Cracking Cisco login using custom wordlist

In this recipe we will see how we to gain access to Cisco devices, we will be using tools available in Kali. We will be using a tool called as CAT to perform the activity. CAT stands for Cisco audit tool. It is a Perl script which scans Cisco for common vulnerabilities.

Getting ready

For this exercise we have setup a device with a password to demonstrate the activity. We do not require any external tools as everything is available in Kali itself.

How to do it...

1. We have set up a Cisco router on 192.168.1.88. As mentioned we will use CAT:

2. We have used a custom wordlist for username and password, which contain the following details:

3. Once you are on the Metasploit console, enter the following commands:

      CAT -h 192.168.1.88 -w /root/Desktop/cisco_users  -a 
      /root/Desktop/cisco_pass 

The output will be as shown in the following screenshot:

4. As you can see, it the service to check for credentials and fetches with the valid password if it...
