Doc Text:
It was found that RBAC policies were not enforced in certain methods of the OpenStack Compute EC2 (Amazon Elastic Compute Cloud) API. A remote attacker could use this flaw to escalate their privileges beyond the user group they were originally restricted to. Note that only certain setups using non-default RBAC rules for OpenStack Compute were affected.

Description Garth Mollett 2014-04-07 05:40:50 UTC 
Tristan Cacqueray reports:

Title: RBAC policy not properly enforced in Nova EC2 API
Reporter: Marc Heckmann (Ubisoft)
Products: Nova
Versions: 2013.1 versions up to 2013.2.3

Description:
Marc Heckmann from Ubisoft reported a vulnerability in the Nova EC2 API
security group implementation. RBAC policies are not enforced when using
the EC2 API, in particular the add_rules, remove_rules and destroy
methods. A restricted user may overcome his limitation by using EC2 API
resulting in unauthorized action on security groups. Only setups using
non-default RBAC rules for Nova may be affected.
