{"id":"GHSA-6f27-3p6c-p5jc","summary":"`cilium-cli` disables etcd authorization for clustermesh clusters","details":"### Impact\n\n`cilium-cli`, when used to configure cluster mesh functionality, can remove the enforcement of user permissions on the `etcd` store used to mirror local cluster information to remote clusters. \n\nDue to an incorrect mount point specification, the settings specified by the `initContainer` that configures `etcd` users and their permissions are overwritten when using `cilium-cli` to configure a cluster mesh. An attacker who has already gained access to a valid key and certificate for an `etcd` cluster compromised in this manner could then modify state in that `etcd` cluster.\n\n### Patches\n\nThis issue is patched in `cilium-cli` 0.13.2\n\nAll previous versions of `cilium-cli` are affected. Users who have set up cluster meshes using the Cilium Helm chart are not affected.\n\n### Workarounds\n\nUse Cilium's [Helm charts](https://artifacthub.io/packages/helm/cilium/cilium) to create your cluster instead.\n\n### Acknowledgements\n\nThe Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to Marco Iorio for investigating and fixing the issue.\n\n### For more information\nIf you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community/#slack).\n\nAs usual, if you think you found a related vulnerability, we strongly encourage you to report security vulnerabilities to our private security mailing list: [security@cilium.io](mailto:security@cilium.io) - first, before disclosing them in any public forums. This is a private mailing list where only members of the Cilium internal security team are subscribed to, and is treated as top priority.","aliases":["CVE-2023-28114","GO-2023-1653"],"modified":"2026-09-10T03:49:52.790409539Z","published":"2023-03-21T22:30:43Z","database_specific":{"github_reviewed_at":"2023-03-21T22:30:43Z","nvd_published_at":"2023-03-22T19:15:00Z","cwe_ids":["CWE-280"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/cilium/cilium-cli/security/advisories/GHSA-6f27-3p6c-p5jc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28114"},{"type":"WEB","url":"https://github.com/cilium/cilium-cli/commit/fb1427025764e1eebc4a7710d902c4f22cae2610"},{"type":"WEB","url":"https://artifacthub.io/packages/helm/cilium/cilium"},{"type":"PACKAGE","url":"https://github.com/cilium/cilium-cli"},{"type":"WEB","url":"https://github.com/cilium/cilium-cli/releases/tag/v0.13.2"}],"affected":[{"package":{"name":"github.com/cilium/cilium-cli","ecosystem":"Go","purl":"pkg:golang/github.com/cilium/cilium-cli"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.13.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/03/GHSA-6f27-3p6c-p5jc/GHSA-6f27-3p6c-p5jc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N"}]}
