Description
An authentication bypass flaw was discovered in the crewjam/saml go package. A remote unauthenticated attacker could trigger it by sending a SAML request. This would allow an escalation of privileges and then enable compromising system integrity.
Statement
Whilst the Red Hat Advanced Cluster Management for Kubernetes (RHACM) acm-grafana container include the vulnerable underscore library, the access to it is protected by OpenShift OAuth. Therefore the impact by this flaw is reduced from Critical to Important.
The OCP grafana-container includes the vulnerable underscore library, the access to it is protected by OpenShift OAuth. Therefore the impact by this flaw is reduced from Critical to Important.
While Red Hat Ceph Storage 4's grafana-container includes the affected code, this is used for logging and limits access to the rest of the Ceph cluster. Thus the impact has been reduced from critical to important. Red Hat Ceph Storage 3 and 4 do not use crewjam/saml in their version of grafana.
