An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-7434 exists.\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-2016-7434/ (Markdown: https://insights.sbomify.com/CVE-2016-7434/index.md)","id":"CVE-2016-7434","markdown":"https://insights.sbomify.com/CVE-2016-7434/index.md","name":"CVE-2016-7434","record":{"aliases":["DEBIAN-CVE-2016-7434","GHSA-qf57-pg9f-mrmv","UBUNTU-CVE-2016-7434"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NTP server","requires_auth":"none","summary":"Remote attackers can crash the NTP server by sending a crafted mrulist query, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hpux-ntp","vendor":"hpe"},{"product":"ntp","vendor":"ntp"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-11-21","github_poc":3,"max_poc_stars":25,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-11-22T19:42:17Z","kind":"github_poc","ref":"https://github.com/opsxcq/exploit-CVE-2016-7434","stars":25,"title":"NTPD remote DOS exploit and vulnerable container"},{"date":"2016-11-27T01:14:20Z","kind":"github_poc","ref":"https://github.com/shekkbuilder/CVE-2016-7434","stars":2,"title":null},{"date":"2016-11-21","kind":"exploitdb","ref":"40806","stars":null,"title":"NTP 4.2.8p8 - Denial of Service"},{"date":"2019-01-06T22:15:24Z","kind":"github_poc","ref":"https://github.com/cved-sources/cve-2016-7434","stars":0,"title":"cve-2016-7434"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2016-7434","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":10,"next":{"headline":"Command injection in n/a","id":"CVE-2016-7435"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2016-7433"},"products":["n/a"],"published":"2017-01-13","related":[{"cvss_score":5.3,"headline":"Business logic in n/a","id":"CVE-2018-7170","kev_date_added":null,"published":"2018-03-06"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash the NTP server by sending a crafted mrulist query, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2016-7434/"}
