"Default web page" vulnerability : false positives?

Question asked by Eric Vautier on Nov 25, 2011

"Default web page" vulnerability is useful to detect unused Web server that are active on a server. Very often, stopping the Web server solves a lot of other vulnerabilities, related to the (useless) Web site.


But very often, there's a necessary Web site, running properly, whose "default web page" is either a redirection or an authentication page (see examples below). These are false positives.


We have quite a number of these, it's very very long to mark each one of them as alse positives. Is there a workaround?


Many thanks in advance
