How did you solve it?
I used JavaScript, but I still had to hurry up

javascript:alert((document.getElementsByTagName("b")[0].innerHTML).replace(/<span.*?n>/g,""));

I made a quick 'n dirty windows app where I pasted the original text and it would reproduce it properly on a second textbox.
And still barely made it

I somehow overkilled by using a quick and dirty Ruby script: https://gist.github.com/53796811c0db50a1bb27
Would have been much simpler if you weren't required to include the cookie from the original challenge page..

I copied to Notepad, which was prepared for delete "FOO", my left hand jumping from C to V and back

Took 3 or 4 tries.

But my pride says I should have used a script or so..

I used JavaScript as well, directly via FireBug:

Code: Select all

var getText = document.getElementsByTagName("b");
for (var i = 0; i<getText.length; i++){
    var getText2 = getText[i].getElementsByTagName("span");
    for (var j = 0; j<getText2.length; j++){
        getText2[j].innerHTML = "";
    }
}

worked like a charm.

Using the jquery-injector extension for Chrome, you can just do

Code: Select all

$('input[name="answer"]').val($('b').text().replace(/FOO/g, '')); $('form').submit()

in the console.

var element1 = document.createElement("script");
element1.src = "http://ajax.googleapis.com/ajax/libs/jq ... ery.min.js";
element1.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(element1);

jQuery('span').remove();
var myCtext=jQuery("b:last").html();
jQuery('input[name="answer"]').val(myCtext);
jQuery('input[type="submit"]').click();

I added <span> to bad tags in AdBlock

I used burp as a proxy and added a rule to delete all the s from HTTP-responses.
Then it was just fire and forget. Nice challenge!

I just used the console and a bit of JavaScript

Code: Select all

document.getElementsByName("answer")[0].setAttribute("value", document.getElementsByTagName("b")[0].textContent.replace(/FOO/g, ""));

This immediately just removes all "FOO"'s and inserts the result in the answer box.

I manipulated the clipboard in endless loop too remove 'FOO'. After start of the groovy script I did copy and paste in browser.

Code: Select all

import java.awt.datatransfer.StringSelection
import java.awt.Toolkit
import java.awt.datatransfer.*

String currentContent = ''
while (currentContent != 'stop') {
    sleep(100)
    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard()
    currentContent = clipboard.getContents().getTransferData(DataFlavor.stringFlavor)
    if(currentContent.contains('FOO')) {
        currentContent = currentContent.replaceAll('FOO', '')
        clipboard.setContents(new StringSelection(currentContent), null)
    }
}
println 'end'
