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
NUP Portal developed by NewType Infortech has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to directly upload files. If the attacker manages to bypass the file extension restrictions, they could upload a webshell and execute it on the server side.

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

NUP Portal by NewType Infortech lacks authentication on its file upload endpoint, allowing any remote attacker to upload files without credentials. If an attacker bypasses the existing file extension restrictions, they can upload a malicious webshell and achieve remote code execution on the server.

MitigationImplement proper authentication and authorization checks on all file upload endpoints, combined with strict server-side file validation (not just extension checking) including magic byte verification and executable file type blocking.

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 NUP Portal installation
    Search the server for NUP Portal files or check running web services for 'NUP Portal' or 'NewType Infortech' in application headers or installed software lists
    Affected if NUP Portal by NewType Infortech is installed and running
  2. Identify file upload endpoint
    Locate the file upload functionality in the web application by reviewing application URLs, checking for common upload paths like /upload, /file/upload, or /api/upload in the application structure
    Affected if A file upload endpoint exists and is accessible via HTTP/HTTPS
  3. Test upload endpoint authentication
    Send a request to the upload endpoint without providing any authentication credentials (cookies, tokens, or session headers) and observe whether the request is accepted or rejected
    Affected if The upload endpoint accepts requests without requiring authentication
  4. Check file extension validation configuration
    Review the application configuration files or upload handler code to determine what file extensions are allowed, and whether extension checking is the only validation method
    Affected if File extension restrictions exist but no additional server-side validation (such as magic byte verification) is configured
  5. Verify uploaded file storage location
    Check if uploaded files are stored in a web-accessible directory (such as /uploads, /files, or web root) that allows execution of uploaded content
    Affected if Uploaded files are stored in a directory that serves executable file types

The environment is affected if NUP Portal is running and the file upload endpoint accepts unauthenticated requests, allowing remote upload of executable files to a web-accessible location.
