How to recover the lost or forgotten password of Cisco PIX Firewall?

 

 

Today tip will help you to explain the password recovery methods for the Cisco PIX firewall. You can use these steps to recover password for different Cisco PIX Firewalls (for example 501, 506, 506E, 515E, 515, 525 and 535).

Follow the step-by-step procedure to recover the lost Cisco PIX Firewall: 

First make sure, you have connected your PC to the Ethernet and Console port of PIX Firewall using any emulation software.

Now turn the power switch off and back on to recycle the power then press Break or Esc key to. The monitor> prompt is displayed.

monitor>

Now use the interface command to specify the interface of PIX Firewall use for traffic.

monitor>interface 1

0: i8255X @ PCI(bus:0 dev:13 irq:11)

1: i8255X @ PCI(bus:0 dev:14 irq:8 )

Now use the address command to assign the IP address of PIX Firewall interface.

monitor>address 10.1.1.1

address 10.1.1.1

Issue the server command to assign the IP address of TFTP server for password recovery.

monitor>server 131.200.1.1

server 131.200.1.1

Issue the gateway command to specify the gateway address through which the server is accessible.

monitor>gateway 10.1.1.5

gateway 10.1.1.5

Now issue the file command to identify the file name to recover the PIX firewall password, for example np62.bin (download this file from Cisco website).

Now use the tftp command to start the password recovery process of the PIX Firewall, and then following message will appear.

tftp np62.bin@131.200.1.1 via 10.1.1.5....................................................
