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-2020-8334 in the wild and no public exploit code.\n\nAffected product: Lenovo BIOS. 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-2020-8334/ (Markdown: https://insights.sbomify.com/CVE-2020-8334/index.md)","id":"CVE-2020-8334","markdown":"https://insights.sbomify.com/CVE-2020-8334/index.md","name":"CVE-2020-8334","record":{"aliases":["GHSA-9x9m-j8v4-cx96"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo ThinkPad BIOS","requires_auth":"none","summary":"Attackers can bypass BIOS tamper detection on specific Lenovo ThinkPad models, potentially enabling unauthorized physical access to the device.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"thinkpad_a275_firmware","vendor":"lenovo"},{"product":"thinkpad_a285_firmware","vendor":"lenovo"},{"product":"thinkpad_a475_firmware","vendor":"lenovo"},{"product":"thinkpad_a485_firmware","vendor":"lenovo"},{"product":"thinkpad_t495_firmware","vendor":"lenovo"},{"product":"thinkpad_t495s_firmware","vendor":"lenovo"},{"product":"thinkpad_x395_firmware","vendor":"lenovo"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad T495s, X395, T495, A485, A285, A475, A275 which may allow for unauthorized 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":"Security feature bypass in BIOS","id":"CVE-2020-8334","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in ThinkPad A285 BIOS","id":"CVE-2020-8335"},"packages":[],"prev":{"headline":"Code injection in BIOS","id":"CVE-2020-8333"},"products":["BIOS"],"published":"2020-06-09","related":[{"cvss_score":6.1,"headline":"Security feature bypass in ThinkPad A285 BIOS","id":"CVE-2020-8335","kev_date_added":null,"published":"2020-09-01"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Lenovo"]},"summary":"Attackers can bypass BIOS tamper detection on specific Lenovo ThinkPad models, potentially enabling unauthorized physical access to the device.","url":"https://insights.sbomify.com/CVE-2020-8334/"}
