[0x02] Bug: [Admin Password Disclosure]
|
|
######
|
|
|
|
Bugged file is: /[path]/config.inc
|
|
|
|
[CODE]
|
|
|
|
<?
|
|
$adpass="admin"; //change admin to your password of choice
|
|
?>
|
|
|
|
[/CODE]
|
|
|
|
Just going at this path you will get Administrator's password.
|
|
|
|
[!] FIX: Don't allow direct access to this file and change it's extension with .php
|
|
|
|
|
|
[!] EXPLOIT: /[path]/config.inc
|
|
$adpass="admin_pwd";
|

[0x03] Bug: [Permanent XSS]
|
|
######
|
|
|
|
Bugged file is: /[path]/uploadform.php
|
|
|
|
[CODE]
|
|
|
|
$fp =fopen($file, "w+");
|
|
$name=stripslashes($name);
|
|
$des=stripslashes($des);
|
|
$code=stripslashes($code);
|
|
$author=stripslashes($author);
|
|
$w ="name=".$name."&price=".$price."&code=".$code."&des=".$des."&author=".$author."&mail=".$mail."&date=".$date."&web=".$web;
|
|
|
|
[/CODE]
|
|
|
|
Once we got Administrator's password, we are able to log in.
|
|
|
|
Login at this path: /[path]/admin.php
|
|
|
|
Then just go at this path: /[path]/uploadform.php
|
|
|
|
Fill the forms, and put in description form the following code:
|
|
|
|
<script>alert("XSS")</script>
|
|
|
|
After this action, data that we typed in the upload form, will be saved on .txt files.
|
|
In index.php source code, we can see that the script opens the .txt files, and prints
|
|
it's values directly in html code.
|
|
|
|
|
|
[!] FIX: Filter variables before printing them in the html code.
|
|
preg_math the < > " chars. Filter illegal chars.
