Template modification via unvalidated cross-origin POST
Published Mar 13, 2024 · Updated Aug 5, 2024
Cross-site request forgery in DedeCMS 5.7 allows remote attackers to alter single-page templates through an authenticated administrator. The templets_one_edit.php saveedit branch accepts attacker-supplied POST fields without validating a CSRF token, updates the sgpage record, and regenerates its HTML file. Exploitation requires an authenticated administrator to load attacker-controlled HTML, and the demonstrated consequence is unauthorized template-content modification.
