###############################################
Vuln. Description:
SunShop Shopping Cart contains a flaw that allows a remote cross site
scripting attack. This flaw exists because input passed to
"prevaction","previd","prevstart",
"itemid","id","action" 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.
examples:
/index.php?action=item&id=15&
prevaction=[XSS]
/index.php?action=item&id=15&
prevaction=category&previd=[XSS]
/index.php?action=item&id=15&
prevaction=category&previd=2&
prevstart=[XSS]
/index.php?action=sendtofriend&
type=item&itemid=[XSS]
/index.php?action=item&id=[XSS]
/index.php?action=[XSS]
###############################################
Solution:
Edit the source code to ensure that input is properly sanitised.
