# Exploit Title: Simple PHP Blog 0.8.4 - Cross-Site Request Forgery (Add
Admin)
# Author: Besim
# Google Dork: -
# Date: 07/10/2016
# Type: webapps
# Platform : PHP
# Vendor Homepage: http://simpleblogphp.com/
# Software Link: https://sourceforge.net/projects/sphpblog/
# Version: 0.8.4
# Tested on: Ubuntu 14.04.5
Simple PHP Blog 0.8.4 versions 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/simple/manage_users.php?action=update&type=new
<http://localhost/simple/manage_users.php?action=update&type=new>*) that
will add a new user as administrator.
Once exploited, the attacker can login to the admin panel
(*http://localhost/simple/login.php <http://localhost/simple/login.php>*)
using the username and the password he posted in the form.
*CSRF PoC Code*
