It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-8342 in the wild and no public exploit code.\n\nAffected product: Lenovo System Update. 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-2020-8342/ (Markdown: https://insights.sbomify.com/CVE-2020-8342/index.md)","id":"CVE-2020-8342","markdown":"https://insights.sbomify.com/CVE-2020-8342/index.md","name":"CVE-2020-8342","record":{"aliases":["GHSA-jh9f-947r-wfrf"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo System Update","requires_auth":"low_privilege","summary":"A race condition in Lenovo System Update allows attackers to escalate privileges on affected systems.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"system_update","vendor":"lenovo"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"},{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"A race condition vulnerability was reported in Lenovo System Update prior to version 5.07.0106 that could allow escalation of privilege.","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":"Race condition in System Update","id":"CVE-2020-8342","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-8343"},"packages":[],"prev":{"headline":"Security feature bypass in ThinkPad","id":"CVE-2020-8341"},"products":["System Update"],"published":"2020-09-15","related":[{"cvss_score":8.3,"headline":"Security feature bypass in n/a","id":"CVE-2015-2233","kev_date_added":null,"published":"2015-05-12"},{"cvss_score":7.8,"headline":"Other in Lenovo System Update","id":"CVE-2023-4632","kev_date_added":null,"published":"2023-11-08"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2015-7333","kev_date_added":null,"published":"2020-03-27"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2015-7334","kev_date_added":null,"published":"2020-03-27"},{"cvss_score":7.8,"headline":"Memory corruption in Lenovo System Update","id":"CVE-2018-9063","kev_date_added":null,"published":"2018-05-04"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2015-6971","kev_date_added":null,"published":"2017-10-02"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2015-7336","kev_date_added":null,"published":"2020-03-27"}],"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":"A race condition in Lenovo System Update allows attackers to escalate privileges on affected systems.","url":"https://insights.sbomify.com/CVE-2020-8342/"}
