[S.H.Kang]

Hi everyone

Any have a Cisco Router password decryption tool or url.

enable secret level 5 not 7 !

I really need it ..

thanks.

no. There is no such tool for enable secret passwords. They are a
one-way MD5 hash. Other than brute force, I am not aware of any
attacks that are useable.

I don't believe one exists. Somebody please correct me if I'm wrong.
You're best bet is to use Cisco's password recovery procedure.

Used it - it worked :-)

Thats why I said 'enable secret' Regular enable passwords are easily
reverse engineered.

Yup,

GetPass does level 7 only. Not level 5!

Unfortunately, it is impossible to reverse level 5 passwords. They are
hashed by MD5 algorythm and can be recovered by brute force only. You
can recover only level 7 passwords. :(( You can use this tool for it:
http://www.winagents.com/products_cprt.htm

The single solution is to erase config in NVRAM and create it from
scratch. Also, if your router is configured to support SNMP
management, you can work with router's configuration using SNMP. Look
at www.winagents.com, their have tools to edit router configuration
through SNMP.

Check out http://packetstormsecurity.nl/cisco/ Go down to the bottam
of the page and there is a command line tool called Tomas that will
work with type 5 passwords.

You need to have the md5 hash though. With a five character password
without numbers or special characters you can do a brute force attack
and get the password in a couple hours on a decent machine. If the
password is quite long or uses number and special characters you could
be waiting a long time.

Try for yourself...
