Remy has already patched the HTTP Connector for this one (both Tomcat 4&5). I believe that the patch still needs to be ported to the JK2 Connector.

What can you get from this "exploit"? All I see is tomcat returning a 404 (not found) response with the javascript specified in the GET request, but javascript is executed on the client anyhow, so who cares? - What would the fix be? Not include the requested URL in the default 404 response page?
