An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service.

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2023:0275 advisory.

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

    Security Fix(es):

    * unrestricted creation of security groups (CVE-2022-3277)

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

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.
