Inter-Protocol Communication

Interprotocol communication involves creating a communication channel between two different protocols. Why do we care?

Wade Alcorn released a paper recently where he demonstrates exploiting a “contrived program… using JavaScript [encapsulating the] exploit within an HTTP request.”

I find this idea absolutely mind blowing, even though exploitation of multi-layered or more complex protocols may be alot more difficult. Can you imagine a network propogating worm using XSS and a shellcode payload encapsulated in an HTTP request.

We first saw port scanning and CSRF exploitation from the browser. Now the possibility of inter-protocol exploitation over HTTP. Nice work Wade.
