Administrator account creation via missing CSRF validation

Published Mar 15, 2026 · Updated Mar 16, 2026

Cross-site request forgery in Next Click Ventures RealtyScript 4.0.2 allows attackers to create unauthorized user accounts. The /admin/addusers.php and /admin/editadmins.php handlers accept account-creation fields, including level=SUPERUSER, without an anti-CSRF token. Exploitation requires an authenticated administrator's browser to submit the crafted form, after which the new account can administer the site.
