Reset ISE CLI password

Kashish_Patel — Mon, 11 Mar 2019 02:21:19 GMT

Hi Security Experts,

Is it possible to reset/recover ISE CLI password from ISE WebGUI? I am able to get into web gui of ISE, but not able to login to its CLI. So want to reset/recover ISE CLI password from its GUI.

PS: I rate useful posts.

Thanks,

Kashish

Hi,

You can only recover the cli password after rebooting the ise node from install DVD. There is no other method.

Hi Tarik,

Thanks for replying.

Here is what happened:

We have two admin ISE nodes (VMs) and two policy service nodes.

Everything (GUI and CLI) was fine for all the 4 nodes. I then changed the admin GUI password on primary admin ise node. I did NOT change password on any of the other three nodes. However, I can login to web gui of all the four nodes using the password that I changed. Is it because of the replication/sync amongst ise nodes?

Does the password sync happen only for web gui passwords and not for cli passwords? Will deregistering/registering the node help in getting its password back? I am positive that the password used to work before and problem happened only after I changed the web gui password of the admin node. I am not sure how the passwords are getting sync'd amongst different ise nodes.

Thanks,

Kashish

Yes that is correct, the admin credentials/polcies are stored in the application database which is shared amongst all the nodes in the deployment. However, the cli password and also the database passwords are kept local on each instance.

Deregistering and re-registering will not affect the cli credentials. I have also experienced issues with the PSN nodes changing randomly but I havent had a chance to open a TAC case on this, I just reboot the nodes against the iso and then set them again.

Thanks,

Tarik,

As per the CLI-admin password recovery procedure at

http://www.cisco.com/en/US/docs/security/ise/1.0/install_guide/ise10_postins.html#wp1179256

I have inserted DVD in the hardware appliance, but I don't see any prompt with these options:

"Welcome to Cisco Identity Services Engine - ISE 3355

To boot from hard disk press

Available boot options: "

I just see login prompt ( and of course, I cannot login because I don't know the password). I am using serial console connection to the appliance. Any idea on this?

Hi Tarik,

I had successfully reset CLI admin password last time. Now three days back, this issue again happened and had to reset password again using DVD. Do you know if it is an existing bug? What are the triggers for the bug? we already encountered this issue twice in nearly 3-4 months and want to know what triggers it.

Thanks,

Kashish

It's the same, except since it's virtualized you dont need a DVD. Use the .iso files that are available on cisco.com and mount that to the VMware CD drive. Reboot the VM and watch the console, the procedure is the same from there.

What version of ISE do you have?

I haven't heard of any bugs like this, but I have heard of some customers with environments where there is an automated network scanner that attempts to log into any device with ssh available. ISE will lock out an account that has multiple authentication attempts against it.

Hi,

I have the same issue. I cannot login to the CLI and I would like to reset the admin password.

We are using is a Cisco ISE appliance, do we need to use a DVD to reset the password or it is a different process? I have checked the original box and I have only found the Licence and Warranty CD but there is no DVD.

Do you know what I need to do next?

Thanks in advance!

Joana.

yes, you need a DVD to reset the ISE CLI admin username and password.

I've also created a doc to reset different credentials within ISE.

Please ignore my last post. That was for acs 5.x

In order to download ISE 1.x ISO DVD, you need to download the s/w from below listed link.

http://software.cisco.com/download/release.html?mdfid=283801620&flowid=26081&softwareid=283802505&release=1.2&relind=AVAILABLE&rellifecycle=&reltype=latest

If you have too many attempts from the CLI, it will lock out the CLI password and the only way to recover this DVD. This is especially when you have security scanning system scanning the ISE thus locking out the "admin" CLI account. Stupid Cisco.

The work around is:

nkiseu1/admin(config)# password-policy

nkiseu1/admin(config-password-policy)# no password-lock-enabled

nkiseu1/admin(config-password-policy)# end

nkiseu1/admin#

That will ensure the "admin" account will not lock out after excessive attempts.

Keep in mind that this is a security appliance so having a password locking mechanism is a best practice which prevents brute force attacks. As far as scanning devices they should be tuned and configured or use a different user account so this doesnt happen.
