A flaw was found in ceph-dashboard. The JSON Web Token (JWT) used for user authentication is stored by the frontend application in the browser’s localStorage which is potentially vulnerable to attackers via XSS attacks. The highest threat from this vulnerability is to data confidentiality and integrity.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4998-1 advisory.

    It was discovered that in some situations Ceph logged passwords from the mgr module in clear text. An     attacker could use this to expose sensitive information. (CVE-2020-25678)

    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)

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)
