Now, perhaps some clever person could affect FMC instructions or nav aids, but no one is going to take control of a 737 or 757 in a manner that can't be immediately remedied by the flight crew.
I'd be a bit more worried if they were talking a FBW aircraft...
You're overlooking the fact that a good portion of flight time is under control of the autopilot and autothrottles, which are under the control of the FMS. IF someone could hack into the FMS or convince the pilots to execute a hacked ACARS or CPDLC clearance, he COULD effectively control the flight controls and throttles... HOWEVER, hacking into the FMS doesn't appear to be possible in the scenarios covered here...
