{"id":"CVE-2016-5386","details":"The net/http package in Go through 1.6 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an \"httpoxy\" issue.","aliases":["GO-2022-0761"],"modified":"2026-04-16T01:41:10.646968045Z","published":"2016-07-19T02:00:18.757Z","related":["openSUSE-SU-2016:2054-1","openSUSE-SU-2016:2055-1","openSUSE-SU-2016:2536-1","openSUSE-SU-2024:10802-1","openSUSE-SU-2024:10803-1","openSUSE-SU-2024:10804-1","openSUSE-SU-2024:10805-1","openSUSE-SU-2024:10811-1","openSUSE-SU-2024:10812-1"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7WGHKKCFP4PLVSWQKCM3FJJPEWB5ZNTU/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OR52UXGM6RKSCWF3KQMVZGVZVJ3WEESJ/"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-1538.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html"},{"type":"ADVISORY","url":"https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03770en_us"},{"type":"ADVISORY","url":"https://httpoxy.org/"},{"type":"ADVISORY","url":"http://www.kb.cert.org/vuls/id/797896"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1353798"},{"type":"FIX","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/golang/go","events":[{"introduced":"0"},{"last_affected":"53da5fd4d431881bb3583c9790db7735a6530a1b"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"1.7-rc1"}]}}],"versions":["go1.3beta1","go1.3beta2","go1.4beta1","go1.5beta1","go1.5beta2","go1.5beta3","go1.6beta1","go1.6beta2","go1.7beta1","go1.7beta2","go1.7rc1","release.r56","weekly","weekly.2009-11-06","weekly.2009-11-10","weekly.2009-11-10.1","weekly.2009-11-12","weekly.2009-11-17","weekly.2009-12-07","weekly.2009-12-09","weekly.2009-12-22","weekly.2010-01-05","weekly.2010-01-13","weekly.2010-01-27","weekly.2010-02-04","weekly.2010-02-17","weekly.2010-02-23","weekly.2010-03-04","weekly.2010-03-15","weekly.2010-03-22","weekly.2010-03-30","weekly.2010-04-13","weekly.2010-04-27","weekly.2010-05-04","weekly.2010-05-27","weekly.2010-06-09","weekly.2010-06-21","weekly.2010-07-01","weekly.2010-07-14","weekly.2010-07-29","weekly.2010-08-04","weekly.2010-08-11","weekly.2010-08-25","weekly.2010-09-06","weekly.2010-09-15","weekly.2010-09-22","weekly.2010-09-29","weekly.2010-10-13","weekly.2010-10-13.1","weekly.2010-10-20","weekly.2010-10-27","weekly.2010-11-02","weekly.2010-11-10","weekly.2010-11-23","weekly.2010-12-02","weekly.2010-12-08","weekly.2010-12-15","weekly.2010-12-15.1","weekly.2010-12-22","weekly.2011-01-06","weekly.2011-01-12","weekly.2011-01-19","weekly.2011-01-20","weekly.2011-02-01","weekly.2011-02-01.1","weekly.2011-02-15","weekly.2011-02-24","weekly.2011-03-07","weekly.2011-03-07.1","weekly.2011-03-15","weekly.2011-03-28","weekly.2011-04-04","weekly.2011-04-13","weekly.2011-04-27","weekly.2011-05-22","weekly.2011-06-02","weekly.2011-06-09","weekly.2011-06-16","weekly.2011-06-23","weekly.2011-07-07","weekly.2011-07-19","weekly.2011-07-29","weekly.2011-08-10","weekly.2011-08-17","weekly.2011-09-01","weekly.2011-09-07","weekly.2011-09-16","weekly.2011-09-21","weekly.2011-10-06","weekly.2011-10-18","weekly.2011-10-25","weekly.2011-10-26","weekly.2011-11-01","weekly.2011-11-02","weekly.2011-11-08","weekly.2011-11-09","weekly.2011-11-18","weekly.2011-12-01","weekly.2011-12-02","weekly.2011-12-06","weekly.2011-12-14","weekly.2011-12-22","weekly.2012-01-15","weekly.2012-01-20","weekly.2012-01-27","weekly.2012-02-07","weekly.2012-02-14","weekly.2012-02-22","weekly.2012-03-04","weekly.2012-03-13","weekly.2012-03-22","weekly.2012-03-27"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"23"}]},{"events":[{"introduced":"0"},{"last_affected":"24"}]},{"events":[{"introduced":"0"},{"last_affected":"7"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.2"}]},{"events":[{"introduced":"0"},{"last_affected":"7.2"}]},{"events":[{"introduced":"1.0"},{"fixed":"1.6.3"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2016-5386.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
