Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
OpenStack Keystone Grizzly before 2013.1, Folsom 2012.1.3 and earlier, and Essex does not properly check if the (1) user, (2) tenant, or (3) domain is enabled when using EC2-style authentication, which allows context-dependent attackers to bypass access restrictions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OpenStack Keystone's EC2-style authentication mechanism fails to validate whether the user, tenant, or domain is in an enabled state before allowing access. This allows authenticated attackers with valid EC2 credentials to bypass access restrictions and potentially access resources even after their account, tenant, or domain has been disabled.

MitigationUpgrade Keystone to Grizzly 2013.1 or later, Folsom 2012.1.4 or later, or apply the vendor patch for Essex versions. Alternatively, disable EC2-style authentication if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Keystone version
    Run 'keystone --version' or check the package manager (dpkg -l | grep keystone, rpm -qa | grep keystone) to find the installed Keystone version
    Affected if Version is 2012.1.3 or earlier in the 2012.1 branch, 2012.2.4 or earlier in the 2012.2 branch, or exactly 2013.1
  2. Confirm EC2 credential usage
    Review your Keystone configuration file (typically keystone.conf) for any ec2_* settings, or check if any users have ec2 credentials (access keys) issued
    Affected if EC2-style credentials exist in the system
  3. Check EC2 authentication endpoint
    List Keystone endpoints and verify that EC2-style authentication service endpoint exists (typically /v2.0/ec2tokens)
    Affected if EC2 authentication endpoint is registered and accessible
  4. Inspect token validation settings
    Examine Keystone configuration for token validation settings, specifically looking at whether the 'enabled' flag is being checked during EC2-style authentication
    Affected if EC2 credentials can be validated without checking user/tenant/domain enabled status

Your environment is affected if you run a vulnerable Keystone version AND have EC2-style authentication enabled, because disabled accounts can still authenticate via EC2 credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 2012.2.4
Interim mitigation

Upgrade Keystone to Grizzly 2013.1 or later, Folsom 2012.1.4 or later, or apply the vendor patch for Essex versions. Alternatively, disable EC2-style authentication if not required.
