Re: Enumerate Root Web Server Directory Vulnerability for IIS 4.0

All,

A way to stop these types of attacks when enumeration of a file path on an
IIS box occurs is to replace the errors with non-default errors pages.

Subject: Enumerate Root Web Server Directory Vulnerability for IIS 4.0

BugTraq,

   I was recently auditing the security on one of my web servers when I came
across a new Extension Enumerate Root Web Server Directory Vulnerability for
IIS 4.0. Going to the main website and asking for anything.idq I get the
page cannot be found. But if the files for the web server reside on a share
the full network path is found.

The Exploit:

On the shared network drive, http://server/anything.idq

The file \\share\wwwroot\inetpub\webpage\*.idq is on a network share. IDQ,
IDA and HTX files cannot be placed on a network share.

Tested on Windows NT 4.0 Service Pack 5 and 6a

I would like to say thank you to rain.forest.puppy. for all of his help.

props out to ADM, Wiretrip, w00w00 and l0pht.
