Subject: samples from IIS allows creation of any file
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
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 :)
