It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-28447 exists.\n\nAffected product: Microsoft Windows 10. 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-2021-28447/ (Markdown: https://insights.sbomify.com/CVE-2021-28447/index.md)","id":"CVE-2021-28447","markdown":"https://insights.sbomify.com/CVE-2021-28447/index.md","name":"CVE-2021-28447","record":{"aliases":["GHSA-pv2w-3wq2-7rvh"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows OS","requires_auth":"high_privilege","summary":"Attackers can bypass Windows Early Launch Antimalware Driver protections, potentially allowing malicious code to load during boot.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows Early Launch Antimalware Driver Security Feature Bypass Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Windows Early Launch Antimalware Driver Security Feature Bypass Vulnerability","id":"CVE-2021-28447","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_7","microsoft:windows_8.1","microsoft:windows_rt_8.1","microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Visual Studio Code Kubernetes Tools Remote Code Execution Vulnerability","id":"CVE-2021-28448"},"packages":[],"prev":{"headline":"Windows Portmapping Information Disclosure Vulnerability","id":"CVE-2021-28446"},"products":["Windows 10 Version 1507","Windows 10 Version 1607","Windows 10 Version 1803","Windows 10 Version 1809","Windows 10 Version 1909","Windows 10 Version 2004","Windows 10 Version 20H2","Windows 8.1","Windows Server 2012","Windows Server 2012 (Server Core installation)","Windows Server 2012 R2","Windows Server 2012 R2 (Server Core installation)","Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server version 2004","Windows Server version 20H2","Windows Server, version 1909 (Server Core installation)"],"published":"2021-04-13","related":[{"cvss_score":8.8,"headline":"Microsoft Windows Adobe Type Manager Library Remote Code Execution","id":"CVE-2015-2426","kev_date_added":"2022-03-28","published":"2015-07-20"},{"cvss_score":6.6,"headline":"Microsoft Windows Mount Manager Privilege Escalation","id":"CVE-2015-1769","kev_date_added":"2022-05-25","published":"2015-08-15"},{"cvss_score":10,"headline":"Windows Hard Link Elevation of Privilege Vulnerability","id":"CVE-2020-1467","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":9.9,"headline":"Windows TCP/IP Remote Code Execution Vulnerability","id":"CVE-2021-26424","kev_date_added":null,"published":"2021-08-12"},{"cvss_score":9.9,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2021-28476","kev_date_added":null,"published":"2021-05-11"},{"cvss_score":9.9,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2021-26867","kev_date_added":null,"published":"2021-03-11"},{"cvss_score":9.9,"headline":"Security feature bypass in Windows","id":"CVE-2019-1384","kev_date_added":null,"published":"2019-11-12"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["Microsoft"]},"summary":"Attackers can bypass Windows Early Launch Antimalware Driver protections, potentially allowing malicious code to load during boot.","url":"https://insights.sbomify.com/CVE-2021-28447/"}
