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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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 Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3629 advisory.

    Package        : ceph     Version        : 12.2.11+dfsg1-2.1+deb10u1     CVE ID         : CVE-2019-10222 CVE-2020-1700 CVE-2020-1760 CVE-2020-10753                      CVE-2020-12059 CVE-2020-25678 CVE-2020-27781 CVE-2021-3524                      CVE-2021-3531 CVE-2021-3979 CVE-2021-20288 CVE-2023-43040     Debian Bug     : 1053690

    Multiple vulnerabilities were fixed in Ceph, a massively scalable,     open-source, distributed storage system that runs on commodity hardware     and delivers object, block and file system storage.

    CVE-2019-10222

        A Denial of service was fixed: An unauthenticated attacker could crash         the Ceph RGW server by sending valid HTTP headers and terminating the         connection, resulting in a remote denial of service for Ceph RGW clients.

    CVE-2020-1700

        A Denial of Service was fixed: A flaw was found in the way the Ceph RGW         Beast front-end handles unexpected disconnects. An authenticated attacker         can abuse this flaw by making multiple disconnect attempts resulting in a         permanent leak of a socket connection by radosgw. This flaw could lead to         a denial of service condition by pile up of CLOSE_WAIT sockets, eventually         leading to the exhaustion of available resources, preventing legitimate         users from connecting to the system.

    CVE-2020-1760

        A XSS attack was fixed: A flaw was found in the Ceph Object Gateway,         where it supports request sent by an anonymous user in Amazon S3.
        This flaw could lead to potential XSS attacks due to the lack         of proper neutralization of untrusted input.

    CVE-2020-10753

        A Header Injection attack was fixed: It was possible to         inject HTTP headers via a CORS ExposeHeader tag in an Amazon S3 bucket. 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.

    CVE-2020-12059

        A Denial of Service was fixed: A POST request with an invalid tagging         XML could crash the RGW process by triggering a NULL pointer exception.

    CVE-2020-25678

        An Information Disclosure was fixed: ceph stores mgr module passwords         in clear text. This can be found by searching the mgr logs for grafana and         dashboard, with passwords visible.

    CVE-2020-27781

        A Privilege Escalation was fixed: User credentials could 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.

    CVE-2021-3524

        Similar to CVE-2020-10753, a Header Injection attack was fixed:
        It was possible to inject HTTP headers via a CORS ExposeHeader         tag in an Amazon S3 bucket

    CVE-2021-3531

        A Denial of Service was fixed: When processing a GET Request in Ceph         Storage RGW for a swift URL that ends with two slashes it could cause the         rgw to crash, resulting in a denial of service.

    CVE-2021-3979

        A Loss of Confidentiality was fixed: A key length flaw was found in         Ceph Storage. An attacker could exploit the fact that the key length is         incorrectly passed in an encryption algorithm to create a non random key,         which is weaker and can be exploited for loss of confidentiality and         integrity on encrypted disks.

    CVE-2021-20288

        A Potential Privilege Escalation was fixed: When handling         CEPHX_GET_PRINCIPAL_SESSION_KEY requests, ignore CEPH_ENTITY_TYPE_AUTH in         CephXServiceTicketRequest::keys.

    CVE-2023-43040

        A flaw was found in Ceph RGW. An unprivileged         user can write to any bucket(s) accessible by a given key         if a POST's form-data contains a key called 'bucket'         with a value matching the name of the bucket used to sign         the request. The result of this is that a user could actually         upload to any bucket accessible by the specified access key         as long as the bucket in the POST policy matches the bucket         in said POST form part.

    For Debian 10 buster, these problems have been fixed in version     12.2.11+dfsg1-2.1+deb10u1.

    We recommend that you upgrade your ceph packages.
