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-2023-40220 in the wild and no public exploit code.\n\nAffected product: Intel(R) NUC BIOS firmware. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-40220/ (Markdown: https://insights.sbomify.com/CVE-2023-40220/index.md)","id":"CVE-2023-40220","markdown":"https://insights.sbomify.com/CVE-2023-40220/index.md","name":"CVE-2023-40220","record":{"aliases":["GHSA-xmm7-2j6p-p24v"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel NUC BIOS","requires_auth":"high_privilege","summary":"A privileged local attacker can exploit improper buffer restrictions in Intel NUC BIOS firmware to disclose sensitive information.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"nuc6cayh_firmware","vendor":"intel"},{"product":"nuc6cays_firmware","vendor":"intel"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-92","name":"DEPRECATED: Improper Sanitization of Custom Special Characters"}],"description":"Improper buffer restrictions in some Intel(R) NUC BIOS firmware may allow a privileged user to potentially enable information disclosure via local access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Information disclosure in Intel(R) NUC BIOS firmware","id":"CVE-2023-40220","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Socomec MOD3GP-SY-120K Code Injection","id":"CVE-2023-40221"},"packages":[],"prev":{"headline":"File upload in Welcart e-Commerce","id":"CVE-2023-40219"},"products":["Intel(R) NUC BIOS firmware"],"published":"2023-11-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-14","vendors":["n/a"]},"summary":"A privileged local attacker can exploit improper buffer restrictions in Intel NUC BIOS firmware to disclose sensitive information.","url":"https://insights.sbomify.com/CVE-2023-40220/"}
