An HTTP/1 style request line (i.e. method space URI space version) that declares a version of HTTP/0.9 was accepted and treated as a 0.9 request. If deployed behind an intermediary that also accepted and passed through the 0.9 version (but did not act on it), then the response sent could be interpreted by the intermediary as HTTP/1 headers. This could be used to poison the cache if the server allowed the origin client to generate arbitrary content in the response.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-444"],"references":["http://www.securitytracker.com/id/1041194","https://bugs.eclipse.org/bugs/show_bug.cgi?id=535667","https://lists.apache.org/thread.html/053d9ce4d579b02203db18545fee5e33f35f2932885459b74d1e4272%40%3Cissues.activemq.apache.org%3E","https://lists.apache.org/thread.html/708d94141126eac03011144a971a6411fcac16d9c248d1d535a39451%40%3Csolr-user.lucene.apache.org%3E","https://lists.apache.org/thread.html/9317fd092b257a0815434b116a8af8daea6e920b6673f4fd5583d5fe%40%3Ccommits.druid.apache.org%3E"],"products":["debian:debian_linux","eclipse:jetty"],"source":"nvd","synced_at":"2026-10-19T20:51:47.459859389+00:00"},"epss":{"cve":"CVE-2017-7656","score":0.0633,"percentile":0.93626,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-84q7-p226-4x5w","url":"https://osv.dev/vulnerability/GHSA-84q7-p226-4x5w","summary":"Jetty vulnerable to cache poisoning due to inconsistent HTTP request handling (HTTP Request Smuggling)","modified":"2024-02-16T08:17:36.036350Z","packages":[{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-server","purl":"pkg:maven/org.eclipse.jetty/jetty-server","ranges":["<9.3.24.v20180605"],"fixed":["9.3.24.v20180605"]},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-server","purl":"pkg:maven/org.eclipse.jetty/jetty-server","ranges":[">=9.4.0 <9.4.11.v20180605"],"fixed":["9.4.11.v20180605"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
