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 an arbitrary file upload vulnerability on the media add .php page in the backend of the website in version 5.7.114 of DedeCMS

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

An arbitrary file upload vulnerability exists in the media add .php page in the backend of DedeCMS version 5.7.114, allowing authenticated attackers to upload malicious files to the server. The lack of proper file validation on this upload endpoint enables remote code execution.

MitigationRestrict backend administrative access, implement strict file type validation and content inspection on upload functionality, and apply vendor patches when 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 DedeCMS installation
    Look for DedeCMS characteristic files such as /include/common.inc.php, /dede/login.php (backend), or check page footers for 'DedeCms' branding.
    Affected if The system is running DedeCMS
  2. Verify DedeCMS version
    Check the version file (typically /include/common.inc.php or /data/admin/ver.txt) or access the backend login page which often displays the version.
    Affected if The installed version is exactly 5.7.114
  3. Confirm backend access exists
    Check if the backend directory /dede/ is accessible and whether default admin credentials are in use or if weak credentials are configured.
    Affected if The backend is accessible with valid credentials (required for exploitation)
  4. Locate media upload endpoint
    Navigate to the media management section in the backend, typically found under 'media' or 'files' in the navigation menu, accessing the file that handles uploads (often named media_add.php or similar).
    Affected if The media add functionality is present and accessible
  5. Inspect file validation logic
    Examine the upload handler script source code in the media add page for proper file type checking, content validation, and file extension filtering.
    Affected if File validation is missing, weak, or can be bypassed (allows uploading of executable file types like .php)

The environment is affected if DedeCMS version 5.7.114 is running, the backend is accessible, and the media upload endpoint lacks proper file validation.
