Debian DLA-3629-1 : ceph - LTS security update

high Nessus Plugin ID 183749

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

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.

Solution

Upgrade the ceph packages.

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