An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-21342 and fix it if it is affected.\n\nWhat it is: CVE-2024-21342 is a high-severity denial of service vulnerability in Microsoft Windows 11 22h2, published on 13 Feb 2024. 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-2024-21342 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 11 22h2. 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-2024-21342/ (Markdown: https://insights.sbomify.com/CVE-2024-21342/index.md)","id":"CVE-2024-21342","markdown":"https://insights.sbomify.com/CVE-2024-21342/index.md","name":"CVE-2024-21342","record":{"aliases":["GHSA-95rw-m3jj-r8jm"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows DNS Client","requires_auth":"none","summary":"An attacker can cause a denial of service in the Windows DNS Client, affecting Windows 11 and Server 2022 systems.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_11_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_server_2022_23h2","vendor":"microsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Windows DNS Client Denial of Service 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":"Windows DNS Client Denial of Service Vulnerability","id":"CVE-2024-21342","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_11_22h2","products":["microsoft:windows_11_22h2","microsoft:windows_11_23h2","microsoft:windows_server_2022_23h2"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Network Address Translation (NAT) Denial of Service Vulnerability","id":"CVE-2024-21343"},"packages":[],"prev":{"headline":"Windows Kernel Remote Code Execution Vulnerability","id":"CVE-2024-21341"},"products":["Windows 11 Version 23H2","Windows 11 version 22H2","Windows 11 version 22H3","Windows Server 2022, 23H2 Edition (Server Core installation)"],"published":"2024-02-13","related":[{"cvss_score":8.8,"headline":"Windows Hyper-V Remote Code Execution Vulnerability","id":"CVE-2024-49117","kev_date_added":null,"published":"2024-12-10"},{"cvss_score":8.8,"headline":"Windows OLE Remote Code Execution Vulnerability","id":"CVE-2024-21435","kev_date_added":null,"published":"2024-03-12"},{"cvss_score":8.4,"headline":"Windows Subsystem for Linux (WSL2) Kernel Remote Code Execution Vulnerability","id":"CVE-2025-24084","kev_date_added":null,"published":"2025-03-11"},{"cvss_score":8.1,"headline":"Remote Desktop Spoofing Vulnerability","id":"CVE-2025-33054","kev_date_added":null,"published":"2025-07-08"},{"cvss_score":8.1,"headline":"Windows Schannel Remote Code Execution Vulnerability","id":"CVE-2025-29828","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":8.1,"headline":"Microsoft Windows VMSwitch Elevation of Privilege Vulnerability","id":"CVE-2024-43625","kev_date_added":null,"published":"2024-11-12"},{"cvss_score":8,"headline":"Secure Boot Security Feature Bypass Vulnerability","id":"CVE-2024-37978","kev_date_added":null,"published":"2024-07-09"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["Microsoft"]},"summary":"An attacker can cause a denial of service in the Windows DNS Client, affecting Windows 11 and Server 2022 systems.","url":"https://insights.sbomify.com/CVE-2024-21342/"}
