This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected.

affected.","provenance":"source","from":"CVE.org"},"cvss":null,"epss":{"score":0.1707,"percentile":0.97067,"provenance":"source"},"cwes":[],"references":[{"url":"https://access.redhat.com/errata/RHSA-2018:1448","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://security.netapp.com/advisory/ntap-20180706-0001/","tags":["x_refsource_CONFIRM"]},{"url":"http://www.securityfocus.com/bid/103170","tags":["vdb-entry","x_refsource_BID"]},{"url":"http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html","tags":["x_refsource_CONFIRM"]},{"url":"https://access.redhat.com/errata/RHSA-2018:1449","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2018:1450","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://lists.apache.org/thread.html/b1d7e2425d6fd2cebed40d318f9365b44546077e10949b01b1f8a0fb%40%3Cannounce.tomcat.apache.org%3E","tags":["x_refsource_MISC"]},{"url":"https://www.debian.org/security/2018/dsa-4281","tags":["vendor-advisory","x_refsource_DEBIAN"]},{"url":"https://access.redhat.com/errata/RHSA-2018:2939","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2018:0465","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://usn.ubuntu.com/3665-1/","tags":["vendor-advisory","x_refsource_UBUNTU"]},{"url":"http://www.securitytracker.com/id/1040427","tags":["vdb-entry","x_refsource_SECTRACK"]},{"url":"https://access.redhat.com/errata/RHSA-2018:1320","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2018:1451","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://lists.debian.org/debian-lts-announce/2018/03/msg00004.html","tags":["mailing-list","x_refsource_MLIST"]},{"url":"http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html","tags":["x_refsource_CONFIRM"]},{"url":"https://lists.debian.org/debian-lts-announce/2018/07/msg00044.html","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://access.redhat.com/errata/RHSA-2018:0466","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2018:1447","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://lists.debian.org/debian-lts-announce/2018/06/msg00008.html","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/eb6efa8d59c45a7a9eff94c4b925467d3b3fec8ba7697f3daa314b04%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/388a323769f1dff84c9ec905455aa73fbcb20338e3c7eb131457f708%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/5c0e00fd31efc11e147bf99d0f03c00a734447d3b131ab0818644cdb%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/b5e3f51d28cd5d9b1809f56594f2cf63dcd6a90429e16ea9f83bbedc%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/88855876c33f2f9c532ffb75bfee570ccf0b17ffa77493745af9a17a%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/e85e83e9954f169bbb77b44baae5a33d8de878df557bb32b7f793661%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/845312a10aabbe2c499fca94003881d2c79fc993d85f34c1f5c77424%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/1dd0a59c1295cc08ce4c9e7edae5ad2268acc9ba55adcefa0532e5ba%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/3d19773b4cf0377db62d1e9328bf9160bf1819f04f988315086931d7%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/6af47120905aa7d8fe12f42e8ff2284fb338ba141d3b77b8c7cb61b3%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html","tags":["x_refsource_MISC"]},{"url":"https://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html","tags":["x_refsource_MISC"]},{"url":"https://access.redhat.com/errata/RHSA-2019:2205","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://lists.apache.org/thread.html/r6ccee4e849bc77df0840c7f853f6bd09d426f6741247da2b7429d5d9%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},{"url":"https://lists.apache.org/thread.html/r3bbb800a816d0a51eccc5a228c58736960a9fffafa581a225834d97d%40%3Cdev.tomcat.apache.org%3E","tags":["mailing-list","x_refsource_MLIST"]},
