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-2021-3719 in the wild and no public exploit code.\n\nAffected product: Lenovo ThinkCentre and ThinkStation 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-2021-3719/ (Markdown: https://insights.sbomify.com/CVE-2021-3719/index.md)","id":"CVE-2021-3719","markdown":"https://insights.sbomify.com/CVE-2021-3719/index.md","name":"CVE-2021-3719","record":{"aliases":["GHSA-rrvf-m2c7-c86r"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo BIOS","requires_auth":"high_privilege","summary":"Local attackers with elevated privileges can execute arbitrary code via a vulnerability in the BIOS SMI callback function during sleep state resumption.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"thinkcentre_e93_firmware","vendor":"lenovo"},{"product":"thinkcentre_m4500q_firmware","vendor":"lenovo"},{"product":"thinkcentre_m600_firmware","vendor":"lenovo"},{"product":"thinkcentre_m6500t\\/s_firmware","vendor":"lenovo"},{"product":"thinkcentre_m700_tiny_firmware","vendor":"lenovo"},{"product":"thinkcentre_m73_firmware","vendor":"lenovo"},{"product":"thinkcentre_m73p_firmware","vendor":"lenovo"},{"product":"thinkcentre_m800_firmware","vendor":"lenovo"},{"product":"thinkcentre_m818z_firmware","vendor":"lenovo"},{"product":"thinkcentre_m83_firmware","vendor":"lenovo"},{"product":"thinkcentre_m8500t\\/s_firmware","vendor":"lenovo"},{"product":"thinkcentre_m900_firmware","vendor":"lenovo"},{"product":"thinkcentre_m900x_firmware","vendor":"lenovo"},{"product":"thinkcentre_m93_firmware","vendor":"lenovo"},{"product":"thinkcentre_m93p_firmware","vendor":"lenovo"},{"product":"thinkcentre_x1_firmware","vendor":"lenovo"},{"product":"thinkstation_p300_firmware","vendor":"lenovo"},{"product":"thinkstation_p500_firmware","vendor":"lenovo"},{"product":"thinkstation_p700_firmware","vendor":"lenovo"},{"product":"thinkstation_p900_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-20","name":"Improper Input Validation"}],"description":"A potential vulnerability in the SMI callback function that saves and restore boot script tables used for resuming from sleep state in some ThinkCentre and ThinkStation models may allow an attacker with local access and elevated privileges to execute arbitrary code.","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":"Code injection in ThinkCentre and ThinkStation BIOS","id":"CVE-2021-3719","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Legion Phone Pro (L79031)","id":"CVE-2021-3720"},"packages":[],"prev":{"headline":"Denial of service in ThinkPad BIOS","id":"CVE-2021-3718"},"products":["ThinkCentre and ThinkStation BIOS"],"published":"2021-11-12","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":"Local attackers with elevated privileges can execute arbitrary code via a vulnerability in the BIOS SMI callback function during sleep state resumption.","url":"https://insights.sbomify.com/CVE-2021-3719/"}
