Administrator account creation via tokenless cross-origin POST
Published Jul 14, 2021 · Updated Aug 4, 2024
Cross-site request forgery in ThinkCMF before 6.0.8 allows remote attackers to create an administrator account through an authenticated browser. The admin/user/addpost.html endpoint accepts attacker-chosen account and role fields in a cross-origin POST without requiring a valid request token. Exploitation requires a logged-in administrator to visit attacker-controlled content, after which the new credentials grant administrative control.
