James Bercegay has reported some vulnerabilities in osCommerce, which can be exploited by malicious people to disclose certain sensitive information, or to conduct cross-site scripting and SQL injection attacks.

1) Input passed to the "products_id" and "pid" parameters in "index.php" and the "goto" parameter in "banner.php" is not properly sanitised. This can be exploited to inject malicious characters into HTTP headers and may allow execution of arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities have been reported in version 2.2 and prior.

2) Input passed to unspecified parameters is not properly sanitised before being used to handle cache files. This can potentially be exploited to enumerate the existence of files on the system or to determine writable directories.

3) Input passed to session data via the "products_id" parameter when adding a product to the shopping cart is not properly sanitised before it is used in a SQL query in shopping_cart.php. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been reported in version 2.2 Milestone 2 prior to Update 060817.

Solution
Update to version 2.2 Milestone 2 Update 060817.
