Release Date:

MobileIron Critical Vulnerability



  • 16/12/2021 --- v1.0 -- Initial publication
  • 17/01/2022 --- v1.0 -- Edit the affected versions section for MobileIron Sentry


On December 15th, Ivanti updated its advisory related to CVE-2021-44228 vulnerability affecting MobileIron products [2]. While this CVE affects the Java logging library log4j [1], all products using this library are vulnerable to Unauthenticated Remote Code Execution.

Technical Details

The vulnerability exists in the Java logging library log4j. An unauthenticated remote attacker might exploit this vulnerability by sending specially crafted content to the application to execute malicious code on the server [1].

Affected products

  • MobileIron Core (All Versions)
  • MobileIron Sentry 9.13 and 9.14
  • MobileIron Core Connector (All Versions)
  • MobileIron Core RDB (All Versions)


Ivanti provided guidance to mitigate the vulnerably on its various affected products:

  1. Connect to the server CLI via SSH protocol;
  2. Use the command enable to elevate privileges;
  3. Install the workaround using one of the following commands (depending on the product you are updating):
install rpm url # MobileIron Core
install rpm url # MobileIron Sentry
install rpm url # MobileIron Core Connector
install rpm url  # MobileIron Core RDB
  1. Accept the service restart (y).


  • If FIPS mode is enabled on the server, then the effects of the installation will not persist across reboots. This means the RPM installation will need to be re-performed immediately after the system comes back up after a reboot.
  • If the server is upgraded, then the RPM installation will need to be re-performed, unless the version being upgraded to has a fix to the issue.
  • For Sentry, the RPM installation is applicable only to Sentry 9.13 and above. Versions prior to that are not vulnerable.
