| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
Red Hat Ceph Storage RadosGW (Ceph Object Gateway) versions prior to 14.2.21
Description
A flaw was found in the Red Hat Ceph Storage RadosGW 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. This issue is also related to insufficient input validation, which may allow a remote attacker to impact data integrity.
Recommendations
For versions prior to 14.2.21, update to version 14.2.21 or later to resolve the issue. As a temporary workaround, consider restricting access to the CORS configuration file to minimize the risk of exploitation. Avoid using the newline character in the ExposeHeader tag until the issue is resolved.
Fix
Special Elements Injection
RCE
