This runtime provides services such as security and garbage collection, and gives a common interface down to the hardware. NET languages are compiled to code that runs on the Common Language Interpreter (CLI), in what’s known as the Common Language Runtime (CLR). NET Framework provides a virtual environment designed to allow language interoperability. You’ll use libraries to abstract that from you (such as #include to get access to the printf function), but the resulting program interacts with the hardware. When you write a program in C or C++, and compile it, it interacts with the hardware through system calls. NET framework, but don’t have a great feel for what exactly that means. If you’re not a Windows developer or senior security expert, it’s likely that you’ve heard of the. I’m adding this to the Ethereal series of posts because I will show how to use COR Profiling to get a Meterpreter shell on Ethereal at the end of the post. This Applocker bypass is solid, and if it worked on Fighter (basis for the original Hack Player’s post) and Etherearl, it will likely prove valuable again. This post is the result playing around with what I learned watching IppSec’s post-Ethereal video and reading through the original source from Hack Players. I wanted to play with it myself, and get some notes down (in the form of this post). IppSec demoed a method to bypass those filters using COR Profiling. ![]() Things would have been a lot better if I could have just gotten a shell to connect back to me over one of the two open ports, but AppLocker made that nearly impossible. And each time I wanted to exploit some user action, I had to set my trap in place, kill my shell, start two listeners, and wait. On of the challenges in Ethereal was having to use a shell comprised of two OpenSSL connections over different ports. ![]()
