Sensitive component access via missing CSRF protection
Published Sep 23, 2021 · Updated Aug 4, 2024
Cross-site request forgery in YzmCMS 5.5 allows remote attackers to access sensitive application components via crafted requests. The /controller/pay.class.php handler does not enforce a request-origin or anti-CSRF token check, allowing a malicious webpage to submit state-changing requests in a logged-in browser context. Exploitation requires a victim to load attacker-controlled content while authenticated to YzmCMS; the record describes access to sensitive components but does not specify data alteration or service interruption details.
