It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2016-0099 in the wild since at least 3 Mar 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-2016-0099/ (Markdown: https://insights.sbomify.com/CVE-2016-0099/index.md)","id":"CVE-2016-0099","markdown":"https://insights.sbomify.com/CVE-2016-0099/index.md","name":"CVE-2016-0099","record":{"aliases":["GHSA-fq5j-826m-h5wc"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Secondary Logon","requires_auth":"low_privilege","summary":"Local attackers can gain elevated privileges by exploiting improper handle processing in the Windows Secondary Logon Service.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1507","vendor":"microsoft"},{"product":"windows_10_1511","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_vista","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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"The Secondary Logon Service in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold and 1511 does not properly process request handles, which allows local users to gain privileges via a crafted application, aka \"Secondary Logon Elevation of Privilege Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2016-03-21","github_poc":1,"max_poc_stars":83,"metasploit":1,"nuclei":0,"refs":[{"date":"2017-03-15T17:16:55Z","kind":"github_poc","ref":"https://github.com/zcgonvh/MS16-032","stars":83,"title":"MS16-032(CVE-2016-0099) for SERVICE ONLY"},{"date":"2016-03-21","kind":"exploitdb","ref":"39574","stars":null,"title":"Microsoft Windows 8.1/10 (x86) -
