An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-1166 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10. 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-2019-1166/ (Markdown: https://insights.sbomify.com/CVE-2019-1166/index.md)","id":"CVE-2019-1166","markdown":"https://insights.sbomify.com/CVE-2019-1166/index.md","name":"CVE-2019-1166","record":{"aliases":["GHSA-6576-35f2-4q5m"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows NTLM","requires_auth":"none","summary":"Man-in-the-middle attackers can bypass NTLM Message Integrity Check protection in Microsoft Windows, compromising authentication integrity.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","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":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"}],"description":"A tampering vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully bypass the NTLM MIC (Message Integrity Check) protection, aka 'Windows NTLM Tampering Vulnerability'.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Security feature bypass in Windows","id":"CVE-2019-1166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_7","microsoft:windows_8.1","microsoft:windows_rt_8.1","microsoft:windows_server_2008","microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"security_feature_bypass","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"System.Management.Automation subject to bypass via script debugging","id":"CVE-2019-1167"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2019-1165"},"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 Server","Windows Server, version 1903 (Server Core installation)"],"published":"2019-10-10","related":[{"cvss_score":8.8,"headline":"Microsoft Windows Adobe Type Manager Library Remote Code Execution","id":"CVE-2015-2426","kev_date_added":"2022-03-28","published":"2015-07-20"},{"cvss_score":6.6,"headline":"Microsoft Windows Mount Manager Privilege Escalation","id":"CVE-2015-1769","kev_date_added":"2022-05-25","published":"2015-08-15"},{"cvss_score":10,"headline":"Windows Hard Link Elevation of Privilege Vulnerability","id":"CVE-2020-1467","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":9.9,"headline":"Windows TCP/IP Remote Code Execution Vulnerability","id":"CVE-2021-26424","kev_date_added":null,"published":"2021-08-12"},{"cvss_score":9.9,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2021-28476","kev_date_added":null,"published":"2021-05-11"},{"cvss_score":9.9,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2021-26867","kev_date_added":null,"published":"2021-03-11"},{"cvss_score":9.9,"headline":"Security feature bypass in Windows","id":"CVE-2019-1384","kev_date_added":null,"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Microsoft"]},"summary":"Man-in-the-middle attackers can bypass NTLM Message Integrity Check protection in Microsoft Windows, compromising authentication integrity.","url":"https://insights.sbomify.com/CVE-2019-1166/"}
