{"id":"CVE-2017-5647","aliases":["GHSA-3gv7-3h64-78cm"],"url":"https://o3.security/vulnerability/CVE-2017-5647","summary":"Exposure of Sensitive Information to an Unauthorized Actor in Apache Tomcat","details":"A bug in the handling of the pipelined requests in Apache Tomcat 9.0.0.M1 to 9.0.0.M18, 8.5.0 to 8.5.12, 8.0.0.RC1 to 8.0.42, 7.0.0 to 7.0.76, and 6.0.0 to 6.0.52, when send file was used, results in the pipelined request being lost when send file processing of the previous request completed. This could result in responses appearing to be sent for the wrong request. For example, a user agent that sent requests A, B and C could see the correct response for request A, the response for request C for request B and no response for request C.","published":"2017-04-17T16:59:00.320Z","modified":"2026-07-08T05:49:47.659215245Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.1684,"percentile":0.96803,"asOf":"2026-08-22"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"9.0.0.M19"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"8.5.13"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"8.0.43"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"7.0.77"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"6.0.53"}],"fix":null,"references":[{"type":"WEB","url":"http://www.arubanetworks.com/assets/alert/HPESBHF03730.txt"},{"type":"WEB","url":"http://www.securitytracker.com/id/1038218"},{"type":"WEB","url":"https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03730en_us"},{"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/37220405a377c0182d2afdbc36461c4783b2930fbeae3a17f1333113%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/388a323769f1dff84c9ec905455aa73fbcb20338e3c7eb131457f708%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/39ae1f0bd5867c15755a6f959b271ade1aea04ccdc3b2e639dcd903b%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/3d19773b4cf0377db62d1e9328bf9160bf1819f04f988315086931d7%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/5796678c5a773c6f3ff57c178ac247d85ceca0dee9190ba48171451a%40%3Cusers.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/6af47120905aa7d8fe12f42e8ff2284fb338ba141d3b77b8c7cb61b3%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/845312a10aabbe2c499fca94003881d2c79fc993d85f34c1f5c77424%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/b84ad1258a89de5c9c853c7f2d3ad77e5b8b2930be9e132d5cef6b95%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/b8a1bf18155b552dcf9a928ba808cbadad84c236d85eab3033662cfb%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/r03c597a64de790ba42c167efacfa23300c3d6c9fe589ab87fe02859c%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":"WEB","url":"https://lists.apache.org/thread.html/r587e50b86c1a96ee301f751d50294072d142fd6dc08a8987ae9f3a9b%40%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9136ff5b13e4f1941360b5a309efee2c114a14855578c3a2cbe5d19c%40%3Cdev.tomcat.apache.org%3E"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3842"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3843"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:1801"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:1802"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2493"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2494"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3080"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3081"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201705-09"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180614-0001/"},{"type":"ADVISORY","url":"https://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html"}],"provenance":{"sources":["OSV.dev","FIRST.org
