Title
REDAXO before 5.21.3 CSRF Token Bypass via users/users Privilege Escalation
Summary
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.

Title
REDAXO before 5.21.3 Reflected XSS via opener_link in Media Pool
Summary
REDAXO before 5.21.3 contains a reflected cross-site scripting vulnerability in the backend media pool detail page, where the opener_link parameter is rendered without HTML escaping. Unauthenticated attackers can lure logged-in backend users with media permissions into clicking a crafted link. The injected script can then read the CSRF token and perform actions with the victim's permissions, including code execution via template or module edits when the victim is an administrator.

REDAXO 5.18.0 before 5.21.4 Stored XSS via Unsanitized Mediapool SVG Uploads
Summary
REDAXO from 5.18.0 before 5.21.4 contains a stored cross-site scripting vulnerability because rex_media_service moves uploaded SVG files into the public media folder before sanitizing them. Authenticated users with mediapool upload rights can race the sanitizer or exhaust memory limits to leave script-laden SVGs publicly served, executing scripts in victims' backend sessions.

Title
REDAXO before 5.21.5 Privilege Escalation via Backup Export of Authentication Tables
Summary
REDAXO before 5.21.5 contains a missing authorization vulnerability in the backup addon export that accepts any database table, allowing non-admin users with the backup[export] permission to export rex_user, rex_user_session, and other applications' tables. Attackers can obtain plaintext session ids and stay-logged-in keys to take over admin accounts, or password hashes for offline cracking.

Title
REDAXO before 5.21.5 CSRF via Safe Mode Toggle Parameter
Summary
REDAXO before 5.21.5 contains a cross-site request forgery vulnerability because the backend processes the safemode GET parameter in index.php without validating a CSRF token. Attackers can lure a logged-in administrator into opening a crafted link to disable global safe mode, writing safe_mode: false to config.yml, or enable session safe mode, disabling backend addons.

Title
REDAXO core before 5.21.5 Missing Authorization in rex_api_package API
Summary
REDAXO core before 5.21.5 contains a missing authorization vulnerability in the rex_api_package API function that lets non-admin backend users manage packages with only a valid CSRF token. Attackers holding a token, such as demoted admins with active sessions, can uninstall system addons like structure (dropping their database tables), deactivate, install, or activate packages, and delete non-system packages.

Title
REDAXO before 5.21.3 CSRF Token Bypass via users/users Privilege Escalation
Summary
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.

Title
REDAXO before 5.21.3 Reflected XSS via opener_link in Media Pool
Summary
REDAXO before 5.21.3 contains a reflected cross-site scripting vulnerability in the backend media pool detail page, where the opener_link parameter is rendered without HTML escaping. Unauthenticated attackers can lure logged-in backend users with media permissions into clicking a crafted link. The injected script can then read the CSRF token and perform actions with the victim's permissions, including code execution via template or module edits when the victim is an administrator.

REDAXO 5.18.0 before 5.21.4 Stored XSS via Unsanitized Mediapool SVG Uploads
Summary
REDAXO from 5.18.0 before 5.21.4 contains a stored cross-site scripting vulnerability because rex_media_service moves uploaded SVG files into the public media folder before sanitizing them. Authenticated users with mediapool upload rights can race the sanitizer or exhaust memory limits to leave script-laden SVGs publicly served, executing scripts in victims' backend sessions.

Title
REDAXO before 5.21.5 CSRF via Safe Mode Toggle Parameter
Summary
REDAXO before 5.21.5 contains a cross-site request forgery vulnerability because the backend processes the safemode GET parameter in index.php without validating a CSRF token. Attackers can lure a logged-in administrator into opening a crafted link to disable global safe mode, writing safe_mode: false to config.yml, or enable session safe mode, disabling backend addons.

REDAXO core before 5.21.5 contains a missing authorization vulnerability in the rex_api_package API function that lets non-admin backend users manage packages with only a valid CSRF token. Attackers holding a token, such as demoted admins with active sessions, can uninstall system addons like structure (dropping their database tables), deactivate, install, or activate packages, and delete non-system packages.
