Re: IIS still revealing paths for web directories

Hello,

        There's another glitch when you have a password protected
webdirectory with IIS5 and sendin the http://www.iisServer.blah/blah.ida
When the root folder on that website is password protected you do not get
asked to authenticate but you just recieve the error like other
postings.  Ditto with guessing content of that folder the server would not
ask for the auth but just report a missing .ida file with full path of the
local file.

        IIS should ask for the password before giving out anything else.

BTW, different error messages are given depending on whether or not the path
up to the idq file exists.  In my brief testing:

http://www.example.com/exists/bah.ida
yields
The IDQ file C:\Inetpub\wwwroot\exists\bah.ida could not be found.


http://www.example.com/doesntexist/bah.ida
yields
File C:\Inetpub\wwwroot\doesntexist\bah.ida. The system cannot find the path
specified.

The same problem still exists on IIS4 (tested with SP5 -
didn't try on
SP6).

Still exists as far back as IIS3 also. (SP6a)

Can't reproduce the problem with IIS3 and SP6.

BTW: I'm running IIS3 on several servers without problems. I did not
want to upgrade to IIS4 due to the complexity of its internal
processes (and all those exploits that followed). My main complaint
is still that I do not want to run IIS under the system account as
IIS4 requires.

Anyway, a time will come when we need to upgrade to W2K and IIS5.
Does anyone have a comparison or analysis of IIS5 in respect to
security (data channels, posting acceptors, etc)?

Regards,
Frank
