Name Description
CVE-2024-31420 A NULL pointer dereference flaw was found in KubeVirt. This flaw allows an attacker who has access to a virtual machine guest on a node with DownwardMetrics enabled to cause a denial of service by issuing a high number of calls to vm-dump-metrics --virtio and then deleting the virtual machine.
CVE-2024-1725 A flaw was found in the kubevirt-csi component of OpenShift Virtualization's Hosted Control Plane (HCP). This issue could allow an authenticated attacker to gain access to the root HCP worker node's volume by creating a custom Persistent Volume that matches the name of a worker node.
CVE-2023-26484 KubeVirt is a virtual machine management add-on for Kubernetes. In versions 0.59.0 and prior, if a malicious user has taken over a Kubernetes node where virt-handler (the KubeVirt node-daemon) is running, the virt-handler service account can be used to modify all node specs. This can be misused to lure-in system-level-privileged components which can, for instance, read all secrets on the cluster, or can exec into pods on other nodes. This way, a compromised node can be used to elevate privileges beyond the node until potentially having full privileged access to the whole cluster. The simplest way to exploit this, once a user could compromise a specific node, is to set with the virt-handler service account all other nodes to unschedulable and simply wait until system-critical components with high privileges appear on its node. No patches are available as of time of publication. As a workaround, gatekeeper users can add a webhook which will block the `virt-handler` service account to modify the spec of a node.
CVE-2022-1798 A path traversal vulnerability in KubeVirt versions up to 0.56 (and 0.55.1) on all platforms allows a user able to configure the kubevirt to read arbitrary files on the host filesystem which are publicly readable or which are readable for UID 107 or GID 107. /proc/self/<> is not accessible.
CVE-2021-20238 It was found in OpenShift Container Platform 4 that ignition config, served by the Machine Config Server, can be accessed externally from clusters without authentication. The MCS endpoint (port 22623) provides ignition configuration used for bootstrapping Nodes and can include some sensitive data, e.g. registry pull secrets. There are two scenarios where this data can be accessed. The first is on Baremetal, OpenStack, Ovirt, Vsphere and KubeVirt deployments which do not have a separate internal API endpoint and allow access from outside the cluster to port 22623 from the standard OpenShift API Virtual IP address. The second is on cloud deployments when using unsupported network plugins, which do not create iptables rules that prevent to port 22623. In this scenario, the ignition config is exposed to all pods within the cluster and cannot be accessed externally.
CVE-2020-1701 A flaw was found in the KubeVirt main virt-handler versions before 0.26.0 regarding the access permissions of virt-handler. An attacker with access to create VMs could attach any secret within their namespace, allowing them to read the contents of that secret.
CVE-2020-14316 A flaw was found in kubevirt 0.29 and earlier. Virtual Machine Instances (VMIs) can be used to gain access to the host's filesystem. Successful exploitation allows an attacker to assume the privileges of the VM process on the host system. In worst-case scenarios an attacker can read and modify any file on the system where the VMI is running. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2019-3841 Kubevirt/virt-cdi-importer, versions 1.4.0 to 1.5.3 inclusive, were reported to disable TLS certificate validation when importing data into PVCs from container registries. This could enable man-in-the-middle attacks between a container registry and the virt-cdi-component, leading to possible undetected tampering of trusted container image content.
