Cisco uses MD5 to encrypt the password so like every other encrypted password(UNIX, NT, etc) it is crackable. The trick is getting the encrypted string from your sh run config.Plug that into a cracker and it will eventual crack the password by doing the encryption algorithm with a dictionary attack against the encrypted string. If you have a good long random password with many mixed characters it will take much longer to crack but nonetheless will be crackable especially if you have a fast enough CPU.
If you do a search on google you fill find variuos tools. I'd rather not endorse any specifically but they have worked for me in the past when I forgot my password.
