Well, with CHAP if you sniff the whole challenge you could run a
bruteforce program to try and crack the password. And also - if you
don't use encryption for the tunnel e.g. MPPE if you do an ARP attack
you could sniff the pppoe frames and see the traffic in it. I'm not sure
about it, though. But common logic suggests that.
