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-2016-5363 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- neutron (PyPI): affected all versions; fixed in 7.1.0, 8.1.0\n- neutron (PyPI): affected all versions; fixed in 7.1.0\n- neutron (PyPI): affected all versions; fixed in 7.1.0\n- neutron (PyPI): affected from 8.0.0; fixed in 8.1.0\n- neutron (PyPI): affected from 8.0.0; fixed in 8.1.0\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-2016-5363/ (Markdown: https://insights.sbomify.com/CVE-2016-5363/index.md)","id":"CVE-2016-5363","markdown":"https://insights.sbomify.com/CVE-2016-5363/index.md","name":"CVE-2016-5363","record":{"aliases":["DEBIAN-CVE-2016-5363","GHSA-9pp3-cvmq-9p22","PYSEC-2026-852"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Neutron","requires_auth":"none","summary":"Remote attackers can bypass MAC-spoofing protections in OpenStack Neutron to cause denial of service or intercept network traffic.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"neutron","vendor":"openstack"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-254","name":null}],"description":"The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended MAC-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via (1) a crafted DHCP discovery message or (2) crafted non-IP traffic.","ecosystems":["PyPI"],"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":"OpenStack Neutron Intended MAC-spoofing protection mechanism bypass","id":"CVE-2016-5363","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2016"},"n_packages":5,"n_references":9,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2016-5364"},"packages":[{"ecosystem":"PyPI","fixed":["7.1.0","8.1.0"],"introduced":["0","8.0.0"],"last_affected":[],"package":"neutron","purl":"pkg:pypi/neutron","source":"PYSEC-2026-852"},{"ecosystem":"PyPI","fixed":["7.1.0"],"introduced":["0"],"last_affected":[],"package":"neutron","purl":null,"source":"GHSA-9pp3-cvmq-9p22"},{"ecosystem":"PyPI","fixed":["7.1.0"],"introduced":["0"],"last_affected":[],"package":"neutron","purl":"pkg:pypi/neutron","source":"GHSA-9pp3-cvmq-9p22"},{"ecosystem":"PyPI","fixed":["8.1.0"],"introduced":["8.0.0"],"last_affected":[],"package":"neutron","purl":null,"source":"GHSA-9pp3-cvmq-9p22"},{"ecosystem":"PyPI","fixed":["8.1.0"],"introduced":["8.0.0"],"last_affected":[],"package":"neutron","purl":"pkg:pypi/neutron","source":"GHSA-9pp3-cvmq-9p22"}],"prev":{"headline":"OpenStack Neutron allows remote attackers to bypass an intended DHCP-spoofing protection mechanism","id":"CVE-2016-5362"},"products":["n/a"],"published":"2016-06-17","related":[{"cvss_score":9.1,"headline":"OpenStack Neutron vulnerable to hardware address impersonation","id":"CVE-2021-38598","kev_date_added":null,"published":"2021-08-23"},{"cvss_score":9.1,"headline":"OpenStack Neutron allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism","id":"CVE-2015-8914","kev_date_added":null,"published":"2016-06-17"},{"cvss_score":8.2,"headline":"OpenStack Neutron allows remote attackers to bypass an intended DHCP-spoofing protection mechanism","id":"CVE-2016-5362","kev_date_added":null,"published":"2016-06-17"},{"cvss_score":7.6,"headline":"Privilege escalation in n/a","id":"CVE-2014-3632","kev_date_added":null,"published":"2014-10-07"},{"cvss_score":7.1,"headline":"Openstack Neutron has Insufficient Verification of IPv6 addresses","id":"CVE-2021-20267","kev_date_added":null,"published":"2021-05-28"},{"cvss_score":6.5,"headline":"openstack-neutron uncontrolled resource consumption flaw","id":"CVE-2022-3277","kev_date_added":null,"published":"2023-03-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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 bypass MAC-spoofing protections in OpenStack Neutron to cause denial of service or intercept network traffic.","url":"https://insights.sbomify.com/CVE-2016-5363/"}
