Pick an Input validation issue (e.g. SQL injection, Cross Site Scripting ...) from chapter 4 and display at least two test scripts that you could run to test for the existence of the vulnerability.

Describe the test script and be sure to mention what the test results would be if you discovered a vulnerability and how you would fix it.

Note: This will take some additional research and perhaps even some small development to demonstrate your script works. So keep it simple where possible.
