Cross-site request forgery (CSRF) vulnerability in admin/manager_users.class.php in SantaFox 2.02, and possibly earlier, allows remote attackers to hijack the authentication of administrators for requests, as demonstrated by adding administrative users via the save_admin action to admin/index.php.
Cross-Site Request Forgery The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
