Bug vulnerability class | Configuration |
Bug description | An attacker who is able to get a direct connection to the port can identify the banner of this web server as MS IIS. By this knowledge further enumerations and attacks are possible. |
Bug solution | A service if not needed should be de-installed or disabled. If this is not possible, an access control list (ACL) with firewalling should be applied to this port. And if possible change the welcome banner to confuse an attacker and give him false information. This can be done with IIS Banner Changer by Tiago Halm <thalm at netcabo dot pt> [http://www.kodeit.org/utils/iisbanner.zip]. |
