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-2015-7871 exists.\n\nAffected product: Debian Debian Linux. 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-2015-7871/ (Markdown: https://insights.sbomify.com/CVE-2015-7871/index.md)","id":"CVE-2015-7871","markdown":"https://insights.sbomify.com/CVE-2015-7871/index.md","name":"CVE-2015-7871","record":{"aliases":["DEBIAN-CVE-2015-7871","GHSA-mxc3-mjx4-gjc9","UBUNTU-CVE-2015-7871"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NTP daemon","requires_auth":"none","summary":"Remote attackers can bypass authentication in the NTP daemon by sending crafted Crypto-NAK packets, compromising time synchronization integrity.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"data_ontap","vendor":"netapp"},{"product":"oncommand_balance","vendor":"netapp"},{"product":"oncommand_performance_manager","vendor":"netapp"},{"product":"oncommand_unified_manager","vendor":"netapp"},{"product":"ntp","vendor":"ntp"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":null,"kind":"metasploit","ref":"auxiliary/scanner/ntp/ntp_nak_to_the_future","stars":null,"title":"NTP \"NAK to the Future\""}],"tier":"weaponised"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2015-7871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","netapp:clustered_data_ontap","netapp:oncommand_balance","netapp:oncommand_performance_manager","netapp:oncommand_unified_manager","ntp:ntp"],"type":"auth_bypass","year":"2015"},"n_packages":0,"n_references":10,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-7872"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2015-7869"},"products":["n/a"],"published":"2017-08-07","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can bypass authentication in the NTP daemon by sending crafted Crypto-NAK packets, compromising time synchronization integrity.","url":"https://insights.sbomify.com/CVE-2015-7871/"}
