{"id":"CVE-2022-24790","summary":"HTTP Request Smuggling in puma","details":"Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends. This would allow requests to be smuggled via the front-end proxy to Puma. The vulnerability has been fixed in 5.6.4 and 4.3.12. Users are advised to upgrade as soon as possible. Workaround: when deploying a proxy in front of Puma, turning on any and all functionality to make sure that the request matches the RFC7230 standard.","aliases":["GHSA-h99w-9q5r-gjq9"],"modified":"2026-04-10T04:45:32.394239Z","published":"2022-03-30T21:50:09Z","related":["SUSE-SU-2022:3338-1","SUSE-SU-2022:3339-1","SUSE-SU-2022:3571-1","openSUSE-SU-2024:12032-1","openSUSE-SU-2024:12592-1","openSUSE-SU-2024:13166-1","openSUSE-SU-2024:13721-1"],"database_specific":{"cwe_ids":["CWE-444"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/24xxx/CVE-2022-24790.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/24xxx/CVE-2022-24790.json"},{"type":"ADVISORY","url":"https://github.com/puma/puma/security/advisories/GHSA-h99w-9q5r-gjq9"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F6YWGIIKL7KKTS3ZOAYMYPC7D6WQ5OA5/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L7NESIBFCNSR3XH7LXDPKVMSUBNUB43G/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TUBFJ44NCKJ34LECZRAP4N5VL6USJSIB/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-24790"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202208-28"},{"type":"ADVISORY","url":"https://www.debian.org/security/2022/dsa-5146"},{"type":"FIX","url":"https://github.com/puma/puma/commit/5bb7d202e24dec00a898dca4aa11db391d7787a5"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2022/08/msg00015.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/puma/puma","events":[{"introduced":"0"},{"fixed":"831d8a8be0da8d2dea7b47d683cfea66a0b0b47f"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"4.3.12"}]}},{"type":"GIT","repo":"https://github.com/puma/puma","events":[{"introduced":"13e18e8078c800adfc52af687acc1d8de5f3988d"},{"fixed":"7add06a280c305eeb32a98c4fca4b34521cbf12f"}],"database_specific":{"versions":[{"introduced":"5.0.0"},{"fixed":"5.6.4"}]}}],"versions":["v1.1.0","v1.1.1","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v1.3.1","v1.4.0","v1.5.0","v2.0.0","v2.0.0.b2","v2.0.0.b3","v2.0.0.b4","v2.0.0.b5","v2.0.0.b6","v2.0.0.b7","v2.0.1","v2.1.0","v2.1.1","v2.10.0","v2.10.1","v2.10.2","v2.11.0","v2.11.2","v2.11.3","v2.12.0","v2.12.1","v2.12.2","v2.12.3","v2.13.0","v2.13.1","v2.13.2","v2.13.3","v2.13.4","v2.14.0","v2.15.0","v2.15.1","v2.15.2","v2.15.3","v2.16.0","v2.2.0","v2.2.1","v2.2.2","v2.3.0","v2.3.1","v2.3.2","v2.4.0","v2.4.1","v2.5.0","v2.5.1","v2.6.0","v2.7.0","v2.7.1","v2.8.1","v2.8.2","v2.9.0","v2.9.1","v2.9.2","v3.0.0","v3.0.0.rc1","v3.0.1","v3.0.2","v3.1.0","v3.1.1","v3.10.0","v3.11.0","v3.11.1","v3.11.2","v3.11.3","v3.11.4","v3.12.0","v3.2.0","v3.3.0","v3.4.0","v3.5.0","v3.5.1","v3.5.2","v3.6.0","v3.7.1","v3.8.0","v3.9.0","v3.9.1","v4.0.0","v4.0.1","v4.1.0","v4.2.0","v4.2.1","v4.3.0","v4.3.1","v4.3.10","v4.3.11","v4.3.2","v4.3.3","v4.3.4","v4.3.5","v4.3.6","v4.3.7","v4.3.8","v4.3.9","v5.0.0","v5.0.1","v5.0.2","v5.0.3","v5.1.0","v5.2.0","v5.2.1","v5.2.2","v5.3.0","v5.3.1","v5.3.2","v5.4.0","v5.5.0","v5.5.1","v5.5.2","v5.6.0","v5.6.1","v5.6.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-24790.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
