{"cve":"CVE-2023-30622","nvd":{"published":"2023-04-24T16:15:07.917","modified":"2026-06-17T05:55:10.420","status":"Modified","description":"Clusternet is a general-purpose system for controlling Kubernetes clusters across different environments. An issue in clusternet prior to version 0.15.2 can be leveraged to lead to a cluster-level privilege escalation. The clusternet has a deployment called `cluster-hub` inside the `clusternet-system` Kubernetes namespace, which runs on worker nodes randomly. 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, they can leverage the service account to do malicious actions to critical system resources. For example, the malicious user can leverage the service account to get ALL secrets in the entire cluster, resulting in cluster-level privilege escalation. Version 0.15.2 contains a fix for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://github.com/clusternet/clusternet/releases/tag/v0.15.2","https://github.com/clusternet/clusternet/security/advisories/GHSA-833c-xh79-p429","https://github.com/clusternet/clusternet/releases/tag/v0.15.2","https://github.com/clusternet/clusternet/security/advisories/GHSA-833c-xh79-p429"],"products":["clusternet:clusternet"],"source":"nvd","synced_at":"2026-10-19T21:38:05.473481323+00:00"},"epss":{"cve":"CVE-2023-30622","score":0.00193,"percentile":0.0903,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-833c-xh79-p429","url":"https://osv.dev/vulnerability/GHSA-833c-xh79-p429","summary":"A potential risk in clusternet which can be leveraged to make a cluster-level privilege escalation","modified":"2026-09-10T03:49:53.632486979Z","packages":[{"ecosystem":"Go","name":"github.com/clusternet/clusternet","purl":"pkg:golang/github.com/clusternet/clusternet","ranges":["<0.15.2"],"fixed":["0.15.2"]}]},{"id":"GO-2023-1735","url":"https://osv.dev/vulnerability/GO-2023-1735","summary":"A potential risk in clusternet which can be leveraged to make a cluster-level privilege escalation in github.com/clusternet/clusternet","modified":"2026-03-03T04:53:38.283250Z","packages":[{"ecosystem":"Go","name":"github.com/clusternet/clusternet","purl":"pkg:golang/github.com/clusternet/clusternet","ranges":["<0.15.2"],"fixed":["0.15.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
