Root CUCM, Unity Connection and UCCX 12.x and later

I am sure you must have read my old post about rooting CUCM, Unity Connection and UCCX. In case if you have not, please follow the article here. This rooting was applicable till 11.x version but from 12.x there is a little hardening. All the process remains same, there is a slight change this time which is mentioned in the below post.

Note: UC Collabing does not recommend to try and apply it on your production server and will not be held for any damages that could occur to your system. In case you perform this on your production servers, you may void Cisco contract. Rooting the Appliance may be illegal and we are not directly/indirectly responsible for this. This is only for lab and learning purpose!

The following process remains same as mentioned in our previous article – You may follow the article link as given here.

  • Pre-requisites for Rooting UC Application:
  • Loading CentOS ISO Image on Vmware:
  • Changing the BIOS Boot Order:

CUCM, Cisco Unity Connection, UCCX Root Access

Once you are done till above step, let’s make progress here: Once you save the changes, let the VM boot using CD/DVD.

  1. You will be prompted with CentOS Boot Screen Menu.
  2. Click on “Rescue Installed
  3. Choose a language and click on
  4. Choose Keyboard Type and click on
  5. Setup Networking – Click on
  6. Click on Read
  7. Click on
  8. Select Shell and Hit
  9. Enter the following command:chroot /mnt/sysimage/
    mount -o remount,rw /    >> This is the new command which needs to run for 12x devices
    passwd root       >> Create a Root Password and retype the same
    rm /etc/securetty
  10. Now you can follow back the old article as given above in the link starting from point number 19 till point number 20 and you are done. That’s it!See below 🙂uccollabing.comHappy Collabing!

    It’s very interesting to learn that you can do this. What would be the practical use for doing it, though? I’d highlight what you mentioned, though, that doing this will void any support from Cisco, so don’t do this to a production server.
