It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-1027 in the wild since at least 23 May 2022.\n\nAffected product: Microsoft Windows 10 1507. 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-2020-1027/ (Markdown: https://insights.sbomify.com/CVE-2020-1027/index.md)","id":"CVE-2020-1027","markdown":"https://insights.sbomify.com/CVE-2020-1027/index.md","name":"CVE-2020-1027","record":{"aliases":["GHSA-4425-fxh6-87fr"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Kernel","requires_auth":"low_privilege","summary":"An attacker can exploit a memory handling flaw in the Windows Kernel to elevate privileges on affected systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1507","vendor":"microsoft"},{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1709","vendor":"microsoft"},{"product":"windows_10_1803","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_10_1903","vendor":"microsoft"},{"product":"windows_10_1909","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_1803","vendor":"microsoft"},{"product":"windows_server_1903","vendor":"microsoft"},{"product":"windows_server_1909","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory, aka 'Windows Kernel Elevation of Privilege Vulnerability'.
