A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). 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. Ceph versions 3.x and 4.x are vulnerable to this issue.

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

  - A flaw was found in the Ceph RGW configuration with Beast as the front end handling client requests. 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-2019-10222)

  - A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). 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. Ceph versions 3.x and 4.x are vulnerable to this issue. (CVE-2020-10753)

  - An issue was discovered in Ceph through 13.2.9. A POST request with an invalid tagging XML can crash the     RGW process by triggering a NULL pointer exception. (CVE-2020-12059)

  - 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-2020-1700)

  - 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-2020-1760)

  - A flaw was found in ceph in versions prior to 16.y.z where 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-2020-25678)

  - 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)

  - 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.
    (CVE-2021-20288)

  - 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)

  - A key length flaw was found in Red Hat Ceph Storage. An attacker can 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-2021-3979)

  - A flaw was found in rgw. This flaw allows an unprivileged user to 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 bucket's name     used to sign the request. This issue results in a user being able to upload to any bucket accessible by     the specified access key as long as the bucket in the POST policy matches the bucket in the said POST form     part. (CVE-2023-43040) (CVE-2023-43040)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    Security Fix(es):

    * ceph: radosgw: HTTP header injection via CORS ExposeHeader tag (CVE-2020-10753)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * Previously, BlueFS failed to replay log which was corrupted due to a previous written replay log. The     BlueFS log corruption was caused by the BlueFS log growing exponentially because of OSD functioning in a     way where sync_metadata was not invoked in some situations and if sync_metadata was invoked the BlueFS log     was not getting compacted even though there is no new log data to flush. This log corruption caused     Bluestore not to be mounted and data loss in multiple OSDs. With this update, sync_metadata is now     invoked, BlueFS log is getting compacted even though  there is no new log data to flush in sync_metadata,     and avoid log corruption if log is expanded. This prevents OSDs getting full due to BlueFS log growing     exponentially and also BlueFS getting corrupted. As a result, logs replay and there is no data loss.
