Description

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.

Affected configurations

• redhat ceph (< 14.2.21) • redhat ceph storage 4.0 • fedoraproject fedora 32 • fedoraproject fedora 33 • fedoraproject fedora 34 • debian debian linux 9.0
