The transmission bittorrent client uses a client/server architecture, the user interface is the client and a daemon runs in the background managing the downloading, seeding, etc.
Clients interact with the daemon using JSON RPC requests to a web server listening on port 9091. By default, the daemon will only accept requests from localhost.
A sample RPC session looks like this:
$ curl -H 'X-Transmission-Session-Id: foo' -sI '{}' http://localhost:9091/transmission/rpc
HTTP/1.1 409 Conflict
Server: Transmission
X-Transmission-Session-Id: JL641xTn2h53UsN6bVa0kJjRBLA6oX1Ayl06AJwuhHvSgE6H

$ curl -H 'X-Transmission-Session-Id: JL641xTn2h53UsN6bVa0kJjRBLA6oX1Ayl06AJwuhHvSgE6H' -d '{"method":"session-set","arguments":{"download-dir":"/home/user"}}' -si http://localhost:9091/transmission/rpc

As with all HTTP RPC schemes like this, any website can send requests to the daemon with XMLHttpRequest, but the theory is they will be ignored because requests must read and request a specific header, X-Transmission-Session-Id. Unfortunately, this design doesn't work because of an attack called "dns rebinding". Any website can simply create a dns name that they are authorized to communicate with, and then make it resolve to localhost.
The attack works like this:
- A user visits http://attacker.com.
- attacker.com has an
