this after and the problem are the same *** WARNING **** Even if you have no .htw files on your system you're probably still vulnerable! A quick test to show if you are vulnerable: go to http://YOUR_WEB_SERVER_ADDRESS_HERE/nosuchfile.htw If you receive a message stating the "format of the QUERY_STRING is invalid" you _are_ vulnerable.This test is to see if you're vulnerable _before_ you apply the patch. After you install the patch you _will_ still get the same message....so what indicates that you *are not* vulnerable?
We'll - fairly long winded approach - therefore not a quick test: create a file call test.txt and put it on the root of the drive where your virtual root is found. If one doesn't already exist create a static file - eg default.html and place it in the root virtual directory. Try to access test.txt by using one of the exploits now floating around. If you manage it - then you're vulnerable s apply the patch. If you don't then you're not and the patch is already installed or .htw is not linked to webhits.dll Cheers, David Litchfield http://www.cerberus-infosec.co.uk/
