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
Document Management System developed by Excellent Infotek has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attackers to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.

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 · high confidence

The Excellent Infotek Document Management System contains an arbitrary file upload vulnerability in its upload functionality. Attackers can bypass authentication to upload malicious files, including web shells, directly to the web server. Successful exploitation grants remote code execution capabilities on the underlying system.

MitigationRestrict file upload functionality to authenticated users only and implement strict allowlist-based file type validation. Store uploaded files outside the web root with randomized filenames, disable script execution in upload directories, and apply proper access controls.

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 if Excellent Infotek Document Management System is installed
    Look for the Document Management System application in your web server's webroot, typically in a directory named 'documents' or similar. Check your installed applications list or web server configuration for this specific software.
    Affected if The system is running the Excellent Infotek Document Management System application
  2. Verify the file upload feature is exposed
    Access the upload functionality endpoint (typically /upload.php, /documents/upload.php, or similar path on the Document Management System) via HTTP request to confirm the upload interface is reachable.
    Affected if The upload endpoint responds and accepts requests without authentication
  3. Check if uploaded files are stored within the webroot
    Inspect the application's configuration files (such as config.php or settings.php) to determine the upload directory path. Verify whether this directory is located inside the publicly accessible webroot.
    Affected if The configured upload directory path is inside the web-accessible directory tree
  4. Test for unrestricted file type handling
    Attempt to upload a non-image, non-document file type (such as a .php file with test content) to the upload endpoint using a tool like curl or Burp Suite to see if it is accepted and stored.
    Affected if The system accepts and stores files with extensions other than expected document types (pdf, doc, docx, images) without validation
  5. Confirm uploaded files retain executable extensions
    After an upload test, verify the stored file in the upload directory retains its original extension and is directly accessible via a web browser URL.
    Affected if Uploaded files with potentially malicious extensions (php, asp, jsp) are accessible via web URL and retain their original extension

A user is affected if the Excellent Infotek Document Management System is installed with its file upload feature accessible without authentication and uploads are stored within the webroot without proper file type restrictions.

Mitigation

Restrict file upload functionality to authenticated users only and implement strict allowlist-based file type validation. Store uploaded files outside the web root with randomized filenames, disable script execution in upload directories, and apply proper access controls.
