Linux-only environments are not affected by it.**\n\nPlease 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.\n\n### Patches\n\nPatched versions include Rancher Manager `2.8.9` and `2.9.3`. For RKE2 Windows nodes, please refer to its [specific advisory](https://github.com/rancher/rke2/security/advisories/GHSA-x7xj-jvwp-97rv). No patches are available for 2.7, therefore users are urged to upgrade to newer minor versions or to apply the manual workaround below.\n\n\n### Workarounds\n\nUsers are advised to upgrade to a patched version of Rancher Manager. 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.\n\n\n### References\n\n- [CVE-2023-32197](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-32197)\n- [RKE2’s GHSA-x7xj-jvwp-97rv](https://github.com/rancher/rke2/security/advisories/GHSA-x7xj-jvwp-97rv)\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n- Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries.\n- Open an issue in the [Rancher](https://github.com/rancher/rancher/issues/new/choose) repository.\n- 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/).\n\n## Affected packages\n\n- `github.com/rancher/rancher >= 2.7.0, < 2.8.9`\n- `github.com/rancher/rancher >= 2.9.0, < 2.9.3`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/rancher/rancher 2.8.9`\n- `github.com/rancher/rancher 2.9.3`","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
