Hack This Site Javascript mission 1

Idiot Test

faith is learning Javascript, the only thing that is protecting her from hackers is luck. 
REQUIREMENT
=============
Before we go into the javascript mission , you should know the basics of javascript..atleast you should be able to understand the code written in JavaScript!
YOU CAN LEARN BASICS OF JAVASCRIPT FROM: w3schools  or SoloLearn
ON OUR MISSION
===========
This mission has a password field in it and a submit button "check password". But,as always we do not have the password.As usual we type in something and click the button to check its response. It says "Fail D:"
now, even i tried with empty password and it still says same message.
But, there is something different here than in basic levels,the message is shown in alert box, which means java-script is clearing in action behind this.Lets view its source code.Right click and select view page source.Now, here you have two option for finding the script in use, first is press "ctrl+f" and find box will appear and in it type <script>..but you will find more than one of these tags and should identify the right one.second method is the best one,as you know when we type wrong password, alert message is 'Fail D:' so in our find box we type the same and search.
Now you are in the right script!

function check(x)
{
if (x == "cookies")
{
alert("win!");
window.location += "?lvl_password="+x;
} else {
alert("Fail D:");
}
}
If you have the basic you can clearly understand from this code.Its checking if the password is equal to something and if its true it alerts 'win!', else 'fail D:'.
OUR PASSWORD IS

Password

Hack This Site Basic 8

Sam remains confident that an obscured password file is still the best idea, but he screwed up with the calendar program. Sam has saved the unencrypted password file in /var/www/hackthissite.org/html/missions/basic/8/  However, Sam's young daughter Stephanie has just learned to program in PHP. She's talented for her age, but she knows nothing about security. She recently learned about saving files, and she wrote a script to demonstrate her ability. So, we know the password is stored in some obscured password file.  Lets try the same code as we did in level 7. But the code 'ls' is not treated as command. so lets try it differently. Try with aaa;<!--ls--> it also failed but got a message: If you are trying to use server side includes to solve the challenge, you are on the right track: but I have limited the commands allowed to ones relevant towards finding the password file for security reasons(because there will always be that one person who decides to ...

Hack This Site Basic 10

Please enter a password to gain access to level 10 Only this much is written as hint.What we should do? I have tried reading the source code and there is no hint how the password is validated.So,we have no other way than intercepting the data.Once we enter the password and hit submit the password along with some request is sent to the server by the browser.There can be very vital information in this request.What we do is intercept this request before it is sent to the server.For this we use "Burp Suit" or some extensions for tampering data.For chrome and firefox,we have tamper data addon.Iam using chrome add on:  Tamper Chrome HOW TO USE IT? *Right click somewhere and select inspect. *Now select the three arrows pointing right on top right corner. *Now select  Tamper from it(make sure you have added the extension in             chrome). *Now input some password in out mission or leave it empty and hit submit. ...
