CVE-2022-0270Network attack vector

Privilege escalation via unsanitized impersonation headers

Published Jan 25, 2022 · Updated Sep 16, 2024

Improper access control in Mirantis bored-agent before 0.6.1 allows remote authenticated users to assume other Kubernetes identities. The agent forwards incoming Kubernetes requests without removing Impersonate-* headers, so client-supplied user and group values override the RBAC identity assigned by Cluster Connect. Valid Cluster Connect access is required; successful exploitation grants the permissions of the impersonated Kubernetes user or groups.
