"default.ida" is the file that is requested on your web server. So in your
apache logs, you would see something like:

65.201.146.103 - - [19/Jul/2001:17:58:49 -0400] "GET
/default.ida?NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

HTTP/1.0" 400 323 "-" "-"

So in your httpd.conf or in your .htaccess file, you could add what I wrote
below to redirect requests to default.ida to something else.
Again, I don't know if this exploit honors HTTP redirects, and I haven't cared
enough to try and find out.
