It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-41357 in the wild since at least 25 Apr 2022.\n\nAffected product: Microsoft Windows 10 20h2. 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-2021-41357/ (Markdown: https://insights.sbomify.com/CVE-2021-41357/index.md)","id":"CVE-2021-41357","markdown":"https://insights.sbomify.com/CVE-2021-41357/index.md","name":"CVE-2021-41357","record":{"aliases":["GHSA-pph6-grp2-wvvw"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows OS","requires_auth":"low_privilege","summary":"An attacker can exploit a flaw in the Win32k component 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_2004","vendor":"microsoft"},{"product":"windows_10_20h2","vendor":"microsoft"},{"product":"windows_10_21h1","vendor":"microsoft"},{"product":"windows_11_21h2","vendor":"microsoft"},{"product":"windows_server_2004","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_20h2","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:F/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Win32k Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2021-41357","indexable":true,"kev":{"dateAdded":"2022-04-25","dueDate":"2022-05-16","knownRansomwareCampaignUse":"Unknown","product":"Win32k","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Win32k Privilege Escalation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_20h2","products":["microsoft:windows_10_20h2","microsoft:windows_10_21h1","microsoft:windows_11_21h2","microsoft:windows_server_2022","microsoft:windows_server_20h2"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"HEVC Video Extensions Remote Code Execution Vulnerability","id":"CVE-2021-41360"},"packages":[],"prev":{"headline":"Windows Denial of Service Vulnerability","id":"CVE-2021-41356"},"products":["Windows 10 Version 2004","Windows 10 Version 20H2","Windows 10 Version 21H1","Windows 11 version 21H2","Windows Server 2022","Windows Server version 2004","Windows Server version 20H2"],"published":"2021-10-13","related":[{"cvss_score":9.8,"headline":"Microsoft HTTP Protocol Stack Remote Code Execution","id":"CVE-2021-31166","kev_date_added":"2022-04-06","published":"2021-05-11"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Microsoft"]},"summary":"An attacker can exploit a flaw in the Win32k component to elevate privileges on affected Windows operating systems.","url":"https://insights.sbomify.com/CVE-2021-41357/"}
