Build A Niche Store (BANS) 3.0 contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the "q" variable upon submission to the "search" 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.
