AI-suggested

Upgrade REDAXO core to version 5.21.5 or later, where this missing authorization vulnerability is fixed. No other mitigation is indicated by the vendor advisory.

Description

REDAXO core versions before 5.21.5 have a missing authorization vulnerability in the backup addon export functionality. This flaw allows non-admin users with the backup[export] permission to export sensitive database tables, including rex_user and rex_user_session. Exploiting this, attackers can obtain plaintext session IDs and stay-logged-in keys to hijack admin accounts or acquire password hashes for offline cracking.
