A flaw was found in the Cephx authentication protocol in versions before 15.2.6 and before 14.2.14, where it does not verify Ceph clients correctly and is then vulnerable to replay attacks in Nautilus. This flaw allows an attacker with access to the Ceph cluster network to authenticate with the Ceph service via a packet sniffer and perform actions allowed by the Ceph service. This issue is a reintroduction of CVE-2018-1128, affecting the msgr2 protocol. The msgr 2 protocol is used for all communication except older clients that do not support the msgr2 protocol. The msgr1 protocol is not affected. The highest threat from this vulnerability is to confidentiality, integrity, and system availability.

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

  - An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon
    and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized
    resources. This flaw allows an authenticated client to modify the configuration and possibly conduct
    further attacks. (CVE-2020-10736)

  - 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 Cephx authentication protocol in versions before 15.2.6 and before 14.2.14, where
    it does not verify Ceph clients correctly and is then vulnerable to replay attacks in Nautilus. This flaw
    allows an attacker with access to the Ceph cluster network to authenticate with the Ceph service via a
    packet sniffer and perform actions allowed by the Ceph service. This issue is a reintroduction of
    CVE-2018-1128, affecting the msgr2 protocol. The msgr 2 protocol is used for all communication except
    older clients that do not support the msgr2 protocol. The msgr1 protocol is not affected. The highest
    threat from this vulnerability is to confidentiality, integrity, and system availability. (CVE-2020-25660)

    threat from this vulnerability is to confidentiality, integrity, and system availability. (CVE-2020-25660)

  - 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)

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4706-1 advisory.

    Olle Segerdahl found that ceph-mon and ceph-mgr daemons did not properly restrict access, resulting in     gaining access to unauthorized resources. An authenticated user could use this vulnerability to modify the     configuration and possibly conduct further attacks. (CVE-2020-10736)

    Adam Mohammed found that Ceph Object Gateway was vulnerable to HTTP header injection via a CORS     ExposeHeader tag. An attacker could use this to gain access or cause a crash. (CVE-2020-10753)

    Ilya Dryomov found that Cephx authentication did not verify Ceph clients correctly and was then vulnerable     to replay attacks in Nautilus. An attacker could use the Ceph cluster network to authenticate via a packet     sniffer and perform actions. This issue is a reintroduction of CVE-2018-1128. (CVE-2020-25660)

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0081 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.

    The ceph-ansible package provides Ansible playbooks for installing, maintaining, and upgrading Red Hat     Ceph Storage.

    This package contains a new implementation of the original libtirpc, transport-independent RPC (TI-RPC)     library for NFS-Ganesha.

    NFS-GANESHA is a NFS Server running in user space. It comes with various back-end modules (called FSALs)     provided as shared objects to support different file systems and name-spaces.

    Security Fix(es):

    * ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila     (CVE-2020-27781)

    * ceph: CEPHX_V2 replay attack protection lost (CVE-2020-25660)

    * ceph-ansible: insecure ownership on /etc/ceph/iscsi-gateway.conf configuration file (CVE-2020-25677)
