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-2020-8335 in the wild and no public exploit code.\n\nAffected product: Lenovo ThinkPad A285 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-2020-8335/ (Markdown: https://insights.sbomify.com/CVE-2020-8335/index.md)","id":"CVE-2020-8335","markdown":"https://insights.sbomify.com/CVE-2020-8335/index.md","name":"CVE-2020-8335","record":{"aliases":["GHSA-fvh7-v69p-hj2v"],"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":"Lenovo ThinkPad BIOS fails to trigger tamper detection when the emergency-reset button is pressed, allowing unauthorized access.","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_drift_firmware","vendor":"lenovo"},{"product":"thinkpad_t495s_jazz_firmware","vendor":"lenovo"},{"product":"thinkpad_x1_carbon_\\(20bx\\)_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":[],"description":"The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad A285, BIOS versions up to r0xuj70w; A485, BIOS versions up to r0wuj65w; T495 BIOS versions up to r12uj55w; T495s/X395, BIOS versions up to r13uj47w, while the emergency-reset button is pressed 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 ThinkPad A285 BIOS","id":"CVE-2020-8335","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 BIOS","id":"CVE-2020-8336"},"packages":[],"prev":{"headline":"Security feature bypass in BIOS","id":"CVE-2020-8334"},"products":["ThinkPad A285 BIOS","ThinkPad A485 BIOS","ThinkPad T495 BIOS","ThinkPad T495s/X395 BIOS"],"published":"2020-09-01","related":[{"cvss_score":6.1,"headline":"Security feature bypass in BIOS","id":"CVE-2020-8334","kev_date_added":null,"published":"2020-06-09"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Lenovo"]},"summary":"Lenovo ThinkPad BIOS fails to trigger tamper detection when the emergency-reset button is pressed, allowing unauthorized access.","url":"https://insights.sbomify.com/CVE-2020-8335/"}
