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-2019-1338 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 7. 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-2019-1338/ (Markdown: https://insights.sbomify.com/CVE-2019-1338/index.md)","id":"CVE-2019-1338","markdown":"https://insights.sbomify.com/CVE-2019-1338/index.md","name":"CVE-2019-1338","record":{"aliases":["GHSA-qm7q-vxj7-9xg3"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Windows","requires_auth":"none","summary":"A man-in-the-middle attacker can bypass NTLMv2 protection in Microsoft Windows if LMv2 responses are sent, compromising authentication security.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_7","vendor":"microsoft"},{"product":"windows_server_2008","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":[],"description":"A security feature bypass vulnerability exists in Microsoft Windows when a man-in-the-middle attacker is able to successfully bypass the NTLMv2 protection if a client is also sending LMv2 responses, aka 'Windows NTLM Security Feature Bypass 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-2019-1338","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_7","products":["microsoft:windows_7","microsoft:windows_server_2008"],"type":"security_feature_bypass","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Windows","id":"CVE-2019-1339"},"packages":[],"prev":{"headline":"Information disclosure in Windows","id":"CVE-2019-1337"},"products":["Windows","Windows Server"],"published":"2019-10-10","related":[{"cvss_score":9.8,"headline":"Microsoft HTTP.sys Remote Code Execution","id":"CVE-2015-1635","kev_date_added":"2022-02-10","published":"2015-04-14"},{"cvss_score":8.8,"headline":"Microsoft Win32k Privilege Escalation","id":"CVE-2015-2360","kev_date_added":"2022-05-25","published":"2015-06-10"},{"cvss_score":8.8,"headline":"Microsoft Kerberos Key Distribution Center (KDC) Privilege Escalation","id":"CVE-2014-6324","kev_date_added":"2022-03-25","published":"2014-11-18"},{"cvss_score":8.8,"headline":"Microsoft Windows Object Linking \u0026 Embedding (OLE) Automation Array Remote Code Execution","id":"CVE-2014-6332","kev_date_added":"2022-03-25","published":"2014-11-11"},{"cvss_score":8.8,"headline":"Microsoft Windows Remote Code Execution","id":"CVE-2014-4148","kev_date_added":"2022-05-25","published":"2014-10-15"},{"cvss_score":8.8,"headline":"Microsoft Windows Group Policy Preferences Password Privilege Escalation","id":"CVE-2014-1812","kev_date_added":"2021-11-03","published":"2014-05-14"},{"cvss_score":8.8,"headline":"Microsoft Windows Out-of-Bounds Write","id":"CVE-2013-3918","kev_date_added":"2025-10-06","published":"2013-11-12"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Microsoft"]},"summary":"A man-in-the-middle attacker can bypass NTLMv2 protection in Microsoft Windows if LMv2 responses are sent, compromising authentication security.","url":"https://insights.sbomify.com/CVE-2019-1338/"}
