directory
    Affected if The uploadeditor.html file is present and accessible via web browser
  3. Check if upload functionality is accessible
    Access the URL /uploadeditor.html?action=uploadimage and verify the page loads with a file upload form
    Affected if The upload form is displayed and accepts file input via the 'upfile' parameter
  4. Inspect upload directory configuration
    Examine the web server configuration and application settings to determine where uploaded files are stored and whether script execution is restricted
    Affected if Uploaded files are stored within the webroot in a directory that allows script execution

A user is affected if they are running Mwcms version 1.0.0 with the uploadeditor.html endpoint accessible and file uploads enabled without proper validation controls.
