CVE-2020-15511
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 · uneditedHashiCorp Terraform Enterprise up to v202006-1 contained a default signup page that allowed user registration even when disabled, bypassing SAML enforcement. Fixed in v202007-1.
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 confidenceHashiCorp Terraform Enterprise versions up to v202006-1 contained a default user registration/signup page that remained accessible even when user registration was explicitly disabled in the system settings, allowing unauthorized account creation and bypassing SAML single sign-on enforcement controls.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Terraform Enterprise versionCheck the installed Terraform Enterprise version through the admin console or system information panel. This is typically visible in the UI under 'Settings' or 'System' information, or via the /api/v1/version endpoint if accessible.Affected if The installed version is any release prior to v202007-1 (for example, v202006-1, v202005-1, or earlier)
-
Verify user registration setting stateNavigate to the Terraform Enterprise admin settings and locate the user registration or signup configuration. Check whether the option to disable user registration is enabled.Affected if User registration is set to 'disabled' but the registration page remains accessible
-
Confirm SAML authentication is enforcedIn the Terraform Enterprise admin panel, verify that SAML single sign-on is configured and that the enforcement option to restrict authentication to SAML users only is enabled.Affected if SAML is configured and enforced in system settings
-
Test registration page accessibilityAttempt to access the user registration or signup endpoint directly (typically /signup or /register) while logged out. Observe whether the registration form is displayed despite registration being disabled in settings.Affected if The registration page loads and displays a signup form even when user registration is explicitly disabled in the admin settings
-
Verify unauthorized account creationSubmit a test registration through the accessible signup page using a non-SSO email address. Confirm whether an account can be created without SAML authentication.Affected if An account can be created without authenticating through SAML, bypassing the SSO enforcement control
You are affected if running any Terraform Enterprise version prior to v202007-1 and the user registration page is accessible despite being disabled in system settings, allowing unauthorized account creation outside SAML authentication.

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 data202007-1
Upgrade Terraform Enterprise to v202007-1 or later, and verify that user registration is properly disabled when SAML authentication is enforced.
