[原文]Multiple cross-site scripting (XSS) vulnerabilities in Avactis Shopping Cart 0.1.2 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) category_id parameter in (a) store_special_offers.php and (b) store.php and (2) prod_id parameter in (c) product_info.php. NOTE: this issue might be resultant from SQL injection.
Avactis Shopping Cart contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'category_id' variable upon submission to the 'store_special_offer.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Upgrade to version 0.1.3 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
