Fortinet Fortigate Firewall contains a flaw that allows a remote Cross Site Scripting attack. This flaw exists because the application does not validate "button" variables upon submission to the "selector" script. This could allow a user to send a specially crafted request that would execute arbitrary code on the server leading to a loss of integrity.
