{"id":"CVE-2017-5651","aliases":["GHSA-9hg2-395j-83rm"],"url":"https://o3.security/vulnerability/CVE-2017-5651","summary":"Expected Behavior Violation in Apache Tomcat","details":"In Apache Tomcat 9.0.0.M1 to 9.0.0.M18 and 8.5.0 to 8.5.12, the refactoring of the HTTP connectors introduced a regression in the send file processing. If the send file processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could result in the same Processor being used for multiple requests which in turn could lead to unexpected errors and/or response mix-up.","published":"2017-04-17T16:59:00.477Z","modified":"2026-10-24T10:30:47.275151818Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","fixedVersion":"9.0.0.M19"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","fixedVersion":"8.5.13"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"9.0.0.M19"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"8.5.13"}],"fix":{"url":"https://github.com/apache/tomcat/commit/494429ca210641b6b7affe89a2b0a6c0ff70109b","label":"apache/tomcat@494429c"},"references":[{"type":"WEB","url":"http://www.securitytracker.com/id/1038219"},{"type":"WEB","url":"https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/5c0e00fd31efc11e147bf99d0f03c00a734447d3b131ab0818644cdb%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/6694538826b87522fb723d2dcedd537e14ebe0a381d92e5525a531d8%40%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/6af47120905aa7d8fe12f42e8ff2284fb338ba141d3b77b8c7cb61b3%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/88855876c33f2f9c532ffb75bfee570ccf0b17ffa77493745af9a17a%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/b5e3f51d28cd5d9b1809f56594f2cf63dcd6a90429e16ea9f83bbedc%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/eb6efa8d59c45a7a9eff94c4b925467d3b3fec8ba7697f3daa314b04%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r3bbb800a816d0a51eccc5a228c58736960a9fffafa581a225834d97d%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r48c1444845fe15a823e1374674bfc297d5008a5453788099ea14caf0%40%3Cdev.tomcat.apache.org%3E"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/97544"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201705-09"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180614-0001/"},{"type":"FIX","url":"https://bz.apache.org/bugzilla/show_bug.cgi?id=60918"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-5651"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/494429ca210641b6b7affe89a2b0a6c0ff70109b"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/9233d9d6a018be4415d4d7d6cb4fe01176adf1a8"},{"type":"WEB","url":"https://web.archive.org/web/20170420113605/http://www.securitytracker.com/id/1038219"},{"type":"WEB","url":"https://web.archive.org/web/20170417124228/http://www.securityfocus.com/bid/97544"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20180614-0001"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r48c1444845fe15a823e1374674bfc297d5008a5453788099ea14caf0@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r3bbb800a816d0a51eccc5a228c58736960a9fffafa581a225834d97d@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/eb6efa8d59c45a7a9eff94c4b925467d3b3fec8ba7697f3daa314b04@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/b5e3f51d28cd5d9b1809f56594f2cf63dcd6a90429e16ea9f83bbedc@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/88855876c33f2f9c532ffb75bfee570ccf0b17ffa77493745af9a17a@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/6af47120905aa7d8fe12f42e8ff2284fb338ba141d3b77b8c7cb61b3@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/6694538826b87522fb723d2dcedd537e14ebe0a381d92e5525a531d8@%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/5c0e00fd31efc11e147bf99d0f03c00a734447d3b131ab0818644cdb@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://github.com/search?q=repo%3Aapache%2Ftomcat+apache.coyote+path%3A%2F%5Eres%5C%2Fbnd%5C%2F%2F&type=code"},{"type":"PACKAGE","url":"https://github.com/apache/tomcat"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-24T10:30:47.275151818Z"}}
