Anyone still running telnet on a Cisco router doesn't deserve to be managing one.

Cameron' Cc: full-disclosure () lists netsys com Subject: RE: [Full-disclosure] 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..

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.
