CVE-2021-3524

Disclosure Date: May 17, 2021 •
CVE-2021-3524 CVSS v3 Base Score: 6.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

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.
