"According to the versions of the ceph-common packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

  - A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). 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. Ceph versions 3.x and 4.x are vulnerable to this issue. (CVE-2020-10753)

  - 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. (CVE-2021-3524)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
