Reset ISE CLI password

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

Re: Reset ISE CLI password

Hi,

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

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.

Re: Reset ISE CLI password

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

Re: Reset ISE CLI password

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?

Re: Reset ISE CLI password

Are you using putty?try using hyper terminal and see if the option displays correctly.

Reset ISE CLI password

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,

Hello Guys,

I have the same problem here, but my admin/monitoring note are Vmware machines.

Whats the procedure of VMware environment?

Tks.

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.

I think this problem can be solved just changing admin password policy settings via GUI and truying again.

Reset ISE CLI password

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!

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

http://www.cisco.com/en/US/docs/security/ise/1.1.1/installation_guide/ise_postins.html#wp1189908

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.

Reset ISE CLI password

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.

Hi,

I will do it after using the DVD to recover the admin password for the CLI. I know, it is quite annoying...

Very useful, thanks!

Re:Reset ISE CLI password

Hi,

We have two ISE boxes (ISE-3395-K9); one will be configured as Admin Primary Node and the second one as Admin Secondary Node. These boxes have the Basic Licence. Therefore, they will not support Profiling/NAC, ISEs will be only used for RADIUS Authentication to replace our Cisco ACS Servers.

There are different ISOs in the Cisco website (“Download Software”) so I am confused about which is the right ISO for my scenario. The two Cisco ISEs (ISE-3395-K9) will be configured as PAN Nodes, because Inline Posture Node (IPN) is not supported due to the Basic Licences that we have, so I guess that the ISO that I need to use is: “Cisco ISE Software Version 1.2.0 full installation(no IPN functionality).This ISO file can be used for installing ISE on ISE-33x5, NAC-33x5 Appliances, SNS-34x5 Servers and CSACS-1121 as well as a VM installation on VMWare ESX/ESXi 4.x/5.x

Is that right?

Thanks in advance!

Re:Reset ISE CLI password

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.

You sound like someone who work for Cisco.

Password locking is NOT the best practive.  The best practice is having IPS in-line in front of the ISE to detect this and block the attacker for the brute force password attack, not enable passwrod locking mechanism by default.  This is stupid by design.

The other things about password locking of the UI account.  That feature can NOT be turned off either.  How stupid can that be?  Cisco has recognized it and according to Cisco (I have not been able to confirm it), you can disable this feature in version 1.2

Cisco Employee

Yes, it can be disabled.ise12

Yes, it can be disabled.

ise12/admin(config-password-policy)# no password-lock-enabled ?
  <cr>  Carriage return

Have you deployed an IPS in front of ISE to looking for HTTP Posts specifically for username/password?  What if you had 5 different people logging into ISE at the same time and each mistyped the password. Would your signature fire?  What if it was just 1 person with 5 incorrect logins?

What if it's encrypted?

Are you going to look for the ISE reply message of " Invalid username or password" 5 times then fire the rule?

Reset ISE CLI password

Hello,

I am having the same issue; ISE 1.1.12, all 4 nodes are CLI-locked.

Thank you for the info to clear it, but I have this question:  Rather than disabling password-lockout, can I create a second CLI-capable account with a unique username?  Or will this "scanning" disable anything?

thank you,

Andrew

Reset ISE CLI password

You can create any amount of CLI accounts through the CLI. From global config

username password plain role admin

The 'scanning' that was previously mentioned on this thread could be the cause of accounts being locked out if the process involves attempting to brute force access into the box. It will only lock out the account that is being attempted, so if you have a second user that will be unaffected (unless the scanner rotates common usernames and attempts your second user).

Thanks Sam,

That's what I figured; if I created a random/unique username then I would have a reliable backdoor.

The customer doesn't want to disable the lockout or modify their network security scanning.

thanks,

Hi Tarik,We have the same

Hi Tarik,

We have the same problem. We're unable to login to both CLI and GUI.

In our setup, ISE is run in a single VM.

We followed the same procedure(http://www.cisco.com/en/US/docs/security/ise/1.1.1/installation_guide/ise_postins.html#wp1194396) to recover the password. When option 3 ([3] Reset Administrator Password (Keyboard/Monitor)) was selected after booting from DVD, the below error is thrown. Attached screen shot for your reference.

"Failed to find ADE-OS startup configuration, Unable to proceed with password recovery"

Please help.
