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-2021-27090 in the wild and no public exploit code.\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-2021-27090/ (Markdown: https://insights.sbomify.com/CVE-2021-27090/index.md)","id":"CVE-2021-27090","markdown":"https://insights.sbomify.com/CVE-2021-27090/index.md","name":"CVE-2021-27090","record":{"aliases":["GHSA-7hrm-vjjg-h867"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Secure Kernel","requires_auth":"low_privilege","summary":"An attacker can exploit a vulnerability in Windows Secure Kernel Mode to elevate privileges on affected Windows systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"}],"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/E:U/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","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":"Windows Secure Kernel Mode Elevation of Privilege Vulnerability","id":"CVE-2021-27090","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_server_2016"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"RPC Endpoint Mapper Service Elevation of Privilege Vulnerability","id":"CVE-2021-27091"},"packages":[],"prev":{"headline":"Microsoft Internet Messaging API Remote Code Execution Vulnerability","id":"CVE-2021-27089"},"products":["Windows 10 Version 2004","Windows 10 Version 20H2","Windows Server version 2004","Windows Server version 20H2"],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Microsoft"]},"summary":"An attacker can exploit a vulnerability in Windows Secure Kernel Mode to elevate privileges on affected Windows systems.","url":"https://insights.sbomify.com/CVE-2021-27090/"}
