CVE-2021-3524

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.
