Ukrainian commercial CMS.

Abuse of Functionality (WASC-42):

http://site/users/register

At registration and password recovery pages it's possible to enumerate 
e-mails of the users (which are logins).

Insufficient Anti-automation (WASC-21):

Even captcha is using at these pages, it's not needed to enter correct 
captcha for enumeration of e-mails (logins) of the users.
