AmnPardaz Security Research Team have discovered some vulnerabilities in cpCommerce, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks, and to disclose sensitive information.

1) Input passed to the "year" parameter in calendar.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Input passed to the "id_product", "id_manufacturer", and "id_category" parameters in index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "language" parameter in index.php and "action" in category.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources.

Successful exploitation of the category.php vulnerability requires that "magic_quotes_gpc" is disabled.

The vulnerabilities are confirmed in version 1.1.0 with the CPCchanges patch applied. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised and verified.
