| ------------------------------------------------------------------------------------------------ |
| The following script is used for displaying teamspeak information by users and allowing others   |
| to login to these servers and etc.                                                               |
|                                                                                                  |
| It's most commonly used by teamspeak hosting companys which makes it kinda bad that this exists. |
|                                                                                                  |

|                                             Vulnerability                                        |
| ------------------------------------------------------------------------------------------------ |
| Although the following script has multiple sql injections there is only one which we really...   |
| Found to be useful enough to include inside of the exploit code.                                 |
|                                                                                                  |
| So that is the only one that we will go into detail with below...                                |
|                                                                                                  |
| If we go to login.php and view the line 20                                                       |                                                                                                 |
| We see the following code...                                                                     |
|                                                                                                  |
| <?php                                                                                            |
|    $r = query("SELECT * FROM $dbtable1 WHERE server_id='$_GET[detail]'");                        |
| ?>                                                                                               |
|                                                                                                  |
| If you understand php you can see from this that the code is not properly sanatized before being.|
| Put into the query and executed... The way it is currently would allow a remote attacker to...   |
| Add on SQL in order to preform a sql injection.                                                  |
|                                                                                                  |

| ------------------------------------------------------------------------------------------------ |
| Take the code at login.php line 20 and make it the following...                                  |
|                                                                                                  |
| <?php                                                                                            |
| 	$userinput = mysql_real_escape_string($_GET[detail]);                                      |
| 	$r = query("SELECT * FROM $dbtable1 WHERE server_id='$userinput");                         |
| ?>                                                                                               |

| ------------------------------------------------------------------------------------------------ |
|   The vulnerability was discovered remotely by DeadlyData and Kap of TheDefaced Security Team    |
|   It was then looked at via source code and the script was fully audited to find it was more...  |
|   Vulnerable then we had thought in total there are about 5 un sanatized user based inputs.      |
|                                                                                                  |
|   Which may lead to more vulnerabilties such as other SQL injections or XSS flaws.               |
