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-2021-3464 in the wild and no public exploit code.\n\nAffected product: Lenovo PCManager. 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-2021-3464/ (Markdown: https://insights.sbomify.com/CVE-2021-3464/index.md)","id":"CVE-2021-3464","markdown":"https://insights.sbomify.com/CVE-2021-3464/index.md","name":"CVE-2021-3464","record":{"aliases":["GHSA-jrv3-mp53-r7jv"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo PCManager","requires_auth":"low_privilege","summary":"A DLL search path vulnerability in Lenovo PCManager allows attackers to achieve privilege escalation by exploiting insecure library loading mechanisms.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"pcmanager","vendor":"lenovo"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A DLL search path vulnerability was reported in Lenovo PCManager, prior to version 3.0.400.3252, that could allow privilege escalation.","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":"Privilege escalation in PCManager","id":"CVE-2021-3464","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-3465"},"packages":[],"prev":{"headline":"Null dereference in Power Management Driver for Windows 10","id":"CVE-2021-3463"},"products":["PCManager"],"published":"2021-04-27","related":[{"cvss_score":8.5,"headline":"Privilege escalation in PC Manager","id":"CVE-2025-10581","kev_date_added":null,"published":"2025-10-15"},{"cvss_score":8.5,"headline":"Privilege escalation in PC Manager","id":"CVE-2025-8486","kev_date_added":null,"published":"2025-10-15"},{"cvss_score":8.5,"headline":"Privilege escalation in PC Manager","id":"CVE-2025-8098","kev_date_added":null,"published":"2025-08-18"},{"cvss_score":8.5,"headline":"Privilege escalation in PC Manager","id":"CVE-2025-2501","kev_date_added":null,"published":"2025-05-30"},{"cvss_score":8.5,"headline":"Privilege escalation in PC Manager","id":"CVE-2025-2502","kev_date_added":null,"published":"2025-05-30"},{"cvss_score":7.8,"headline":"Privilege escalation in PC Manager","id":"CVE-2019-6197","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":7.8,"headline":"Privilege escalation in PC Manager","id":"CVE-2019-6198","kev_date_added":null,"published":"2024-07-31"}],"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":"A DLL search path vulnerability in Lenovo PCManager allows attackers to achieve privilege escalation by exploiting insecure library loading mechanisms.","url":"https://insights.sbomify.com/CVE-2021-3464/"}
