What's wrong with the packet I sent?

Despite what that error message says, you actually DO need to spoof your referrer to get your submission to work. so use:

curl_opt($yourvar, CURLOPT_REFERER, $yourdata)


and it should return the page.
If you know it, you know it. Public no longer.

Didn't try timed but I've got similar reply when trying the other
The site is checking if you are logged in
and if referer is from challenge page ( here .../timed2/index.php )

I don't think it's checking if I'm logged in: that's not very logical. If it was, it wouldn't give me a 'malformed request' error.

I'm not using curl. I'm writing the packet manually, then using sockets:

function makePacket($host, $page, $agent, $cookie, $data)
{
#Generate the packet
$packet = "POST ".$page." HTTP/1.1\r\n";
$packet .= "Host: ".$host."\r\n";
$packet .= "User-Agent: ".$agent."\r\n";
$packet .= "Content-type: application/x-www-form-urlencoded\r\n";
$packet .= "Content-length: 0\r\n"; /*strlen($data)*/
$packet .= "Set-Cookie: ".$cookie."\r\n";
$packet .= "\r\n";
$packet .= $data;

#return packet
return $packet;
}


Sure enough, it's the referrer! That's rather odd, I suppose it has to do with the POST attribute. This packet works just fine:


POST /index.php HTTP/1.1
Host: www.hellboundhackers.org
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0b; Windows NT 6.0)
Referer: http://hellboundhackers.org/forum/viewthread.php
Content-type: application/x-www-form-urlencoded
Content-length: 0
Set-Cookie: REMOVED

Well, yes you have to login in to access
http://www.hellboundhackers.org/challenges/timed/index.php
but you can access subdirectories without being logged
for referer I use Modify Headers in Firefox

Seeing as my PHP scblockedript is crafting the packet and not firefox, I doubt a firefox addon would be much help.

And, obviously you have to be logged in. That's why I set to cookie in the packets. I just didn't add the atual cookie there for obvious reasons.

For timed 2, as an example :
$header = array();
$header[] = "REFRER: http://hellboundhackers.org/challenges/timed/timed2/index.php";
$header[] = "Cookie: <yourcookiehere>";
ect...etc...
//rest of code
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
//That'd be better than defining the referer in cURL.

Once again, I don't need and won't use cURL. It doesn't give me the control over my packet content that I want. I'm drafting the packets myself. And, my connection is fine, I'm requesting pages fine, now I just need to write the regex code to finish the challenge, and I'm damned lazy and have a report to finish up today.
