Tendenci CMS contains a flaw that allows a remote cross site scripting attack.  This flaw exists because the application does not validate "category","searchtext", "jobcategoryid, and "contactcompany" variables upon submission to the search.asp 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.
