Article modification via tokenless administrative requests
Published Jul 31, 2023 · Updated Oct 22, 2024
Cross-site request forgery in DuxCMS 2.1 allows remote attackers to create or edit articles through a victim administrator's browser. The article/AdminContent add and edit handlers accept state-changing POST requests without verifying an anti-CSRF token. Exploitation requires a logged-in administrator to load attacker-controlled content, after which the forged request alters article data under that session.
