Vuln. Description:

Pinnacle Cart contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "setbackurl" parameter in "index.php" isn't properly sanitised before being returned to the user.
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.

example:

/index.php?p=&address_id=&setbackurl=[XSS]


###############################################
Solution:
Edit the source code to ensure that input is properly sanitised.
