2DescriptionGitHub Advisory
The Icinga PowerShell Framework provides configuration and check possibilities to ensure integration and monitoring of Windows environments. In versions prior to 1.13.4, 1.12.4, and 1.11.2, permissions of the Icinga for Windows certificate directory grant every user read access, which results in the exposure of private key of the Icinga certificate for the given host. All installations are affected. Versions 1.13.4, 1.12.4, and 1.11.2 contains a patch. Please note that upgrading to a fixed version of Icinga for Windows will also automatically fix a similar issue present in Icinga 2, CVE-2026-24413. As a workaround, the permissions can be restricted manually by updating the ACL for the given folder C:\Program Files\WindowsPowerShell\modules\icinga-powershell-framework\certificate (and C:\ProgramData\icinga2\var to fix the issue for the Icinga 2 agent 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 PowerShell Framework versions prior to 1.13.4, 1.12.4, and 1.11.2 expose private certificate keys due to overly permissive directory permissions that allow all local users read access to the certificate folder. A local attacker with user-level privileges can retrieve these private keys to impersonate the Icinga service or intercept monitoring communications. No patch is currently available; manual ACL restrictions on the certificate directory are required as a temporary mitigation.
