Paypal is affected by an XSS vulnerability where it fails to validate input for the following url:
https://www.paypal.com/xclick/business= One can add arbitrary javascript with no need for any filter evasion. https://www.paypal.com/xclick/business=<script> alert("xss"); </script> As far as I know only the above url is affected. All of the usual XSS attacks will work with this. Cheers. _______________________________________________ Full-Disclosure - We believe in it.
