Don

When teaching CEH, I use Windows 2000 Server Professional unpatched on VMWare. This will provide you a nice MSSQL platform to hack. If you have the CEHv4 materials, you should also have the databases to setup JuggyBank, a lab used in SQL Injection.

MYSQL, I'm afraid you are on your own.

Hope this helps.

SQL injection is performed through badly written scripts which allow you to enter SQL commands into its queries (i.e. they don't sanitise inputs). So you'll probably be safe with default setups of mssql and mysql.
