[Openstack-security] [Bug 1824248] Re: Security Group filtering hides rules from user

commit 1920a37a94b7a9589dcf83f6ff0765068560dbf8
Author: Slawek Kaplonski <skaplons at redhat.com>

    Show all SG rules belong to SG in group's details
    
    If security group contains rule(s) which were created by different
    user (admin), owner of this security group should see such rules
    even if those rules don't belong to him.
    
    This patch changes to use admin_context to get security group rules
    in get_security_group() method to achieve that.
    
    Test to cover such case is added in neutron-tempest-plugin repo.

Title:
  Security Group filtering hides rules from user

Status in neutron:
  Fix Released
Status in OpenStack Security Advisory:
  Won't Fix

Bug description:
  Manage Rules part of the GUI hides the rules currently visible in the
  Launch Instance modal window.

  It allows a malicious admin to add backdoor access rules that might be
  later added to VMs without the knowledge of owner of those VMs.

  When sending GET request as below, it responds only with the rules
  that are created by user and this happens when using Manage Rules part
  of the GUI: <WSGIRequest: GET
  '/project/security_groups/3a833936-f485-4a37-bb5b-d4694c7e18eb/'>

  On the other hand when using GET request as below, it responds with
  all SG and it includes all rules, and there is no filtering and this
  is used in Launch Instance modal window: <WSGIRequest: GET
  '/api/network/securitygroups/'>

  Here is example of rules display in Manage Rules part of GUI:

  > /opt/stack/horizon/openstack_dashboard/dashboards/project/security_groups/views.py(50)_get_data()

  As you might have noticed there are no ports access 44 and 22 (SSH)

  And from the Launch Instance Modal Window, as well as CLI we can see
  that there are two more rules that are invisible for user, port 44 and
