{"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":"2026-05-28T03:55:10.873488834Z","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":"13e18e8078c800adfc52af687acc1d8de5f3988d"},{"fixed":"7add06a280c305eeb32a98c4fca4b34521cbf12f"}]}],"versions":["v5.6.2","v5.6.1","v5.6.0","v5.5.2","v5.5.1","v5.5.0","v5.4.0","v5.3.2","v5.3.1","v5.3.0","v5.2.2","v5.2.1","v5.2.0","v5.1.0","v5.0.3","v5.0.2","v5.0.1","v5.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-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"}]}
