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-2021-1646 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-2021-1646/ (Markdown: https://insights.sbomify.com/CVE-2021-1646/index.md)","id":"CVE-2021-1646","markdown":"https://insights.sbomify.com/CVE-2021-1646/index.md","name":"CVE-2021-1646","record":{"aliases":["GHSA-jxp8-5wq4-2jcf"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows WLAN Service","requires_auth":"low_privilege","summary":"An attacker can exploit the Windows WLAN Service to elevate privileges on affected Windows operating 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"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Windows WLAN Service 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 WLAN Service Elevation of Privilege Vulnerability","id":"CVE-2021-1646","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Defender Remote Code Execution","id":"CVE-2021-1647"},"packages":[],"prev":{"headline":"Windows Docker Information Disclosure Vulnerability","id":"CVE-2021-1645"},"products":["Windows 10 Version 1803","Windows 10 Version 1809","Windows 10 Version 1909","Windows 10 Version 2004","Windows 10 Version 20H2","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":"2021-01-12","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-19","vendors":["Microsoft"]},"summary":"An attacker can exploit the Windows WLAN Service to elevate privileges on affected Windows operating systems.","url":"https://insights.sbomify.com/CVE-2021-1646/"}
