It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2018-8453 in the wild since at least 21 Jan 2022, including in ransomware campaigns.\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-2018-8453/ (Markdown: https://insights.sbomify.com/CVE-2018-8453/index.md)","id":"CVE-2018-8453","markdown":"https://insights.sbomify.com/CVE-2018-8453/index.md","name":"CVE-2018-8453","record":{"aliases":["GHSA-8587-44mr-xf6j"],"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":"none","summary":"An attacker can exploit improper memory handling in the Win32k component to elevate privileges on affected Windows systems.","user_interaction":"required","vuln_class":"privilege_escalation"},"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_1703","vendor":"microsoft"},{"product":"windows_10_1709","vendor":"microsoft"},{"product":"windows_10_1803","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_1709","vendor":"microsoft"},{"product":"windows_server_1803","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:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory, aka \"Win32k Elevation of Privilege Vulnerability.\" This affects Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2019, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10, Windows 10 Servers.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2018-10-09","github_poc":3,"max_poc_stars":119,"metasploit":1,"nuclei":0,"refs":[{"date":"2019-01-18T10:40:03Z","kind":"github_poc","ref":"https://github.com/ze0r/cve-2018-8453-exp","stars":119,"title":"cve-2018-8453 exp"},{"date":"2019-07-08T13:06:10Z","kind":"github_poc","ref":"https://github.com/thepwnrip/leHACK-Analysis-of-CVE-2018-8453","stars":14,"title":null},{"date":"2019-01-18T05:24:22Z","kind":"github_poc","ref":"https://github.com/Mkv4/cve-2018-8453-exp","stars":2,"title":"cve-2018-8453 exp"},{"date":"2018-10-09","kind":"metasploit","ref":"exploit/windows/local/cve_2018_8453_win32k_priv_esc","stars":null,"title":"Windows NtUserSetWindowFNID Win32k User Callback"},{"date":"2019-07-17","kind":"exploitdb","ref":"47134","stars":null,"title":"Microsoft Windows -
