Smart Classified / Photo ADS contains a flaw that allows a remote cross site scripting attack.  This flaw exists because the application does not validate the "AdNum" and "Department" variables upon submission to the view.cgi 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.
