SQL injection vulnerability in the actionMultipleAddProduct function in includes/classes/shopping_cart.php in Zen Cart 1.3.0 through 1.3.8a, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the products_id array parameter in a multiple_products_add_product action, a different vulnerability than CVE-2008-6985.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
