Snapshot authentication bypass
CVE: CVE-2021-39226
Component: grafana
CWE: CWE-639
Severity: Important
CVSS v3: 7.3/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Release date: 2021-10-05T00:00:00+00:00

An authentication bypass was found in grafana. An attacker on the network is able to view and delete snapshots by accessing a literal path.

Statement: In OpenShift Container Platform (OCP), Red Hat Advanced Cluster Management for Kubernetes (RHACM), and OpenShift ServiceMesh (OSSM) the grafana components are protected by OpenShift OAuth that reduces the impact of this flaw to Moderate. Access to the grafana panel where snapshots can be created requires admin permissions. Additionally snapshots by default are not available to unauthenticated users and don't contain sensitive data.

Since snapshots by default are not available to unauthenticated users and don't contain sensitive data, impact has been lowered for Red Hat Gluster Storage 3.
