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.

GHSA-p976-h52c-26p6 — Rancher vulnerable to Privilege Escalation via manipulation of Secrets

Affected: Go: github.com/rancher/rancher

### 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`…
