@Dolph indeed, knowledge of internalURL and adminURL does not constitute
a vulnerability. Thus it does not need an OSSA task and can be make
public for further discussion.

Title:
  internalURL and adminURL of endpoints should not be visible to
  ordinary user

Status in OpenStack Identity (Keystone):
  New

Bug description:
  if an ordinary user sent a get-token request to KeyStone, internalURL
  and adminURL of endpoints will also be returned. It'll expose the
  internal high privilege access address to the ordinary user, and leads
  to the risk for malicious user to attack or hijack the system.

  the request to get token for ordinary user:     
  curl -d '{"auth":{"passwordCredentials":{"username": "huawei", "password": "2014"},"tenantName":"huawei"}}' -H "Content-type: application/json" http://localhost:5000/v2.0/tokens

  the response:
  {"access": {"token": {"issued_at": "2014-11-27T02:30:59.218772", "expires": "2014-11-27T03:30:59Z", "id": "b8684d2b68ab49d5988da9197f38a878", "tenant": {"description": "normal Tenant", "enabled": true, "id": "7ed3351cd58349659f0bfae002f76a77", "name": "huawei"}, "audit_ids": ["Ejn3BtaBTWSNtlj7beE9bQ"]}, "serviceCatalog": [{"endpoints": [{"adminURL": "http://10.67.148.27:8774/v2/7ed3351cd58349659f0bfae002f76a77", "region": "regionOne", "internalURL": "http://10.67.148.27:8774/v2/7ed3351cd58349659f0bfae002f76a77", "id": "170a3ae617a1462c81bffcbc658b7746", "publicURL": "http://10.67.148.27:8774/v2/7ed3351cd58349659f0bfae002f76a77"}], "endpoints_links": [], "type": "compute", "name": "nova"}, {"endpoints": [{"adminURL": "http://10.67.148.27:9696", "region": "regionOne", "internalURL": "http://10.67.148.27:9696", "id": "7c0f28aa4710438bbd84fd25dbe4daa6", "publicURL": "http://10.67.148.27:9696"}], "endpoints_links": [], "type": "network", "name": "neutron"}, {"endpoints": [{"adminURL": "http://10.67.148.27:9292", "region": "regionOne", "internalURL": "http://10.67.148.27:9292", "id": "576f41fc8ef14b4f90e516bb45897491", "publicURL": "http://10.67.148.27:9292"}], "endpoints_links": [], "type": "image", "name": "glance"}, {"endpoints": [{"adminURL": "http://10.67.148.27:8777", "region": "regionOne", "internalURL": "http://10.67.148.27:8777", "id": "77d464e146f242aca3c50e10b6cfdaa0", "publicURL": "http://10.67.148.27:8777"}], "endpoints_links": [], "type": "metering", "name": "ceilometer"}, {"endpoints": [{"adminURL": "http://10.67.148.27:6385", "region": "regionOne", "internalURL": "http://10.67.148.27:6385", "id": "1b8177826e0c426fa73e5519c8386589", "publicURL": "http://10.67.148.27:6385"}], "endpoints_links": [], "type": "baremetal", "name": "ironic"}, {"endpoints": [{"adminURL": "http://10.67.148.27:35357/v2.0", "region": "regionOne", "internalURL": "http://10.67.148.27:5000/v2.0", "id": "435ae249fd2a427089cb4bf2e6c0b8e9", "publicURL": "http://10.67.148.27:5000/v2.0"}], "endpoints_links": [], "type": "identity", "name": "keystone"}], "user": {"username": "huawei", "roles_links": [], "id": "a88a40a635334e5da2ac3523d9780ed3", "roles": [{"name": "_member_"}], "name": "huawei"}, "metadata": {"is_admin": 0, "roles": ["73b0a1ac6b0c48cb90205c53f2b9e48d"]}}}
