This JSP could then be requested and any code it contained would be executed by the server.","published":"2017-10-04T01:29:02.120Z","modified":"2026-08-27T11:47:37.051923267Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.99988,"percentile":0.99984,"asOf":"2026-08-27"},"cisaKev":{"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":false},"exploitsKnown":14,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","fixedVersion":"9.0.1"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","fixedVersion":"8.5.23"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","fixedVersion":"8.0.47"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-catalina","fixedVersion":"7.0.82"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"9.0.1"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"8.5.23"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"8.0.47"},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","fixedVersion":"7.0.82"}],"fix":null,"references":[{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2017-12617"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/100954"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1039552"},{"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://access.redhat.com/errata/RHSA-2017:3113"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3114"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0268"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0269"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0270"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0271"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0275"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0465"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0466"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:2939"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2017/11/msg00009.html"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20171018-0002/"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180117-0002/"},{"type":"ADVISORY","url":"https://support.f5.com/csp/article/K53173544"},{"type":"ADVISORY","url":"https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03812en_us"},{"type":"ADVISORY","url":"https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03828en_us"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3665-1/"},{"type":"REPORT","url":"https://lists.apache.org/thread.html/3fd341a604c4e9eab39e7eaabbbac39c30101a022acc11dd09d7ebcb%40%3Cannounce.tomcat.apache.org%3E"},{"type":"FIX","url":"http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html"},{"type":"FIX","url":"http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html"},{"type":"FIX","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html"},{"type":"FIX","url":"https://lists.apache.org/thread.html/1dd0a59c1295cc08ce4c9e7edae5ad2268acc9ba55adcefa0532e5ba%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/388a323769f1dff84c9ec905455aa73fbcb20338e3c7eb131457f708%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/3d19773b4cf0377db62d1e9328bf9160bf1819f04f988315086931d7%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/5c0e00fd31efc11e147bf99d0f03c00a734447d3b131ab0818644cdb%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/6af47120905aa7d8fe12f42e8ff2284fb338ba141d3b77b8c7cb61b3%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/845312a10aabbe2c499fca94003881d2c79fc993d85f34c1f5c77424%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/88855876c33f2f9c532ffb75bfee570ccf0b17ffa77493745af9a17a%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/b5e3f51d28cd5d9b1809f56594f2cf63dcd6a90429e16ea9f83bbedc%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/e85e83e9954f169bbb77b44baae5a33d8de878df557bb32b7f793661%40%3Cdev.tomcat.apache.org%3E"},{"type":"FIX","url":"https://lists.apache.org/thread.html/eb6efa8d59c45a7a9eff94c4b925467d3b3fec8ba7697f3daa314b04%40%3Cd
