It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-64432 exists.\n\nAffected packages and fixed versions:\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3, 1.6.0-beta.0.0.20250730135146-231dc69723f3, 1.6.1, 1.7.0-rc.0\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3\n- kubevirt.io/kubevirt (Go): affected from 1.6.0-alpha.0; fixed in 1.6.1\n- kubevirt.io/kubevirt (Go): affected from 1.6.0-alpha.0; fixed in 1.6.1\n- kubevirt.io/kubevirt (Go): affected from 1.7.0-alpha.0; fixed in 1.7.0-rc.0\n- kubevirt.io/kubevirt (Go): affected from 1.7.0-alpha.0; fixed in 1.7.0-rc.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-64432/ (Markdown: https://insights.sbomify.com/CVE-2025-64432/index.md)","id":"CVE-2025-64432","markdown":"https://insights.sbomify.com/CVE-2025-64432/index.md","name":"CVE-2025-64432","record":{"aliases":["AZL-69793","AZL-69890","GHSA-38jw-g2qx-4286","GO-2025-4103","MINI-49qg-h42q-vqwf","MINI-5gh3-mc22-wrc6","MINI-6wp7-x896-mw6f","MINI-hq3f-wwjq-6mh2"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kubernetes VM add-on","requires_auth":"low_privilege","summary":"Attackers can bypass RBAC controls in KubeVirt by exploiting flawed mTLS authentication in the virt-api component, allowing unauthorized access to aggregated APIs.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kubevirt","vendor":"kubevirt"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"KubeVirt is a virtual machine management add-on for Kubernetes. Versions 1.5.3 and below, and 1.6.0 contained a flawed implementation of the Kubernetes aggregation layer's authentication flow which could enable bypass of RBAC controls. It was discovered that the virt-api component fails to correctly authenticate the client when receiving API requests over mTLS. In particular, it fails to validate the CN (Common Name) field in the received client TLS certificates against the set of allowed values defined in the extension-apiserver-authentication configmap. Failre to validate certain fields in the client TLS certificate may allow an attacker to bypass existing RBAC controls by directly communicating with the aggregated API server, impersonating the Kubernetes API server and its aggregator component.
