CVE-2023-32199 Â (opens in a new tab)How to fix?
Upgrade github.com/rancher/rancher/pkg/rbac to version 2.11.7-alpha2, 2.12.3-alpha2 or higher.
Overview
Affected versions of this package are vulnerable to Improper Preservation of Permissions due to the improper removal of ClusterRoleBinding objects when a custom administrative global role or its binding is deleted. An attacker can retain unauthorized access to clusters by leveraging orphaned ClusterRoleBinding entries that persist after the intended permissions have been revoked.
Workaround
This vulnerability can be mitigated by manually identifying and removing orphaned ClusterRoleBindings that are annotated with 'authz.cluster.cattle.io/admin-globalrole-missing=true'.
