Basic Challenge 7
no, you won't see any visible changes…
step1: if (you have the web-developer toolbar (firefox extension)): (Go to the "Cookies" tab) && (select "View Cookie Information"); else: (Get web-developer toolbar) && (goto step1);
:P
then, do your injection, and view those cookies again…if you see a change, then it worked :)
Let's take a look to this challenge together… It says there is a cookie login script, so you surely want to check your cookies….there are two of them, a username and a password,but are decrypted and you need to encrypt them. So,when you submit, the login page will check your cookies and compare them to some encrypted data. If they are equal,you are athenthicated. So now you should understand what to do to pass the first login.
Then you have a second login which check you input on a SQL database. There are two ways to pass it. You should know the most basic SQL injection(if you don't, google for it),try it. Or you can guess the username, it won't be that hard, you know it.
Hope this helps
