Executive Summary

REDAXO before version 5.21.6 has an authorization bypass flaw where editors without the version[live_version] permission can modify live article versions. This bypasses working version enforcement, allowing authenticated editors to add, edit, delete, toggle, or reorder live slices through functions like content/functions, slice IDs, content_slice_status, content_move_slice, history restore, or content_copy. The vulnerability circumvents approval workflows.

Impact Analysis

This vulnerability allows unauthorized users with editor privileges to modify published content directly, bypassing approval processes. Attackers could alter live articles, reorder content, delete slices, or restore historical versions without proper permissions. This undermines content integrity and could lead to misinformation or unauthorized changes in a live environment.

Compliance Impact

This vulnerability could violate compliance requirements that mandate strict access controls and audit trails for content modifications, such as GDPR's data integrity principles or HIPAA's access controls for sensitive data. Unauthorized changes to published content may result in non-compliance with data protection regulations due to lack of proper authorization enforcement.

Mitigation Strategies
  • Upgrade REDAXO to version 5.21.6 or later to address the authorization bypass vulnerability.
  • Review user permissions to ensure editors without live_version permission cannot modify published content.
  • Disable the working version as an approval mechanism if it is not required for your workflow.
  • Monitor content changes and approval workflows for unauthorized modifications.
