NT Using ASP And FSO To Read Server Files Vulnerability

The File System Object (FSO) may be called from an Active Server Page (ASP) to display files that exist outside of the web server's root directory. FSO allows calls to be made utilizing "../" to exit the local directory path.

An example of this syntax would be: http://www.server.foo/showfile.asp?file=../../global.asa

This vulnerability could be used to view the source code of ASP files or stream data into other ASP files on the web server.
