CVE-2021-3524: HTTP header injects via CORS in RGW
|
||
|
|
==================================================
|
||
|
|
|
||
|
|
* `NIST information page <https://nvd.nist.gov/vuln/detail/CVE-2021-3524>`_
|
||
|
|
|
||
|
|
A flaw was found in the radosgw. The vulnerability is related to the
|
||
|
|
injection of HTTP headers via a CORS ExposeHeader tag. The \r
|
||
|
|
character in the ExposeHeader tag in the CORS configuration file
|
||
|
|
generates a header injection in the response when the CORS request is
|
||
|
|
made.
