There’s a server-side request forgery vulnerability in that part of the site, and I’ll use it to access a crypto service running on localhost. That key is enough for me to forge a cookie as admin and get access to additional places on the site. With that, I’ll leak one of the keys used by the application, and the fact that there are more protections in place. I’ll start by uploading a SHTML file that allows me to read the configuration file for the application. Perspective is all about exploiting a ASP.NET application in many different ways.
