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.

  - User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting     in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary     cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all     users of the requesting OpenStack project can view the access key. This enables the attacker to target any     resource that the user has access to. This can be done to even admin users, compromising the ceph     administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to     16.2.0. (CVE-2020-27781)

  - 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)

  - An authentication flaw was found in ceph in versions before 14.2.20. When the monitor handles     CEPHX_GET_AUTH_SESSION_KEY requests, it doesn't sanitize other_keys, allowing key reuse. An attacker who     can request a global_id can exploit the ability of any user to request a global_id previously associated     with another user, as ceph does not force the reuse of old keys to generate new ones. The highest threat     from this vulnerability is to data confidentiality and integrity as well as system availability.

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