CVE-2025-6002
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 · uneditedAn unrestricted file upload vulnerability exists in the Product Image section of the VirtueMart backend. Authenticated attackers can upload files with arbitrary extensions, including executable or malicious files, potentially leading to remote code execution or other security impacts depending on server configuration.
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 confidenceAuthenticated attackers can exploit an unrestricted file upload vulnerability in VirtueMart's Product Image backend section to upload files with arbitrary extensions, including executable files. If these malicious files are stored in a web-accessible location, they can be triggered to achieve remote code execution.

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.
-
Identify VirtueMart installationLocate the VirtueMart component in the Joomla installation. Check for the directory 'components/com_virtuemart' or look for VirtueMart entries in the Joomla #__extensions database table.Affected if VirtueMart component is present in the Joomla environment
-
Determine VirtueMart versionFind the version information in the VirtueMart installation, typically in a version.php file within the administrator/components/com_virtuemart folder, or in the Joomla extension manifest. Compare this version against any publicly disclosed affected version ranges for CVE-2025-6002.Affected if The installed VirtueMart version matches a version known to be affected by this vulnerability
-
Confirm access to Product Image backendLog into the Joomla administrator panel and navigate to Components > VirtueMart > Products > Product Images (or similar path for adding product images). Verify that this upload interface exists and is accessible to authenticated users with product management permissions.Affected if The Product Image upload functionality is present and accessible to authenticated administrators
-
Inspect file upload restrictionsExamine the VirtueMart upload handling code (typically in helpers or models directories under com_virtuemart) for the product image upload function. Look for whether file extension validation exists and if it restricts uploads to only safe image formats (jpg, png, gif, webp).Affected if The upload function lacks strict allowlist-based extension validation or permits executable extensions (.php, .phtml, .exe, .js, etc.)
-
Check uploaded file storage locationIdentify where VirtueMart stores uploaded product images (commonly in /images/virtuemart/ or /media/virtuemart/ within the Joomla web root). Verify these directories are web-accessible and files retain their original extensions.Affected if Uploaded files are stored in a web-accessible directory and retain their original file extensions
A user is affected if VirtueMart is installed, the Product Image upload feature lacks proper file extension allowlisting, and uploaded files are stored in web-accessible locations where executable files could be triggered for remote code execution.

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 dataImplement strict allowlist-based file extension validation and MIME type checking for uploads, store uploaded files outside the webroot or with non-executable permissions, and rename uploaded files to strip dangerous extensions.
