SSH exploit

Hello !
I am a studen in computer science (first year) and we have to acess a ssh server, we have a username and password, and we msut execute a file from another user (lets say i am user1@machine.com and i must copy the file "FILE" from the user "root")
The problem is the file "FILE" is protected from reading (or writing or executing) so do anyone have any idea ?

su dosent work, i dont have the password
and here are the environement variables:


user@pH ~ $ env
TERM=xterm
SHELL=/bin/bash
SSH_CLIENT=70.26.244.7 54742 1337
SSH_TTY=/dev/pts/3
USER=user
MAIL=/var/mail/user
PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
PWD=/home/user
