Açıklama

### Impact A 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: ``` C:\etc\rancher\node\password C:\var\lib\rancher\rke2\agent\logs\kubelet.log C:\var\lib\rancher\rke2\data\v1.**.**-rke2r*-windows-amd64-*\bin\* C:\var\lib\rancher\rke2\bin\* ``` **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. ### Patches Patched versions include RKE2 `1.31.0`, `1.30.2`, `1.29.6`, `1.28.11` and `1.27.15`. ### Workarounds Users 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 information If 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/).
