I was flying about a year ago and was messing with the in flight entertainment in a 787. It was pretty easy to figure out how to get to a boot menu in the in flight entertainment. I was thinking "huh, this seems like maybe a way in". Seeing how the in-flight displays navigational data it must be on the network as the flight systems. I'm sure there is some kind of segregation but its probably not ultimately secure.
