Due to improper TLS certificate management, a compromised virt-handler could impersonate virt-api by using its own TLS credentials, allowing it to initiate privileged operations against another virt-handler.
_Short summary of the problem. Make the impact and severity as clear as possible. A flawed implementation of the Kubernetes aggregation layer's authentication flow could enable bypassing RBAC controls.
An issue in kubevirt kubevirt v1.2.0 and before allows a local attacker to execute arbitrary code via a crafted command to get the token component.
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 …
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.
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 …
As part of a Kubevirt audit performed by NCC group, a finding dealing with systemic lack of path sanitization which leads to a path traversal was identified. Google tested the exploitability of the paths in the audit report and identified that when combined with another vulnerability one of the paths leads to an arbitrary file read on the host from the VM. The read operations are limited to files which …
Relative Path Traversal in kubevirt.io/kubevirt.
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.
