Описание
A flaw was found in the multicloud-integrations component. The Application propagation controller processes the ocm-managed-cluster annotation from an Application Custom Resource (CR) without proper validation. A tenant with permissions to create Applications on the hub cluster can exploit this to target arbitrary managed clusters. This can force ArgoCD on the spoke clusters to synchronize attacker-controlled manifests, leading to arbitrary code execution or privilege escalation on those clusters.
Отчет
This Critical flaw in Red Hat Advanced Cluster Management's multicloud-integrations component allows a tenant with Application creation permissions on the hub to achieve cluster-admin privileges on any connected spoke cluster. The Application propagation controller fails to validate the ocm-managed-cluster annotation, enabling an attacker to direct ManifestWorks to arbitrary managed clusters. This bypasses authorization, leading to significant privilege escalation across the managed environment.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
