The result of the regression was that invalid Transfer-Encoding headers were incorrectly processed leading to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.","affected":[{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.98"},{"fixed":"7.0.100"}]}],"versions":["7.0.99"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}},{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.5.48"},{"fixed":"8.5.51"}]}],"versions":["8.5.49","8.5.50"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}},{"package":{"name":"org.apache.tomcat.embed:tomcat-embed-core","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.28"},{"fixed":"9.0.31"}]}],"versions":["9.0.29","9.0.30"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.98"},{"fixed":"7.0.100"}]}],"versions":["7.0.99"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.5.48"},{"fixed":"8.5.51"}]}],"versions":["8.5.49","8.5.50"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.28"},{"fixed":"9.0.31"}]}],"versions":["9.0.29","9.0.30"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/02/GHSA-767j-jfh2-jvrc/GHSA-767j-jfh2-jvrc.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-17569"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r7bc994c965a34876bd94d5ff15b4e1e30b6220a15eb9b47c81915b78@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r88def002c5c78534674ca67472e035099fbe088813d50062094a1390%40%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc31cbabb46cdc58bbdd8519a8f64b6236b2635a3922bbeba0f0e3743@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/03/msg00006.html"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20200327-0005"},{"type":"WEB","url":"https://www.debian.org/security/2020/dsa-4673"},{"type":"WEB","url":"https://www.debian.org/security/2020/dsa-4680"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujan2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujul2020.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2020.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00025.html"}],"database_specific":{"cwe_ids":["CWE-444"],"github_reviewed":true,"github_reviewed_at":"2020-02-25T16:19:11Z","nvd_published_at":"2020-02-24T22:15:00Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
