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."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","baseScore":8.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":5.8},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","baseScore":8.2,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":5.8}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-863"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:kubevirt:kubevirt:*:*:*:*:*:kubernetes:*:*","versionEndIncluding":"0.59.0","matchCriteriaId":"B0C470F6-1D95-437E-9A57-D0075ED16482"}]}]}],"references":[{"url":"https://github.com/kubevirt/kubevirt/issues/9109","source":"security-advisories@github.com","tags":["Issue Tracking","Third Party Advisory"]},{"url":"https://github.com/kubevirt/kubevirt/security/advisories/GHSA-cp96-jpmq-xrr2","source":"security-advisories@github.com","tags":["Mitigation","Vendor Advisory"]},{"url":"https://github.com/kubevirt/kubevirt/issues/9109","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Third Party Advisory"]},{"url":"https://github.com/kubevirt/kubevirt/security/advisories/GHSA-cp96-jpmq-xrr2","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mitigation","Vendor Advisory"]}]}}]}
