It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-7427 in the wild and no public exploit code.\n\nAffected product: Ntp Ntp. 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-2016-7427/ (Markdown: https://insights.sbomify.com/CVE-2016-7427/index.md)","id":"CVE-2016-7427","markdown":"https://insights.sbomify.com/CVE-2016-7427/index.md","name":"CVE-2016-7427","record":{"aliases":["DEBIAN-CVE-2016-7427","GHSA-mr7q-6qv6-frx4","UBUNTU-CVE-2016-7427"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"NTP daemon","requires_auth":"none","summary":"Remote attackers can cause denial of service in NTP broadcast mode by sending crafted packets, affecting systems using this specific configuration.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ntp","vendor":"ntp"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2016-7427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ntp:ntp","products":["ntp:ntp"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":12,"next":{"headline":"Denial of service in n/a","id":"CVE-2016-7428"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2016-7426"},"products":["n/a"],"published":"2017-01-13","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-12327","kev_date_added":null,"published":"2018-06-20"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-6460","kev_date_added":null,"published":"2017-03-27"},{"cvss_score":8.1,"headline":"Other in n/a","id":"CVE-2019-11331","kev_date_added":null,"published":"2019-04-18"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-6451","kev_date_added":null,"published":"2017-03-27"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-6452","kev_date_added":null,"published":"2017-03-27"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2017-6462","kev_date_added":null,"published":"2017-03-27"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2015-7978","kev_date_added":null,"published":"2017-01-30"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service in NTP broadcast mode by sending crafted packets, affecting systems using this specific configuration.","url":"https://insights.sbomify.com/CVE-2016-7427/"}
