Penetration Testing: Sgdynamo.exe Script -- Path Disclosure

["Ruso, Anthony" <aruso () positron qc ca>]

I contacted Microsoft and they had no idea.

Either way: 

Sgdynamo.exe is a script that sits in your cgi-bin/scripts directory. 

It expects a HTNAME identifier like so

Surprisingly enough if you throw it a bogus HTNAME identifier is discloses a
path to "I don't know where" but it's enough to tell you if it's a Microsoft
OS or Not.

Has anyone heard of this?

I've searched previous post for the file and didn't find anything at all. 
Any leads would be great !
