{"id":"GHSA-833c-xh79-p429","summary":"A potential risk in clusternet which can be leveraged to make a cluster-level privilege escalation","details":"## Summary:\nA potential risk in clusternet which can be leveraged to make a cluster-level privilege escalation.\n## Detailed analysis:\nThe clusternet has a deployment called cluster-hub inside the clusternet-system Kubernetes namespace, which runs on worker nodes\nrandomly. The deployment has a service account called clusternet-hub, which has a cluster role called clusternet:hub via cluster role binding. The clusternet:hub cluster role has \"*\" verbs of \"*.*\" resources. Thus, if a malicious user can access the worker node which runs the clusternet, he/she can leverage the service account to do malicious actions to critical system resources. For example, he/she can leverage the service account to get ALL secrets in the entire cluster, resulting in cluster-level privilege escalation.","aliases":["CVE-2023-30622","GO-2023-1735"],"modified":"2026-09-10T03:49:53.632486979Z","published":"2023-04-21T19:42:10Z","database_specific":{"nvd_published_at":"2023-04-24T16:15:07Z","cwe_ids":["CWE-269"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-04-21T19:42:10Z"},"references":[{"type":"WEB","url":"https://github.com/clusternet/clusternet/security/advisories/GHSA-833c-xh79-p429"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30622"},{"type":"PACKAGE","url":"https://github.com/clusternet/clusternet"},{"type":"WEB","url":"https://github.com/clusternet/clusternet/releases/tag/v0.15.2"}],"affected":[{"package":{"name":"github.com/clusternet/clusternet","ecosystem":"Go","purl":"pkg:golang/github.com/clusternet/clusternet"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.15.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/04/GHSA-833c-xh79-p429/GHSA-833c-xh79-p429.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L"}]}
