Dimofinf 3.0.0 SQL Injection

Posted on 25 November 2015

# Dimofinf CMS Automatic Cookie SQL Injection exploit
# Google Dork: intext:"Powered by Dimofinf"
# Date: 19/11/2015
# Author: D35m0nd142
# Software link: http://www.dimofinf.net
# Version: 3.0.0
# Tested on: Dimofinf version 3.0.0
# Sometimes it happens that the vulnerability allow you to get moderators' username and password but not the list of tables and columns
# or viceversa; So if one of them does not work, you could try the other one anyway.
