CVSS: 6.8EPSS: 0%CPEs: 5EXPL: 0CVE-2022-3277 – openstack-neutron: unrestricted creation of security groups
https://notcve.org/view.php?id=CVE-2022-3277
08 Dec 2022 — 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. David Sinquin discovered that OpenStack Neutron incorrectly handled the default Open vSwitch firewall rules. • https://bugs.launchpad.net/neutron/+bug/1988026 • CWE-400: Uncontrolled Resource Consumption •

23 Aug 2021 — 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.

CVSS: 7.1EPSS: 4%CPEs: 8EXPL: 1CVE-2019-9735 – openstack-neutron: incorrect validation of port settings in iptables security group driver
https://notcve.org/view.php?id=CVE-2019-9735
13 Mar 2019 — An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that doesn't support that option (for example, VRRP), an authenticated user may block further application of security group rules for instances from any project/tenant on the compute hosts to which it's applied.
