From 2.2.0 until 2.2.2, cluster_apiserver_proxy forwarded an authenticated non-administrator's requests to a selected Kubernetes cluster without a resource-level authorization check. The proxy used a reachable worker's Kubernetes ServiceAccount credentials, so the caller could read sensitive resources, create or modify workloads, or delete resources according to that ServiceAccount's permissions. Exploitation required a Kubernetes-provider cluster with a reachable worker, and attacker-controlled workloads could result in code execution in the target cluster. This issue is fixed in version 2.2.2.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/gpustack/gpustack/commit/363191fa1da7e1426c6041f78b3cf00aff2622fe","tags":[]},{"url":"https://github.com/gpustack/gpustack/commit/cdd67467e0f314609dc82216e142940d321abfed","tags":[]},{"url":"https://github.com/gpustack/gpustack/pull/5911","tags":[]},{"url":"https://github.com/gpustack/gpustack/pull/5936","tags":[]},{"url":"https://github.com/gpustack/gpustack/releases/tag/v2.2.2","tags":[]},{"url":"https://github.com/gpustack/gpustack/security/advisories/GHSA-3hch-x692-6qj3","tags":[]}],"exploitRefs":[{"url":"https://github.com/gpustack/gpustack/commit/363191fa1da7e1426c6041f78b3cf00aff2622fe","tags":[]},{"url":"https://github.com/gpustack/gpustack/commit/cdd67467e0f314609dc82216e142940d321abfed","tags":[]},{"url":"https://github.com/gpustack/gpustack/pull/5911","tags":[]},{"url":"https://github.com/gpustack/gpustack/pull/5936","tags":[]},{"url":"https://github.com/gpustack/gpustack/releases/tag/v2.2.2","tags":[]},{"url":"https://github.com/gpustack/gpustack/security/advisories/GHSA-3hch-x692-6qj3","tags":[]}],"hasPoc":true,"ai":null}
