SQL INJECTION (SQLi):

////////////////////////

<<<<---------++++++++++++++ Condition: magic_quotes_gpc=off +++++++++++++++++--------->>>>


-------
INTRO:
-------


An exploit was published by drosophila with Multiple SQL Injection in EZ-blog Beta-1, 
they've (apparently) fixed it but the system is still vulnerable.


Source: http://www.milw0rm.com/exploits/8128


-----------
FILE VULN:
-----------

Path --> [HOME_PATH]/public/specific.php

...

$whichcategory = Trim($_POST['category']);

...
 if ($whichcategory=='All'){
  $query  = "SELECT * FROM content ORDER BY id DESC"; 
 }else{
  $query  = "SELECT * FROM content WHERE  topic ='" . $whichcategory . "' ORDER BY id DESC";
 } 
 $result = mysql_query($query);
...


------------------
PROOF OF CONCEPT:
------------------

Copy and save --> PoC.html.
Configure --> HOST, HOME_PATH

<html>
<title>

</body>
</html>


------------------------
EXPLOIT (SHELL UPLOAD):
------------------------

This aplication hasn't admin authentication using DB, ie, admin panel uses .htaccess file. 
This is a complete exploit: SQL Injection --> Shell Upload, and XSS...all in one ;)

Copy and save --> exploit.html.
Configure --> HOST, HOME_PATH and COMPLETE-PATH.
