RE: previledge password in cisco routers

The only way to get it remotely is to get hold of and compromise a machine
on the network where the routers/switches resides. Then run a sniffer app
for just telnet and capture the individual keystrokes when someone logs into
the router and then enters the enable password. Remember inside the network
most telnet support functions to routers and switches are not encrypted so
by capturing a support personnel's telnet session will give you the enable
password. This can be done with SNMP also but that is another discussion.
The trick is to get the compromised machine to run the sniffer like tcpdump
etc.. Even if tacacs is used you will still see the open unencrypted telnet
keystrokes from the admin to the router. The router will then encrypt that
info and send it to the tacacs server for its backend process. You need to
just watch the admin's. steps. That is how you can get it remotely... Unless
the routers are configured for ssh for telnet you can see everything in the
clear with a sniffer..

Regards..

Do you seriously think there is a easy way to get the enable password
remotely? If you have the config, you can get it from there..if you have the
box you can do a password recovery by booting in rommon...otherwise the box
isn't yours..and you won't find a clear exact answer because there isn't
one.
