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);
..

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.
