{"id":"ALPINE-CVE-2021-3524","details":"A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway) in versions before 14.2.21. The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. In addition, the prior bug fix for CVE-2020-10753 did not account for the use of \\r as a header separator, thus a new flaw has been created.","modified":"2026-11-03T06:32:33.612133926Z","published":"2021-05-17T17:15:08.773Z","upstream":["CVE-2021-3524"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-3524"}],"affected":[{"package":{"name":"ceph","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/ceph?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3524.json"}},{"package":{"name":"ceph","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/ceph?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3524.json"}},{"package":{"name":"ceph","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/ceph?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3524.json"}},{"package":{"name":"ceph16","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/ceph16?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3524.json"}},{"package":{"name":"ceph16","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/ceph16?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3524.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
