CVE-2022-3277: Bug #1988026 “Neutron should not create security group with proj...” : Bugs : neutron

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.

CVE
#dos#auth

When a non-admin user tries to list security groups for project_id "None", Neutron creates a default security group for that project and returns an empty list to the caller.

To reproduce:

openstack --os-cloud devstack security group list --project None
openstack --os-cloud devstack-admin security group list

The API call that is made is essentially

GET /networking/v2.0/security-groups?project_id=None

The expected result would be an authorization failure, since normal users should not be allowed to list security groups for other projects.
