{"id":"GHSA-9qq2-xhmc-h9qr","summary":"Access Control Bypass","details":"An issue was discovered in Rancher 2 through 2.1.5. Any project member with access to the default namespace can mount the netes-default service account in a pod, and then use that pod to execute administrative privileged commands against the k8s cluster. This could be mitigated by isolating the default namespace in a separate project, where only cluster admins can be given permissions to access. As of 2018-12-20, this bug affected ALL clusters created or imported by Rancher.","aliases":["CVE-2018-20321","GO-2022-0644"],"modified":"2024-08-21T15:57:38.275067Z","published":"2021-06-23T17:57:10Z","database_specific":{"github_reviewed_at":"2021-05-12T18:10:58Z","nvd_published_at":"2019-04-10T14:29:00Z","cwe_ids":["CWE-288","CWE-668"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-20321"},{"type":"WEB","url":"https://github.com/rancher/rancher/commit/6ea187fcc2309d5a7a14ed47de5688bf6573f448"},{"type":"WEB","url":"https://forums.rancher.com/c/announcements"},{"type":"PACKAGE","url":"https://github.com/rancher/rancher"},{"type":"WEB","url":"https://github.com/rancher/rancher/releases/tag/v2.1.6"},{"type":"WEB","url":"https://rancher.com/blog/2019/2019-01-29-explaining-security-vulnerabilities-addressed-in-rancher-v2-1-6-and-v2-0-11"}],"affected":[{"package":{"name":"github.com/rancher/rancher","ecosystem":"Go","purl":"pkg:golang/github.com/rancher/rancher"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.1.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/06/GHSA-9qq2-xhmc-h9qr/GHSA-9qq2-xhmc-h9qr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
