Short explanation
REDAXO versions prior to 5.21.3 contain a cross-site request forgery vulnerability in the backend user administration page. Attackers can target logged-in users to grant administrator rights or lock out accounts.
This vulnerability allows critical privilege escalation and account administration takeover via unauthenticated requests, compromising system integrity.
What should be done?
- Follow vendor advisories and updates
- Update REDAXO core to version 5.21.3 or later
- Audit user privileges and sessions

Chain of evidence and sources
REDAXO 5.21.3 öncesi sürümlerde, arka uç kullanıcı yönetiminde CSRF token kontrol atlamasına neden olan bir güvenlik açığı bulunmaktadır.
Saldırganlar, users[] iznine sahip oturum açmış bir kullanıcıyı hazırlanan bir bağlantıya yönlendirerek yönetici hakları verebilir veya hesapları kilitleyebilir.
Show the technical text from the sources
REDAXO before 5.21.3 contains a cross-site request forgery vulnerability in the backend user administration page (users/users) because the CSRF token check only runs when the save parameter is set, while the update path triggered by FUNC_UPDATE does not require it. Attackers can lure a logged-in backend user with the users[] permission to a crafted GET link to grant administrator rights, deactivate accounts, or lock out the sole administrator.
