GeniXCMS 1.1.7 is vulnerable to user privilege escalation due to broken access control. This issue exists because of an incomplete fix for CVE-2015-2680, in which "token" is used as a CSRF protection mechanism, but without validation that "token" is associated with an administrative user.

Cross-site request forgery (CSRF) vulnerability in MetalGenix GeniXCMS before 0.0.2 allows remote attackers to hijack the authentication of administrators for requests that add an administrator account via a request in the users page to gxadmin/index.php.
