{"id":"CVE-2016-0763","aliases":["GHSA-9hjv-9h75-xmpp"],"url":"https://o3.security/vulnerability/CVE-2016-0763","summary":"Improper Verification of Source of a Communication Channel in Apache Tomcat","details":"The setGlobalContext method in org/apache/naming/factory/ResourceLinkFactory.java in Apache Tomcat 7.x before 7.0.68, 8.x before 8.0.31, and 9.x before 9.0.0.M3 does not consider whether ResourceLinkFactory.setGlobalContext callers are authorized, which allows remote authenticated users to bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.","published":"2016-02-25T01:59:06.280Z","modified":"2026-10-24T10:30:23.923919423Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"7.0.68"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"8.0.32"},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat","fixedVersion":"9.0.0.M3"}],"fix":{"url":"https://github.com/apache/tomcat/commit/76ebc9007567c8326217dd94844540e1e27d8468","label":"apache/tomcat@76ebc90"},"references":[{"type":"WEB","url":"http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179356.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00047.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00069.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00085.html"},{"type":"WEB","url":"http://seclists.org/bugtraq/2016/Feb/147"},{"type":"WEB","url":"http://svn.apache.org/viewvc?view=revision&revision=1725926"},{"type":"WEB","url":"http://svn.apache.org/viewvc?view=revision&revision=1725929"},{"type":"WEB","url":"http://svn.apache.org/viewvc?view=revision&revision=1725931"},{"type":"WEB","url":"http://www.securityfocus.com/bid/83326"},{"type":"WEB","url":"http://www.securitytracker.com/id/1035069"},{"type":"WEB","url":"https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05150442"},{"type":"WEB","url":"https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05158626"},{"type":"WEB","url":"https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05324755"},{"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/r9136ff5b13e4f1941360b5a309efee2c114a14855578c3a2cbe5d19c%40%3Cdev.tomcat.apache.org%3E"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-1089.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-2599.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-2807.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-2808.html"},{"type":"ADVISORY","url":"http://tomcat.apache.org/security-7.html"},{"type":"ADVISORY","url":"http://tomcat.apache.org/security-8.html"},{"type":"ADVISORY","url":"http://tomcat.apache.org/security-9.html"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3530"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3552"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3609"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-3024-1"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2016:1087"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2016:1088"},{"type":"ADVISORY","url":"https://bto.bluecoat.com/security-advisory/sa118"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201705-09"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180531-0001/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2016-0763"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/76ebc9007567c8326217dd94844540e1e27d8468"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/c08641da04d31f730b56b8675301e55db97dfe88"},{"type":"WEB","url":"https://github.com/apache/tomcat80/commit/0531f7aeff1999d362e0a68512a3517f2cf1a6ae"},{"type":"WEB","url":"https://web.archive.org/web/20160404202803/http://www.securitytracker.com/id/1035069"},{"type":"WEB","url":"https://web.archive.org/web/20160314101138/http://www.securityfocus.com/bid/83326"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20180531-0001"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9136ff5b13e4f1941360b5a309efee2c114a14855578c3a2cbe5d19c@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/343558d982879bf88ec20dbf707f8c11255f8e219e81d45c4f8d0551@%3Cdev.tomcat.apache.org%3E"},{"type":"PACKAGE","url":"https://github.com/apache/tomcat"}],"provenance":{"sources":["OSV.dev","FIRST.org
