{"id":"GHSA-8928-2fgm-6x9x","summary":"HTTP Request Smuggling in actix-http","details":"Affected versions of this crate did not properly detect invalid requests that could allow HTTP/1 request smuggling (HRS) attacks when running alongside a vulnerable front-end proxy server. This can result in leaked internal and/or user data, including credentials, when the front-end proxy is also vulnerable.\n\nPopular front-end proxies and load balancers already mitigate HRS attacks so it is recommended that they are also kept up to date; check your specific set up. You should upgrade even if the front-end proxy receives exclusively HTTP/2 traffic and connects to the back-end using HTTP/1; several downgrade attacks are known that can also expose HRS vulnerabilities.","aliases":["CVE-2021-38512","RUSTSEC-2021-0081"],"modified":"2023-11-08T04:06:27.940101Z","published":"2021-08-25T20:58:21Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-18T20:13:40Z","nvd_published_at":"2021-08-10T23:15:00Z","cwe_ids":["CWE-444"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-38512"},{"type":"WEB","url":"https://github.com/actix/actix-web/pull/2363"},{"type":"WEB","url":"https://github.com/actix/actix-web/commit/e965d8298f421e9c89fe98b1300b8361e948c324"},{"type":"PACKAGE","url":"https://github.com/actix/actix-web"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/67URRW4K47SR6LNQB4YALPLGGQMQK7HO"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/actix-http/RUSTSEC-2021-0081.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2021-0081.html"}],"affected":[{"package":{"name":"actix-http","ecosystem":"crates.io","purl":"pkg:cargo/actix-http"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.2.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-8928-2fgm-6x9x/GHSA-8928-2fgm-6x9x.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
