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.
-----------
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

------------------------
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.
