The primary mitigation is to upgrade Icinga 2 on Windows to versions 2.13.14, 2.14.8, or 2.15.2 or later, which include fixes for the ACL misconfiguration. For organizations unable to upgrade immediately, upgrading the Icinga for Windows agent to v1.13.4, v1.12.4, or v1.11.2 will automatically correct the ACLs for the agent components. Alternatively, administrators should manually audit and correct the ACLs on the %ProgramData%\icinga2\var directory and the C:\Program Files\WindowsPowerShell\modules\icinga-powershell-framework\certificate folder. This involves restricting read and write permissions to only the Icinga service user and system administrators, removing access for general local users. Regularly verifying ACL integrity and monitoring access logs for unusual local file access attempts can help detect exploitation attempts. Additionally, implementing strict local user account management and minimizing the number of users with local access to monitoring servers reduces risk. Organizations should also review and harden Windows host security policies and consider endpoint detection solutions to monitor for suspicious activity related to Icinga files.
Description
Icinga 2 is an open source monitoring system. Starting in version 2.3.0 and prior to versions 2.13.14, 2.14.8, and 2.15.2, the Icinga 2 MSI did not set appropriate permissions for the `%ProgramData%\icinga2\var` folder on Windows. This resulted in the its contents - including the private key of the user and synced configuration - being readable by all local users. All installations on Windows are affected. Versions 2.13.14, 2.14.8, and 2.15.2 contains a fix. There are two possibilities to work around the issue without upgrading Icinga 2. Upgrade Icinga for Windows to at least version v1.13.4, v1.12.4, or v1.11.2. These version will automatically fix the ACLs for the Icinga 2 agent as well. Alternatively, manually update the ACL for the given folder `C:\ProgramData\icinga2\var` (and `C:\Program Files\WindowsPowerShell\modules\icinga-powershell-framework\certificate` to fix the issue for the Icinga for Windows as well) including every sub-folder and item to restrict access for general users, only allowing the Icinga service user and administrators access.
