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-2023-41333 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 1.12.14, 1.13.7, 1.14.2\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.12.14\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.12.14\n- github.com/cilium/cilium (Go): affected from 1.13.0; fixed in 1.13.7\n- github.com/cilium/cilium (Go): affected from 1.13.0; fixed in 1.13.7\n- github.com/cilium/cilium (Go): affected from 1.14.0; fixed in 1.14.2\n- github.com/cilium/cilium (Go): affected from 1.14.0; fixed in 1.14.2\n- cilium (Bitnami): affected all versions; fixed in 1.12.14, 1.13.7, 1.14.2\n- cilium-operator (Bitnami): affected all versions; fixed in 1.12.14, 1.13.7, 1.14.2\n- cilium-proxy (Bitnami): affected all versions; fixed in 1.12.14, 1.13.7, 1.14.2\n- hubble (Bitnami): affected all versions; fixed in 1.12.14, 1.13.7, 1.14.2\n- hubble-relay (Bitnami): affected all versions; fixed in 1.12.14, 1.13.7, 1.14.2\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-2023-41333/ (Markdown: https://insights.sbomify.com/CVE-2023-41333/index.md)","id":"CVE-2023-41333","markdown":"https://insights.sbomify.com/CVE-2023-41333/index.md","name":"CVE-2023-41333","record":{"aliases":["BIT-cilium-2023-41333","BIT-cilium-operator-2023-41333","BIT-cilium-proxy-2023-41333","BIT-hubble-2023-41333","BIT-hubble-relay-2023-41333","BIT-hubble-ui-2023-41333","BIT-hubble-ui-backend-2023-41333","GHSA-4xp2-w642-7mcx","GO-2023-2080"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cilium network policy","requires_auth":"high_privilege","summary":"An attacker with namespace-level API access can bypass Cilium network policy restrictions to affect cluster-wide traffic, requiring an upgrade or admission webhook workaround.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cilium","vendor":"cilium"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to create or modify CiliumNetworkPolicy objects in a particular namespace is able to affect traffic on an entire Cilium cluster, potentially bypassing policy enforcement in other namespaces. By using a crafted `endpointSelector` that uses the `DoesNotExist` operator on the `reserved:init` label, the attacker can create policies that bypass namespace restrictions and affect the entire Cilium cluster. This includes potentially allowing or denying all traffic. This attack requires API server access, as described in the Kubernetes API Server Attacker section of the Cilium Threat Model. This issue has been resolved in Cilium versions 1.14.2, 1.13.7, and 1.12.14. As a workaround an admission webhook can be used to prevent the use of `endpointSelectors` that use the `DoesNotExist` operator on the `reserved:init` label in CiliumNetworkPolicies.","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":"Bypass
