Vulnerability Title
KubeVirt Excessive Role Permissions Could Enable Unauthorized VMI Migrations Between Nodes
Source: CVE Program / CVE List V5
Vulnerability Description
KubeVirt is a virtual machine management add-on for Kubernetes. In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.
