Avactis Shopping Cart contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'step_id' and 'CHECKOUT_CZ_BLOWFISH_KEY' variables upon submission to the 'checkout.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.
