Problem Name : BUTTONSProblem statement (250 points):
There is a website running at http://2018shell2.picoctf.com:18342 (link). Try to see if you can push their buttons.
Hints given :
What's different about the two buttons?
Solution:
As i opened the websit a button with tag Push me was there and after pressing the button another window with opened with a hyperlink named as button2 was there but it was not a button.On clicking that i was redirected to some other page with no flag.So using the hint i saw the source code of 2nd page and tried to changed that hyperlink to a button format.
The orignal code was :
<div>    You did it! Try the next button: Button2</div>
and i changed it this way using code of button 1 just change the link in button1 source to button2.php: <form action="button2.php" method="POST">    <input type="submit" value="PUSH ME! I am your only hope!"/></form> 
and after clicking the button i was awarded with flag :
Well done, your flag is: picoCTF{button_button_whose_got_the_button_25a99f84}
