Open redirect vulnerability in views/auth_forms.py in OpenStack Dashboard (Horizon) Essex (2012.1) allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the next parameter to auth/login/. NOTE: this issue was originally assigned CVE-2012-3542 by mistake.

OpenStack Keystone, as used in OpenStack Folsom before folsom-rc1 and OpenStack Essex (2012.1), allows remote attackers to add an arbitrary user to an arbitrary tenant via a request to update the user's default tenant to the administrative API. NOTE: this identifier was originally incorrectly assigned to an open redirect issue, but the correct identifier for that issue is CVE-2012-3540.
