[Yahoo-eng-team] [Bug 1493448] Re: All operations are perfomed with admin priveleges when 'use_user_token' is False
"use_user_token" and related glance config options were deprecated in Mitaka: https://review.openstack.org/#/c/237742/ Bug may be closed. ** Changed in: glance Status: Triaged => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to Glance. https://bugs.launchpad.net/bugs/1493448 Title: All operations are perfomed with admin priveleges when 'use_user_token' is False Status in Glance: Fix Released Status in OpenStack Security Advisory: Won't Fix Status in OpenStack Security Notes: Fix Released Bug description: In glance-api.conf we have a param called 'use_user_token' which is enabled by default. It was introduced to allow for reauthentication when tokens expire and prevents requests from silently failing. https://review.openstack.org/#/c/29967/ Unfortunately disabling this parameter leads to security issues and allows a regular user to perform any operation with admin rights. Steps to reproduce on devstack: 1. Change /etc/glance/glance-api.conf parameters and restart glance-api: # Pass the user's token through for API requests to the registry. # Default: True use_user_token = False # If 'use_user_token' is not in effect then admin credentials # can be specified. Requests to the registry on behalf of # the API will use these credentials. # Admin user name admin_user = glance # Admin password admin_password = nova # Admin tenant name admin_tenant_name = service # Keystone endpoint auth_url = http://127.0.0.1:5000/v2.0 (for v2 api it's required to enable registry service, too: data_api = glance.db.registry.api) 2.
