It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-28312 and fix it if it is affected.\n\nWhat it is: CVE-2021-28312 is a low-severity denial of service vulnerability in Microsoft Windows 10, published on 13 Apr 2021. 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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-28312 exists.\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-2021-28312/ (Markdown: https://insights.sbomify.com/CVE-2021-28312/index.md)","id":"CVE-2021-28312","markdown":"https://insights.sbomify.com/CVE-2021-28312/index.md","name":"CVE-2021-28312","record":{"aliases":["GHSA-h4mx-7r9h-mq8f"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows NTFS","requires_auth":"none","summary":"An attacker can cause a denial of service in Windows NTFS, affecting system availability.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:F/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"Windows NTFS Denial of Service Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-05-07","github_poc":1,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-05-07T20:16:22Z","kind":"github_poc","ref":"https://github.com/shubham0d/CVE-2021-28312","stars":5,"title":"POC and description for CVE-2021-28312"}],"tier":"weaponised"},"has_fix":null,"headline":"Windows NTFS Denial of Service Vulnerability","id":"CVE-2021-28312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_10","products":["microsoft:windows_10","microsoft:windows_server_2016","microsoft:windows_server_2019"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Diagnostics Hub Standard Collector Service Elevation of Privilege Vulnerability","id":"CVE-2021-28313"},"packages":[],"prev":{"headline":"Windows Application Compatibility Cache Denial of Service Vulnerability","id":"CVE-2021-28311"},"products":["Windows 10 Version 1809","Windows 10 Version 1909","Windows 10 Version 2004","Windows 10 Version 20H2","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server version 2004","Windows Server version 20H2","Windows Server, version 1909 (Server Core installation)"],"published":"2021-04-13","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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-01","vendors":["Microsoft"]},"summary":"An attacker can cause a denial of service in Windows NTFS, affecting system availability.","url":"https://insights.sbomify.com/CVE-2021-28312/"}
