It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-27593 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.11.15\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.11.15\n- github.com/cilium/cilium (Go): affected from 1.12.0; fixed in 1.12.8\n- github.com/cilium/cilium (Go): affected from 1.12.0; fixed in 1.12.8\n- github.com/cilium/cilium (Go): affected from 1.13.0; fixed in 1.13.1\n- github.com/cilium/cilium (Go): affected from 1.13.0; fixed in 1.13.1\n- cilium (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\n- cilium-operator (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\n- cilium-proxy (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\n- hubble (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\n- hubble-relay (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\n- hubble-ui (Bitnami): affected all versions; fixed in 1.11.15, 1.12.8, 1.13.1\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-2023-27593/ (Markdown: https://insights.sbomify.com/CVE-2023-27593/index.md)","id":"CVE-2023-27593","markdown":"https://insights.sbomify.com/CVE-2023-27593/index.md","name":"CVE-2023-27593","record":{"aliases":["BIT-cilium-2023-27593","BIT-cilium-operator-2023-27593","BIT-cilium-proxy-2023-27593","BIT-hubble-2023-27593","BIT-hubble-relay-2023-27593","BIT-hubble-ui-2023-27593","BIT-hubble-ui-backend-2023-27593","GHSA-4hc4-pgfx-3mrx"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cilium networking","requires_auth":"high_privilege","summary":"An attacker with pod access can replace CNI binaries via hostPath mount to execute code on the underlying node.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cilium","vendor":"cilium"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.11.15, 1.12.8, and 1.13.1, an attacker with access to a Cilium agent pod can write to `/opt/cni/bin` due to a `hostPath` mount of that directory in the agent pod. By replacing the CNI binary with their own malicious binary and waiting for the creation of a new pod on the node, the attacker can gain access to the underlying node.\n\nThe issue has been fixed and the fix is available on versions 1.11.15, 1.12.8, and 1.13.1. Some workarounds are available. Kubernetes RBAC should be used to deny users and service accounts `exec` access to Cilium agent pods. In cases where a user requires `exec` access to Cilium agent pods, but should not have access to the underlying node, no workaround is possible.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"cilium-agent
