Published

An Improper Privilege Management vulnerability in SUSE Rancher allowed standard users to leverage their existing permissions to manipulate Kubernetes secrets in the local cluster, resulting in the secret being deleted, but their read-level permissions to the secret being preserved. When this operation was followed-up by other specially crafted commands, it could result in the user gaining access to tokens belonging to service accounts in the local cluster. This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

### Impact A vulnerability has been identified which enables [Standard users](https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/manage-role-based-access-control-rbac/global-permissions) or above to elevate their permissions to Administrator in the `local` cluster. The `local` cluster means the cluster where Rancher is installed. It is named `local` inside the list of clusters in the Rancher UI. Standard users could leverage their existing permissions to manipulate Kubernetes secrets in the `local` cluster, resulting in the secret being deleted, but their read-level permissions to the secret being preserved. When this operation was followed-up by other specially crafted commands, it could result in the user gaining access to tokens belonging to service accounts in the `local` cluster. Users that have custom global roles which grant `create` and `delete` permissions on `secrets` would also be able to exploit this vulnerability. Users with [audit logs enabled](https://ranchermanager.docs.rancher.com/how-to-guides/advanced-user-guides/enable-api-audit-log#enabling-api-audit-log) in Rancher can try to identify possible abuses of this issue by going through the logs. To sieve through the data filter by `kind: Secret` with `type: provisioning.cattle.io/cloud-credential`, then investigate all log entries that affect that specific resource. A secondary check would be to filter by all operations with `Opaque` Secrets within the `cattle-global-data` namespace. After patching, it is recommended that users review access methods to Rancher (including RBAC policies, tokens, and host-level node access), to ensure that no changes were made to persist access to users who have leveraged this vulnerability. ### Patches Patched versions include releases `2.6.13`, `2.7.4` and later versions. ### Workarounds There is no direct mitigation besides updating Rancher to a patched version. ### For more information If you have any questions or comments about this advisory: - Reach out to the [SUSE Rancher Security team](https://github.com/rancher/rancher/security/policy) for security related inquiries. - Open an issue in the [Rancher](https://github.com/rancher/rancher/issues/new/choose) repository. - Verify with our [support matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/) and [product support lifecycle](https://www.suse.com/lifecycle/).
