{"id":"UBUNTU-CVE-2019-0220","details":"A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them.","modified":"2026-01-30T02:15:26.797101Z","published":"2019-04-02T00:00:00Z","related":["USN-3937-1"],"upstream":["CVE-2019-0220"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-0220"},{"type":"REPORT","url":"https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2019-0220"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3937-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-0220"}],"affected":[{"package":{"name":"apache2","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.7-1ubuntu4.22?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.7-1ubuntu4.22"}]}],"versions":["2.4.6-2ubuntu2","2.4.6-2ubuntu3","2.4.6-2ubuntu4","2.4.7-1ubuntu1","2.4.7-1ubuntu2","2.4.7-1ubuntu3","2.4.7-1ubuntu4","2.4.7-1ubuntu4.1","2.4.7-1ubuntu4.4","2.4.7-1ubuntu4.5","2.4.7-1ubuntu4.6","2.4.7-1ubuntu4.7","2.4.7-1ubuntu4.8","2.4.7-1ubuntu4.9","2.4.7-1ubuntu4.10","2.4.7-1ubuntu4.11","2.4.7-1ubuntu4.13","2.4.7-1ubuntu4.15","2.4.7-1ubuntu4.16","2.4.7-1ubuntu4.17","2.4.7-1ubuntu4.18","2.4.7-1ubuntu4.19","2.4.7-1ubuntu4.20","2.4.7-1ubuntu4.21"],"ecosystem_specific":{"availability":"No
