BosClassifieds Classified Ads System contains a flaw that allows a remote cross site scripting attack.  This flaw exists because the application does not validate the "returnTo" variable upon submission to the account.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.
