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-2019-11331 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-2019-11331/ (Markdown: https://insights.sbomify.com/CVE-2019-11331/index.md)","id":"CVE-2019-11331","markdown":"https://insights.sbomify.com/CVE-2019-11331/index.md","name":"CVE-2019-11331","record":{"aliases":["GHSA-2c4g-qfqp-42mh"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NTP protocol","requires_auth":"none","summary":"The NTP protocol's use of a fixed port facilitates off-path attacks, allowing remote attackers to bypass security controls.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ntp","vendor":"ntp"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"Network Time Protocol (NTP), as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks.","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":"Other in n/a","id":"CVE-2019-11331","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ntp:ntp","products":["ntp:ntp"],"type":"other","year":"2019"},"n_packages":0,"n_references":4,"next":{"headline":"Business logic in n/a","id":"CVE-2019-11332"},"packages":[],"prev":{"headline":"Incorrect Permission Assignment for Critical Resource in Singularity","id":"CVE-2019-11328"},"products":["n/a"],"published":"2019-04-18","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":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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"The NTP protocol's use of a fixed port facilitates off-path attacks, allowing remote attackers to bypass security controls.","url":"https://insights.sbomify.com/CVE-2019-11331/"}
