{"id":"CVE-2023-28114","aliases":["GHSA-6f27-3p6c-p5jc","GO-2023-1653"],"url":"https://o3.security/vulnerability/CVE-2023-28114","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.","published":"2023-03-22T18:30:16.774Z","modified":"2026-08-12T03:51:10.517950304Z","cvss":{"score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N"},"epss":{"score":0.00192,"percentile":0.0905,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/cilium/cilium-cli","fixedVersion":"0.13.2"}],"fix":{"url":"https://github.com/cilium/cilium-cli/commit/fb1427025764e1eebc4a7710d902c4f22cae2610","label":"cilium/cilium-cli@fb14270"},"references":[{"type":"WEB","url":"https://artifacthub.io/packages/helm/cilium/cilium"},{"type":"WEB","url":"https://github.com/cilium/cilium-cli/releases/tag/v0.13.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/28xxx/CVE-2023-28114.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/cilium/cilium-cli/commit/fb1427025764e1eebc4a7710d902c4f22cae2610"},{"type":"PACKAGE","url":"https://github.com/cilium/cilium-cli"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.517950304Z"}}
