Comment 14 Sage McTaggart 2020-09-24 19:34:20 UTC

Statement:

A vulnerable version of Grafana is shipped in OpenShift 3.11 and OpenShift ServiceMesh, however Prometheus is used as a data source and modification to MySQL requires full control of the grafana component. Access is restricted to authenticated users only by OpenShift OAuth. As OpenShift and OpenShift ServiceMesh still packages the vulnerable code, the components are affected but with impact Low. 

Red Hat Ceph Storage 3 and 4 ships an older version of the affected code, which is still possible to exploit. However, Ceph 3 and 4 do not use mysql as a datasource, therefore, the impact is low.

Red Hat Gluster Storage 3 ships vulnerable version of grafana, however Graphite is the only supported data source and hence this issue has been rated as having a security impact of Low.
