Cisco ASA 5505 problem resetting the enable password - how to bypass the security policy

Hello,

I am trying to access & control a Cisco ASA 5505 firewall via console access. The problem is that I do not have a working enable password and I need to reset it. I've checked the Cisco manual and other various posts online and these are the instructions I was going to use:

1.      Power cycle ASA
2.      As it boots keep pressing ESC so that the ronmon> prompt shows up
3.      Type confreg
4.      Type n for each item except for: “disable system configuration” (push y)
5.      Type “boot” -> prompt will then become “ciscoasa>”
6.      Type “enable” and leave password blank, push enter, now it will change to ciscoasa#
7.      Type “copy start run”
8.      Now type “config t”
9.      Type “enable password cisco” (this sets pw to cisco)
10.      Type “config-register 0x10011”
11.      Type “exit”
12.      Type “copy run start”
13.      Type “reload” to reboot

The problem is that on Step #2 when I try to interrupt the boot up sequence, I get the following error:

WARNING:  Password recovery and ROMMON command line access has been
disabled by your security policy.  Choosing YES below will cause ALL
configurations, passwords, images, and files systems to be erased.
ROMMON command line access will be re-enabled, and a new image must be
downloaded via ROMMON.

It sounds like at this point the only way to get past this will be a factory reset. This is problematic since I want to retrieve the current running config. This is a live firewall being used daily by a small company.

Any ideas what I should take as the next step? Does anyone know if Cisco has a way to get past this if we purchase a service contract for this ASA to get the support?

If you have no access to the CLI/ASDM then you cannot retrieve the configuration and you need to reset the unit and configure it from scratch.

Can you access the ASDM?

Before step 7 type
Show start
This will show you the startup-config, which is what it normally boots from. Step 7 will over write what is currently the running-config (the factory state) with the startup-config (that you don't know the pw for) which will put things back to normal, then the rest of the steps just update the enable password and then save it.  You should make a backup copy of the config using tftp or copy and paste into notepad one screen at a time (the whole config is probably too big for your clipboard) if you don't know how to tftp.

Henk: no I do not have access to the ASDM - I actually wanted to enable SSH/ASDM until realizing this client's old tech locked down CLI

Paranormastic: I don't get past step 2 as mentioned.

Then you have no other option than reset en rebuild from scratch. A good time to update the software ;-).

I am also 95% convinced that I have no option but to reset, but the goal of this post was to get the extra 5% that let me know there is absolutely nothing that can get past what I described (like a "magic" Cisco backdoor).

You can remove the flash from the ASA5505 (remove the screws), mount it in a reader/other ASA and see what is on it. maybe there is an old config.

I am closing this one - so far we are dealing with a legal battle with the old admin that locked down the ASAs... thanks for the input guys, looks like there is no way to reset that lock.

I'm only picking my own comment because just like I suspected there was no solution to this problem. The solution is there is way to get past the lock.

The solution is that there is no way without saving the config.. even if it is not a satisfying answer, it still the right answer.
