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-2022-4575 in the wild and no public exploit code.\n\nAffected product: Lenovo ThinkPad 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-2022-4575/ (Markdown: https://insights.sbomify.com/CVE-2022-4575/index.md)","id":"CVE-2022-4575","markdown":"https://insights.sbomify.com/CVE-2022-4575/index.md","name":"CVE-2022-4575","record":{"aliases":["GHSA-4m6r-j49h-94c5"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ThinkPad BIOS","requires_auth":"high_privilege","summary":"Attackers with local elevated privileges can bypass Secure Boot due to improper write protection of UEFI variables in Lenovo ThinkPad BIOS.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"thinkpad_25_firmware","vendor":"lenovo"},{"product":"thinkpad_l560_firmware","vendor":"lenovo"},{"product":"thinkpad_p50_firmware","vendor":"lenovo"},{"product":"thinkpad_p50s_firmware","vendor":"lenovo"},{"product":"thinkpad_p70_firmware","vendor":"lenovo"},{"product":"thinkpad_t470_firmware","vendor":"lenovo"},{"product":"thinkpad_t470s_firmware","vendor":"lenovo"},{"product":"thinkpad_t560_firmware","vendor":"lenovo"},{"product":"thinkpad_x1_carbon_4th_gen_firmware","vendor":"lenovo"},{"product":"thinkpad_x1_yoga_1st_gen_firmware","vendor":"lenovo"},{"product":"thinkpad_x260_firmware","vendor":"lenovo"},{"product":"thinkpad_x270_firmware","vendor":"lenovo"},{"product":"thinkpad_yoga_260_firmware","vendor":"lenovo"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A vulnerability due to improper write protection of UEFI variables was reported in the BIOS of some ThinkPad models could allow an attacker with physical or local access and elevated privileges the ability to bypass Secure Boot.","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 BIOS","id":"CVE-2022-4575","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Easy Bootstrap Shortcode \u003c= 4.5.4 - Contributor+ Stored XSS","id":"CVE-2022-4576"},"packages":[],"prev":{"headline":"Other in ThinkPad BIOS","id":"CVE-2022-4574"},"products":["ThinkPad BIOS"],"published":"2023-10-30","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Lenovo"]},"summary":"Attackers with local elevated privileges can bypass Secure Boot due to improper write protection of UEFI variables in Lenovo ThinkPad BIOS.","url":"https://insights.sbomify.com/CVE-2022-4575/"}
