The type 5 passwords are protected by MD5 and as far as I know there is not any way to break them.

Depending on what type of password it is, you can probably use the password recovery procedure and replace the password with a new password. But I do not think that you can break the existing password.

level 5 passwords can't be broken.

level 7 passwords are easily broken.

actually all passwords can be broken :0)

If you know how to reverse an MD-5 string...

You can attack MD-5 with many programs on the net, you will need to brute force them, so the longer and more complex your enable secret the better... check this...

Cisco actually offering another type of password, knowing md-5 / type5's are vulnerable.

I've written both type 7 and type 5 password crackers in javascript that can run in your web browser (Google Chrome is faster on type 5 at the moment). Type 5 is a bit of a challenge in javascript unless the password is particularly weak.
