{"id":"GHSA-4vww-mc66-62m6","summary":"HTTP Request Smuggling in Apache Tomcat","details":"Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.","aliases":["BIT-tomcat-2021-33037","CVE-2021-33037"],"modified":"2024-03-11T18:15:50.231095Z","published":"2021-08-13T15:21:14Z","database_specific":{"nvd_published_at":"2021-07-12T15:15:00Z","cwe_ids":["CWE-444"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2021-07-13T19:38:16Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-33037"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/05f9e8b00f5d9251fcd3c95dcfd6cf84177f46c8"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/19d11556d0db99df291df33605f137976d152475"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/3202703e6d635e39b74262e81f0cb4bcbe2170dc"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/45d70a86a901cbd534f8f570bed2aec9f7f7b88e"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/506134f957a4be2c5b4a9334f7b3435fc954dbc1"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/8874fa02e9b36baa9ca6b226c0882c0190ca5a02"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/a2c3dc4c96168743ac0bab613709a5bbdaec41d0"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/da0e7cb093cf68b052d9175e469dbd0464441b0b"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/eee0d024c1b3171560c92eaba79dd6eb8eb11bcd"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202208-34"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20210827-0007"},{"type":"WEB","url":"https://tomcat.apache.org/security-10.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-8.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-9.html"},{"type":"WEB","url":"https://www.debian.org/security/2021/dsa-4952"},{"type":"WEB","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuoct2021.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2021/08/msg00009.html"},{"type":"WEB","url":"https://lists.apache.org/thread/kovg1bft77xo34ksrcskh5nl50p69962"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf1b54fd3f52f998ca4829159a88cc4c23d6cef5c6447d00948e75c97@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re01e7e93154e8bdf78a11a23f9686427bd3d51fc6e12c508645567b7@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd0dfea39829bc0606c936a16f6fca338127c86c0a1083970b45ac8d2@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc6ef52453bb996a98cb45442871a1db56b7c349939e45d829bf9ae37@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r612a79269b0d5e5780c62dfd34286a8037232fec0bc6f1a7e60c9381%40%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r40f921575aee8d7d34e53182f862c45cbb8f3d898c9d4e865c2ec262@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r290aee55b72811fd19e75ac80f6143716c079170c5671b96932ed44b@%3Ccommits.tomee.apache.org%3E"},{"type":"WEB","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10366"},{"type":"PACKAGE","url":"https://github.com/apache/tomcat"}],"affected":[{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.0.0-M1"},{"fixed":"10.0.7"}]}],"versions":["10.0.0","10.0.0-M1","10.0.0-M10","10.0.0-M3","10.0.0-M4","10.0.0-M5","10.0.0-M6","10.0.0-M7","10.0.0-M8","10.0.0-M9","10.0.2","10.0.4","10.0.5","10.0.6"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-4vww-mc66-62m6/GHSA-4vww-mc66-62m6.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0-M1"},{"fixed":"9.0.48"}]}],"versions":["9.0.0.M1","9.0.0.M10","9.0.0.M11","9.0.0.M13","9.0.0.M15","9.0.0.M17","9.0.0.M18","9.0.0.M19","9.0.0.M20","9.0.0.M21","9.0.0.M22","9.0.0.M25","9.0.0.M26","9.0.0.M27","9.0.0.M3","9.0.0.M4","9.0.0.M6","9.0.0.M8","9.0.0.M9","9.0.1","9.0.10","9.0.11","9.0.12","9.0.13","9.0.14","9.0.16","9.0.17","9.0.19","9.0.2","9.0.20","9.0.21","9.0.22","9.0.24","9.0.26","9.0.27","9.0.29","9.0.30","9.0.31","9.0.33","9.0.34","9.0.35","9.0.36","9.0.37","9.0.38","9.0.39","9.0.4","9.0.40","9.0.41","9.0.43","9.0.44","9.0.45","9.0.46","9.0.5","9.0.6","9.0.7","9.0.8"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-4vww-mc66-62m6/GHSA-4vww-mc66-62m6.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.ap
