A flaw was found in Red Hat Ceph Storage 4, in the Dashboard component. In response to CVE-2020-27839, the JWT token was moved from localStorage to an httpOnly cookie. However, token cookies are used in the body of the HTTP response for the documentation, which again makes it available to XSS.The greatest threat to the system is for confidentiality, integrity, and availability.

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5128-1 advisory.

    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 to resources.
    This issue only affected Ubuntu 18.04 LTS. (CVE-2020-27781)

    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. This issue only affected Ubuntu     21.04. (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. This issue only     affected Ubuntu 21.04. (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)

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1834-1 advisory.

  - A flaw was found in Red Hat Ceph Storage 4, in the Dashboard component. In response to CVE-2020-27839, the     JWT token was moved from localStorage to an httpOnly cookie. However, token cookies are used in the body     of the HTTP response for the documentation, which again makes it available to XSS.The greatest threat to     the system is for confidentiality, integrity, and availability. (CVE-2021-3509)

  - 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)

  - A flaw was found in the Red Hat Ceph Storage RGW in versions before 14.2.21. When processing a GET Request     for a swift URL that ends with two slashes it can cause the rgw to crash, resulting in a denial of     service. The greatest threat to the system is of availability. (CVE-2021-3531)

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:2445 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform that combines the most stable     version of the Ceph storage system with a Ceph management platform, deployment utilities, and support     services.

    The ceph-ansible package provides Ansible playbooks for installing, maintaining, and upgrading Red Hat     Ceph Storage.

    The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's     userspace passthrough interface (TCMU). It presents a C plugin API for extension modules that handle SCSI     requests in ways not possible or suitable to be handled by LIO's in-kernel backstores.

    Security Fix(es):

    * ceph: Unauthorized global_id reuse in cephx (CVE-2021-20288)

    * ceph-dashboard: Don't use Browser's LocalStorage for storing JWT but Secure Cookies with proper HTTP     Headers (CVE-2020-27839)

    * ceph-dashboard: Cross-site scripting via token Cookie (CVE-2021-3509)
