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-2025-23019 in the wild and no public exploit code.\n\nAffected product: IETF IPv6. 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-2025-23019/ (Markdown: https://insights.sbomify.com/CVE-2025-23019/index.md)","id":"CVE-2025-23019","markdown":"https://insights.sbomify.com/CVE-2025-23019/index.md","name":"CVE-2025-23019","record":{"aliases":["GHSA-qpjx-9hp9-85gm"],"analysis":{"component_type":"operating_system","fix_type":"configuration_change","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"IPv6 networking stack","requires_auth":"none","summary":"Attackers can spoof and route traffic via exposed interfaces if IPv6-in-IPv4 tunneling is enabled, bypassing network security controls.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ipv6","vendor":"ietf"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"}],"description":"IPv6-in-IPv4 tunneling (RFC 4213) allows an attacker to spoof and route traffic via an exposed network interface.","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 IPv6","id":"CVE-2025-23019","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Kwik hash collision vulnerability","id":"CVE-2025-23020"},"packages":[],"prev":{"headline":"Security feature bypass in IPv6","id":"CVE-2025-23018"},"products":["IPv6"],"published":"2025-01-14","related":[{"cvss_score":8.6,"headline":"Denial of service in n/a","id":"CVE-2016-10142","kev_date_added":null,"published":"2017-01-14"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2007-2242","kev_date_added":null,"published":"2007-04-25"},{"cvss_score":5.4,"headline":"Security feature bypass in IPv6","id":"CVE-2025-23018","kev_date_added":null,"published":"2025-01-14"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["IETF"]},"summary":"Attackers can spoof and route traffic via exposed interfaces if IPv6-in-IPv4 tunneling is enabled, bypassing network security controls.","url":"https://insights.sbomify.com/CVE-2025-23019/"}
