DescriptionGitHub Advisory

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.

AnalysisAI

Icinga 2 on Windows versions 2.3.0 through 2.15.1 fail to properly restrict file permissions on the %ProgramData%\icinga2\var directory, allowing any local user to read sensitive data including private keys and synchronized configurations. All Windows installations are affected, and attackers with local access can extract cryptographic material and configuration details for lateral movement or further compromise. Patches are available in versions 2.13.14, 2.14.8, and 2.15.2, with workarounds available through updated Icinga for Windows packages or manual ACL remediation.
