Cross Site Scripting like any security risk can be mitigated (once we realize the risks to look for infections ( and/or identify the abberant sites or behavior that incurred contagion [for XSS Tunnels]). XSS allows us to inject HTML, iFrame, javascript, or a redirect into a website, where content checking is insufficient.  Many versions of Apache httpd are vulnerable to XSS and there are many types of XSS tricks.
