The FQDN must also not resolve to a reserved address (192/172/127/10). The server must also respond to a HEAD request for the payload, prior to getting a GET request. This exploit leverages an authenticated improper input validation in Wordpress plugin Popular Posts <= 5.3.2. The exploit chain is rather complicated. Authentication is required and 'gd' for PHP is required on the server. Then the Popular Post plugin is reconfigured to allow for an arbitrary URL for the post image in the widget. A post is made, then requests are sent to the post to make it more popular than the previous #1 by 5. Once the post hits the top 5, and after a 60sec (we wait 90) server cache refresh, the homepage widget is loaded which triggers the plugin to download the payload from our server. Our payload has a 'GIF' header, and a double extension ('.gif.php') allowing for arbitrary PHP code to be executed. }, 'License' => MSF_LICENSE, 'Author' => [ 'h00die', # msf module 'Simone Cristofaro', # edb 'Jerome Bruandet' # original analysis ], 'References' => [ [ 'EDB', '50129' ], [ 'URL', 'https://blog.nintechnet.com/improper-input-validation-fixed-in-wo
