Описание
A flaw was found in the Observability Operator. The Operator creates a ServiceAccount with ClusterRole upon deployment of the Namespace-Scoped Custom Resource MonitorStack. This issue allows an adversarial Kubernetes Account with only namespaced-level roles, for example, a tenant controlling a namespace, to create a MonitorStack in the authorized namespace and then elevate permission to the cluster level by impersonating the ServiceAccount created by the Operator, resulting in privilege escalation and other issues.
Отчет
Red Hat rates this with an Important impact. Although the attacker may use a previously privileged account, the escalation may lead to broader cluster access.
Меры по смягчению последствий
Currently, no mitigation is available for this vulnerability.
