The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:3503 advisory.

    Neutron is a virtual network service for OpenStack. Just like OpenStack     Nova provides an API to dynamically request and configure virtual     servers, Neutron provides an API to dynamically request and configure     virtual networks. These networks connect interfaces from other     OpenStack services (e.g., virtual NICs from Nova VMs). The Neutron     API supports extensions to provide advanced network capabilities     (e.g., QoS, ACLs, network, monitoring, etc.).

    Security Fix(es):

    * arbitrary dnsmasq reconfiguration via extra_dhcp_opts (CVE-2021-40085)

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

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2781 advisory.

  - An issue was discovered in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1.
    Authenticated attackers can reconfigure dnsmasq via a crafted extra_dhcp_opts value. (CVE-2021-40085)

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

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4983 advisory.

  - A flaw was found in openstack-neutron's default Open vSwitch firewall rules. By sending carefully crafted     packets, anyone in control of a server instance connected to the virtual switch can impersonate the IPv6     addresses of other systems on the network, resulting in denial of service or in some cases possibly     interception of traffic intended for other destinations. Only deployments using the Open vSwitch driver     are affected. Source: OpenStack project. Versions before openstack-neutron 15.3.3, openstack-neutron     16.3.1 and openstack-neutron 17.1.1 are affected. (CVE-2021-20267)

  - OpenStack Neutron before 16.4.1, 17.x before 17.1.3, and 18.0.0 allows hardware address impersonation when     the linuxbridge driver with ebtables-nft is used on a Netfilter-based platform. By sending carefully     crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate     the hardware addresses of other systems on the network, resulting in denial of service or in some cases     possibly interception of traffic intended for other destinations. (CVE-2021-38598)

  - An issue was discovered in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1.
    Authenticated attackers can reconfigure dnsmasq via a crafted extra_dhcp_opts value. (CVE-2021-40085)

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6067-1 advisory.

    David Sinquin discovered that OpenStack Neutron incorrectly handled the default Open vSwitch firewall     rules. An attacker could possibly use this issue to impersonate the IPv6 addresses of other systems on the     network. This issue only affected Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-20267)

    Jake Yip and Justin Mammarella discovered that OpenStack Neutron incorrectly handled the linuxbridge     driver when ebtables-nft is being used. An attacker could possibly use this issue to impersonate the     hardware addresss of other systems on the network. This issue only affected Ubuntu 18.04 LTS, and Ubuntu     20.04 LTS. (CVE-2021-38598)

    Pavel Toporkov discovered that OpenStack Neutron incorrectly handled extra_dhcp_opts values. An attacker     could possibly use this issue to reconfigure dnsmasq. This issue only affected Ubuntu 18.04 LTS, and     Ubuntu 20.04 LTS. (CVE-2021-40085)

    Slawek Kaplonski discovered that OpenStack Neutron incorrectly handled the routes middleware. An attacker     could possibly use this issue to cause the API worker to consume memory, leading to a denial of service.
    This issue only affected Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS. (CVE-2021-40797)

    It was discovered that OpenStack Neutron incorrectly handled certain queries. A remote authenticated user     could possibly use this issue to cause resource consumption, leading to a denial of service.
    (CVE-2022-3277)
