Executive Summary

This is an unauthenticated arbitrary file upload vulnerability in the Fabrik Joomla extension. It affects the list email plugin in versions before 4.7.2. Attackers can upload non-executable files directly to the web root without authentication.

Detection Guidance

Check for unauthorized file uploads in the Fabrik list email plugin directory. Inspect web server logs for POST requests to /plugins/fabrik_list/email/email.php with file upload parameters. Look for unexpected files in the web root, especially with extensions not typically allowed.

An attacker could upload malicious files to your server, potentially leading to remote code execution, defacement, or further compromise of your Joomla site and hosting environment.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR's integrity and confidentiality requirements and HIPAA's security rules for protected health information.

Mitigation Strategies

Update Fabrik to version 4.7.2 or later immediately. Temporarily disable the list email plugin if an update is not immediately possible. Review and restrict file upload permissions in the plugin directory to prevent unauthorized file writes.
