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
In Octopus Deploy 3.0 onwards (before 2018.6.7), an authenticated user with incorrect permissions may be able to create Accounts under the Infrastructure menu.

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

Octopus Deploy versions 3.0 through 2018.6.6 contain a broken access control vulnerability where authenticated users with insufficient permissions can still create Accounts via the Infrastructure menu. The application fails to properly enforce authorization checks before allowing account creation.

MitigationUpgrade Octopus Deploy to version 2018.6.7 or later, which contains the fix for this permission bypass vulnerability.

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 Octopus Deploy version
    Access the Octopus Deploy web UI and navigate to the system health or about page, or check the installation directory for version information. Common locations include the UI footer, /about page, or the installation manifest file.
    Affected if The installed version falls within the range 3.0 to 2018.6.6 inclusive.
  2. Verify user role configuration
    Log into Octopus Deploy as an administrator and navigate to the Users or Teams configuration section to review defined roles and their permission levels.
    Affected if Roles other than Administrator or built-in high-privilege roles exist with limited permissions.
  3. Test Infrastructure menu access for low-privilege users
    Create or use a test user account assigned to a limited role (non-Administrator), then attempt to access the Infrastructure menu and navigate to the Accounts section.
    Affected if The limited user can access the Infrastructure menu and view the account creation interface without receiving an authorization error.
  4. Confirm account creation permission bypass
    Using the limited-privilege test user from the previous check, attempt to create a new Account (such as an Azure account or AWS account) via the Infrastructure menu.
    Affected if The account creation succeeds or the interface allows submission without triggering a permission denial message.

A user is affected if they run Octopus Deploy versions 3.0 through 2018.6.6 and have non-administrator accounts that can access the Infrastructure menu and create accounts despite lacking proper authorization.
