Executive Summary

This vulnerability affects Balbooa Forms versions before 2.4.3.4 in Joomla. It allows tampering with file metadata during form submissions. The system processes JSON arrays for upload fields but only checks if IDs are numeric. It directly trusts client-supplied filenames and display names, which can lead to cross-session claiming, metadata tampering, and path traversal risks.

Detection Guidance

Check Joomla extensions for Balbooa Forms versions below 2.4.3.4. Inspect file upload handling in forms for improper filename validation or path traversal attempts in submitted data.

Impact Analysis

An attacker could manipulate file metadata to claim files across different sessions, alter file paths to access unauthorized directories, or inject malicious filenames. This could result in unauthorized file access, data leaks, or system compromise depending on the Joomla environment configuration.

Compliance Impact

This vulnerability could lead to unauthorized access or tampering with sensitive data, violating GDPR's integrity and confidentiality principles or HIPAA's security requirements for protected health information. Compliance may be compromised if unauthorized file access occurs.

Mitigation Strategies

Update Balbooa Forms to version 2.4.3.4 or later. Review and restrict file upload permissions. Implement strict input validation for filenames and paths in form submissions.
