CVE-2020-21358Public exploitNetwork attack vector

User creation via forged administrator request

Published Aug 6, 2021 · Updated Aug 4, 2024

Cross-site request forgery in Wage-CMS 1.5.x-dev allows remote attackers to add users through an administrator's browser. The /admin/users employee-management flow accepts a forged form submission without a request-bound anti-CSRF check and processes it as the signed-in administrator. Exploitation requires an authenticated administrator to visit and submit a crafted HTML page, after which an employee account is created.
