CVE-2025-9415
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 · uneditedA vulnerability was identified in GreenCMS up to 2.3.0603. This affects an unknown part of the file /index.php?m=admin&c=media&a=fileconnect. The manipulation of the argument upload[] leads to unrestricted upload. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. This vulnerability only affects products that are no longer supported by the maintainer.
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 confidenceGreenCMS contains an unrestricted file upload vulnerability in the admin media module (fileconnect action). The vulnerability allows manipulation of the upload[] parameter to upload arbitrary files without proper validation, leading to potential remote code execution. The CVSS 9.8 score reflects the critical severity of unauthenticated file upload allowing complete system compromise.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate GreenCMS installationSearch for GreenCMS files on the server. Common paths include /var/www/html/, /www/, or C:\inetpub\wwwroot\. Look for directories containing 'green' or 'Greencms' in the name, or files like index.php that reference 'GreenCMS'.Affected if GreenCMS files are found on the server
-
Identify the installed GreenCMS versionOpen the main GreenCMS index file or a typically versioned file like version.php, changelog.txt, or readme.txt in a web browser or text editor. Compare the displayed version number to the affected range of <= 2.3.0603.Affected if The installed version is 2.3.0603 or lower
-
Verify admin interface is accessibleAttempt to access the GreenCMS admin login page. Common paths include /admin/, /administrator/, or /admin.php. Check if the page loads and authentication is available.Affected if The admin interface is reachable without network restrictions
-
Confirm media fileconnect functionality existsCheck for the presence of the media fileconnect module in the admin panel. Look for menu items labeled 'Media', 'File Manager', or 'File Connect' in the admin dashboard, or search the source code for 'fileconnect' or 'upload' functionality.Affected if The media fileconnect feature is present and enabled in the admin panel
-
Check if file upload functionality accepts arbitrary file typesIf you have admin access, navigate to the media fileconnect upload feature. Attempt to upload a test file with a non-standard extension (such as .php, .exe, or .phtml) via the upload[] parameter to verify if unrestricted uploads are possible.Affected if The upload accepts files with executable extensions without validation
You are affected if GreenCMS version 2.3.0603 or lower is installed, the admin interface is accessible, and the media fileconnect upload functionality accepts arbitrary file types.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince GreenCMS is end-of-life with no vendor patches available, migrate to a actively supported CMS. If continued use is mandatory, implement web application firewall rules to restrict file upload types, disable script execution in upload directories, and add proper file type validation at the web server level.
