An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-7jmw-8259-q9jx in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/traefik/traefik (Go): affected all versions; no fix listed\n- github.com/traefik/traefik (Go): affected all versions; fixed in 2.11.4\n- github.com/traefik/traefik (Go): affected all versions; fixed in 2.11.4\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.4\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.4\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.4\n- github.com/traefik/traefik/v3 (Go): affected from 3.0.0-beta3; fixed in 3.0.2\n- github.com/traefik/traefik/v3 (Go): affected from 3.0.0-beta3; fixed in 3.0.2\n- github.com/traefik/traefik/v3 (Go): affected from 3.0.0-beta3; fixed in 3.0.2\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/GHSA-7jmw-8259-q9jx/ (Markdown: https://insights.sbomify.com/GHSA-7jmw-8259-q9jx/index.md)","id":"GHSA-7jmw-8259-q9jx","markdown":"https://insights.sbomify.com/GHSA-7jmw-8259-q9jx/index.md","name":"GHSA-7jmw-8259-q9jx","record":{"aliases":["GO-2024-2917"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Reverse proxy server","requires_auth":"none","summary":"Traefik incorrectly handles IPv4-mapped IPv6 addresses, allowing attackers to bypass IP-based access controls or security filters.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\n\nThere is a vulnerability in [Go managing various Is methods (IsPrivate, IsLoopback, etc) for IPv4-mapped IPv6 addresses](https://groups.google.com/g/golang-announce/c/XbxouI9gY7k/m/TuoGEhxIEwAJ).\n\nThey didn't work as expected returning false for addresses which would return true in their traditional IPv4 forms.\n\n### References\n\n- [CVE-2024-24790](https://www.cve.org/CVERecord?id=CVE-2024-24790)\n\n### Patches\n\n- https://github.com/traefik/traefik/releases/tag/v2.11.4\n- https://github.com/traefik/traefik/releases/tag/v3.0.2\n\n### Workarounds\n\nNo workaround.\n\n### For more information\n\nIf you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).","ecosystems":["Go"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Traefik has unexpected behavior with IPv4-mapped IPv6 addresses","id":"GHSA-7jmw-8259-q9jx","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"security_feature_bypass","year":"2024"},"n_packages":9,"n_references":null,"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","source":"GO-2024-2917"},{"ecosystem":"Go","fixed":["2.11.4"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik","purl":null,"source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["2.11.4"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["2.11.4"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":null,"source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["2.11.4"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["2.11.4"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","source":"GO-2024-2917"},{"ecosystem":"Go","fixed":["3.0.2"],"introduced":["3.0.0-beta3"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":null,"source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["3.0.2"],"introduced":["3.0.0-beta3"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GHSA-7jmw-8259-q9jx"},{"ecosystem":"Go","fixed":["3.0.2"],"introduced":["3.0.0-beta3"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GO-2024-2917"}],"products":null,"published":"2024-06-11","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Traefik incorrectly handles IPv4-mapped IPv6 addresses, allowing attackers to bypass IP-based access controls or security filters.","url":"https://insights.sbomify.com/GHSA-7jmw-8259-q9jx/"}
