RKE2 allows privilege escalation in Windows nodes due to Insecure Access Control Lists
ImpactA vulnerability has been identified whereby RKE2 deployments in Windows nodes have weak Access Control Lists (ACL), allowing `BUILTIN\Users` or `NT AUTHORITY\Authenticated Users` to view or edit sensitive files which could lead to privilege escalation.The affected files include binaries, scripts, configuration and log files:**This vulnerability is exclusive to RKE2 in Windows environments. Linux environments are not affected by it.**Please consult the associated [MITRE ATT&CK - Technique - Exploitation for Privilege Escalation](https://attack.mitre.org/techniques/T1068/) for further information about this category of attack.PatchesPatched versions include RKE2 `1.31.0`, `1.30.2`, `1.29.6`, `1.28.11` and `1.27.15`.WorkaroundsUsers are advised to do a fresh install of their RKE2 Windows nodes using a patched RKE2 version. 
When that is not possible, users can enforce stricter ACLs for all sensitive files affected by this Security Advisory running [this](https://github.com/rancherlabs/support-tools/blob/master/windows-access-control-lists/README.md) PowerShell script as an Administrator on each node.References[CVE-2023-32197](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-32197)[Rancher Manager’s GHSA-7h8m-pvw3-5gh4](https://github.com/rancher/rancher/security/advisories/GHSA-7h8m-pvw3-5gh4)For more informationIf you have any questions or comments about this advisory:Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.Open an issue in the [Rancher](https://github.com/rancher/rancher/issues/new/choose) repository.Verify with our [support matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/).
