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 security vulnerability has been detected in technical-laohu mpay up to 1.2.4. The impacted element is an unknown function of the component QR Code Image Handler. Such manipulation of the argument codeimg leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed publicly and may be used.

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

Unrestricted file upload vulnerability in the QR Code Image Handler component of technical-laohu mpay up to v1.2.4. The 'codeimg' parameter accepts arbitrary file uploads without proper validation, allowing attackers to upload malicious files (e.g., web shells) to the server. This is exploitable remotely with no authentication required.

MitigationImmediately restrict upload functionality to validated file types (e.g., images only), implement server-side validation, rename uploaded files, store them outside webroot, and disable script execution in the upload directory. Consider disabling the affected component until a patch is available.

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 installed mpay version
    Locate the application installation directory and check version file, or query the application API/interface for version information
    Affected if The installed version is 1.2.4 or lower
  2. Locate QR Code Image Handler component
    Search for files related to QR code handling - typically in modules, handlers, or components directories under the web application root
    Affected if The QR Code Image Handler component exists and is accessible via web requests
  3. Test upload endpoint accessibility
    Send a POST request to the QR Code Image Handler endpoint with the 'codeimg' parameter containing a test file (e.g., a simple text file)
    Affected if The endpoint accepts file uploads without returning validation errors or rejecting the upload
  4. Inspect web root for unauthorized uploads
    Search upload directories (often /uploads, /images, or /temp) for unexpected file types such as .php, .asp, .jsp, .exe, or other executable extensions
    Affected if Suspicious executable files are found in upload directories, especially if they were not intentionally placed there

You are affected if technical-laohu mpay version 1.2.4 or lower is installed and the QR Code Image Handler component is accessible, as the unrestricted upload via the 'codeimg' parameter allows remote attackers to upload malicious files without authentication.

Upgrade available Upgrade to a release after 1.2.4
Interim mitigation

Immediately restrict upload functionality to validated file types (e.g., images only), implement server-side validation, rename uploaded files, store them outside webroot, and disable script execution in the upload directory. Consider disabling the affected component until a patch is available.
