Goutham Pacha Ravi, Jahson Babel, and John Garbutt discovered that user
credentials in Ceph could be manipulated in certain environments. An
attacker could use this to gain unintended access. (CVE-2020-27781)

It was discovered that the Ceph dashboard was susceptible to a cross-site
scripting attack. An attacker could use this to expose sensitive
information or gain unintended access. (CVE-2020-27839)

It was discovered that Ceph contained an authentication flaw, leading to
key reuse. An attacker could use this to cause a denial of service or
possibly impersonate another user. (CVE-2021-20288)

Sergey Bobrov discovered that the Ceph dashboard was susceptible to a
cross-site scripting attack. An attacker could use this to expose sensitive
information or gain unintended access. (CVE-2021-3509)

Sergey Bobrov discovered that Ceph's RadosGW (Ceph Object Gateway) allowed
the injection of HTTP headers in responses to CORS requests. An attacker
could use this to violate system integrity. (CVE-2021-3524)

It was discovered that Ceph's RadosGW (Ceph Object Gateway) did not
properly handle GET requests for swift URLs in some situations, leading to
an application crash. An attacker could use this to cause a denial of
service. (CVE-2021-3531)");
