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-2021-3451 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-2021-3451/ (Markdown: https://insights.sbomify.com/CVE-2021-3451/index.md)","id":"CVE-2021-3451","markdown":"https://insights.sbomify.com/CVE-2021-3451/index.md","name":"CVE-2021-3451","record":{"aliases":["GHSA-j6pp-8p4v-4rwc"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lenovo PCManager","requires_auth":"low_privilege","summary":"Attackers can write configuration files to non-standard locations in Lenovo PCManager, causing a denial of service.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"pcmanager","vendor":"lenovo"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A denial of service vulnerability was reported in Lenovo PCManager, prior to version 3.0.400.3252, that could allow configuration files to be written to non-standard locations.","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":"Path traversal in PCManager","id":"CVE-2021-3451","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in ThinkPad BIOS","id":"CVE-2021-3452"},"packages":[],"prev":{"headline":"CA certificate check bypass with X509_V_FLAG_X509_STRICT","id":"CVE-2021-3450"},"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":"Attackers can write configuration files to non-standard locations in Lenovo PCManager, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2021-3451/"}
