RE: SQL INJECTION (SHELL UPLOAD)--EZ-blog Beta2-->

This shell upload hack assumes the mySQL account running the E-Z-Blog has file 
create capabilities. If an admin does NOT tweak the running account and allows 
for this privilege then they are pretty much asking for it, wouldn't you agree?

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


An exploit was published by drosophila with Multiple SQL Injection in EZ-blog 
Beta-1, 
they (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);
..

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.
