It was found in Ceph versions before 13.2.4 that authenticated ceph RGW users can cause a denial of service against OMAPs holding bucket indices.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2735 advisory.

  - It was found Ceph versions before 13.2.4 that authenticated ceph users with read only permissions could     steal dm-crypt encryption keys used in ceph disk encryption. (CVE-2018-14662)

  - It was found in Ceph versions before 13.2.4 that authenticated ceph RGW users can cause a denial of     service against OMAPs holding bucket indices. (CVE-2018-16846)

  - 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)

  - 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 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)

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

An update of the ceph package has been released.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2538 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.

    Security Fix(es):

    * ceph: ListBucket max-keys has no defined limit in the RGW codebase (CVE-2018-16846)

    * ceph: debug logging for v4 auth does not sanitize encryption keys (CVE-2018-16889)

    * ceph: authenticated user with read only permissions can steal dm-crypt / LUKS key (CVE-2018-14662)

According to the version of the ceph packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A flaw was found in the way the ListBucket function     max-keys has no defined limit in the RGW codebase. An     authenticated ceph RGW user can cause a denial of     service attack against OMAPs holding bucked     indices.(CVE-2018-16846)

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4035-1 advisory.

    It was discovered that Ceph incorrectly handled read only permissions. An authenticated attacker could use     this issue to obtain dm-crypt encryption keys. This issue only affected Ubuntu 16.04 LTS. (CVE-2018-14662)

    It was discovered that Ceph incorrectly handled certain OMAPs holding bucket indices. An authenticated     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04     LTS. (CVE-2018-16846)

    It was discovered that Ceph incorrectly sanitized certain debug logs. A local attacker could possibly use     this issue to obtain encryption key information. This issue was only addressed in Ubuntu 18.10 and Ubuntu     19.04. (CVE-2018-16889)

    It was discovered that Ceph incorrectly handled certain civetweb requests. A remote attacker could     possibly use this issue to consume resources, leading to a denial of service. This issue only affected     Ubuntu 18.10 and Ubuntu 19.04. (CVE-2019-3821)
