{"id":"DEBIAN-CVE-2016-5387","details":"The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an \"httpoxy\" issue.  NOTE: the vendor states \"This mitigation has been assigned the identifier CVE-2016-5387\"; in other words, this is not a CVE ID for a vulnerability.","modified":"2026-09-01T16:04:11.890372572Z","published":"2016-07-19T02:00:19.837Z","upstream":["CVE-2016-5387"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2016-5387"}],"affected":[{"package":{"name":"apache2","ecosystem":"Debian:12","purl":"pkg:deb/debian/apache2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.23-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-5387.json"}},{"package":{"name":"apache2","ecosystem":"Debian:13","purl":"pkg:deb/debian/apache2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.23-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-5387.json"}},{"package":{"name":"apache2","ecosystem":"Debian:14","purl":"pkg:deb/debian/apache2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.23-2"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2016-5387.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
