Administrative deletion via tokenless cross-origin request
Published Mar 13, 2024 · Updated Apr 15, 2025
CSRF in DedeCMS 5.7 allows remote attackers to trigger an administrative deletion through /dede/stepselect_main.php after user interaction. The endpoint accepts action=del and an object id from a cross-origin request without requiring an anti-CSRF token. Exploitation requires an authenticated administrator to load attacker-controlled content, after which the selected administrative object is deleted.
