It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-0638 in the wild since at least 23 May 2022, including in ransomware campaigns.\n\nAffected product: Microsoft Windows 10 1809. 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-2020-0638/ (Markdown: https://insights.sbomify.com/CVE-2020-0638/index.md)","id":"CVE-2020-0638","markdown":"https://insights.sbomify.com/CVE-2020-0638/index.md","name":"CVE-2020-0638","record":{"aliases":["GHSA-53p9-m4mr-wp8x"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Update Manager","requires_auth":"low_privilege","summary":"An attacker with local access can exploit file handling flaws in the Update Notification Manager to elevate privileges on Windows systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"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_server_1803","vendor":"microsoft"},{"product":"windows_server_1903","vendor":"microsoft"},{"product":"windows_server_1909","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-59","name":"Improper Link Resolution Before File Access"}],"description":"An elevation of privilege vulnerability exists in the way the Update Notification Manager handles files.To exploit this vulnerability, an attacker would first have to gain execution on the victim system, aka 'Update Notification Manager 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 Update Notification Manager Privilege Escalation","id":"CVE-2020-0638","indexable":true,"kev":{"dateAdded":"2022-05-23","dueDate":"2022-06-13","knownRansomwareCampaignUse":"Known","product":"Update Notification Manager","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Update Notification Manager Privilege Escalation Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10_1809","products":["microsoft:windows_10_1809","microsoft:windows_server_2019"],"type":"privilege_escalation","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Windows","id":"CVE-2020-0639"},"packages":[],"prev":{"headline":"Information disclosure in Windows Server","id":"CVE-2020-0637"},"products":["Windows","Windows 10 Version 1903 for 32-bit Systems","Windows 10 Version 1903 for ARM64-based Systems","Windows 10 Version 1903 for x64-based Systems","Windows 10 Version 1909 for 32-bit Systems","Windows 10 Version 1909 for ARM64-based Systems","Windows 10 Version 1909 for x64-based Systems","Windows Server","Windows Server, version 1903 (Server Core installation)","Windows Server, version 1909 (Server Core installation)"],"published":"2020-01-14","related":[{"cvss_score":7.8,"headline":"Microsoft Windows AppX Deployment Extensions Privilege Escalation","id":"CVE-2019-1385","kev_date_added":"2022-05-23","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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Microsoft"]},"summary":"An attacker with local access can exploit file handling flaws in the Update Notification Manager to elevate privileges on Windows systems.","url":"https://insights.sbomify.com/CVE-2020-0638/"}
