This is the way it's supposed to work. Since that other user owns /dev/ttyp3 he could "chmod 666 /dev/ttyp3" but this is very dangerous.
Some terminals have an escape sequence that will cause them to transmit the current line just as if it had been typed. On those terminals, you could send a command, then send cursor motion commands, and finally send that transmit escape sequence. This means that anyone on the system can execute any command as that user.
