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-2023-4012 in the wild and no public exploit code.\n\nAffected product: ntpsec. 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-2023-4012/ (Markdown: https://insights.sbomify.com/CVE-2023-4012/index.md)","id":"CVE-2023-4012","markdown":"https://insights.sbomify.com/CVE-2023-4012/index.md","name":"CVE-2023-4012","record":{"aliases":["DEBIAN-CVE-2023-4012","DSA-5466-1","GHSA-777h-w3h9-x4qv","UBUNTU-CVE-2023-4012","openSUSE-SU-2024:13463-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NTP time server","requires_auth":"none","summary":"An attacker can crash the NTPsec server by sending NTS-enabled requests to a non-NTS server, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"ntpsec","vendor":"ntpsec"}],"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","version":"3.1"},"cwes":[{"id":"CWE-372","name":"Incomplete Internal State Distinction"}],"description":"ntpd will crash if the server is not NTS-enabled (no certificate) and it receives an NTS-enabled client request (mode 3).","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":"Incomplete Internal State Distinction in ntpsec","id":"CVE-2023-4012","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"GDPR Cookie Compliance \u003c 4.12.5 - License Update/Deactivation via CSRF","id":"CVE-2023-4013"},"packages":[],"prev":{"headline":"Allocation of Resources Without Limits or Throttling in GitLab","id":"CVE-2023-4011"},"products":["ntpsec"],"published":"2023-08-07","related":[{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2019-6443","kev_date_added":null,"published":"2019-01-16"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2019-6444","kev_date_added":null,"published":"2019-01-16"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2019-6442","kev_date_added":null,"published":"2019-01-16"},{"cvss_score":6.5,"headline":"Null dereference in n/a","id":"CVE-2019-6445","kev_date_added":null,"published":"2019-01-16"}],"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":"2026-06-22","vendors":["NTPsec"]},"summary":"An attacker can crash the NTPsec server by sending NTS-enabled requests to a non-NTS server, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2023-4012/"}
