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 affected versions of Octopus Deploy it is possible to discover network details via error message

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 · moderate confidence

In affected versions of Octopus Deploy, error messages expose network configuration details such as internal IP addresses, hostnames, or network topology information. This information disclosure could assist attackers in reconnaissance and mapping internal network architecture.

MitigationReview and sanitize all error message outputs to remove sensitive network details before returning them to users. Implement generic error messages for production environments while logging detailed diagnostic information server-side.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installed Octopus Server version
    Open the Octopus Web UI and navigate to the System node (gear icon) > About, or run 'octo version' from the command line if the Octopus CLI is installed
    Affected if Version cannot be determined or is not visible in the UI/CLI
  2. Compare version against first affected range
    Note the full version number (e.g., 2023.1.9500) and check if it is >= 3.0.0 AND < 2023.1.9879
    Affected if The installed version falls within this range (3.0.0 to 2023.1.9878)
  3. Compare version against second affected range
    If not in the first range, check if the version is >= 2023.2.2028 AND < 2023.2.8159
    Affected if The installed version falls within this range (2023.2.2028 to 2023.2.8158)
  4. Confirm default error handling is in use
    Verify that the Octopus Server is configured to return detailed error messages to users (this is the default configuration)
    Affected if Default error handling is active and error responses could be visible to authenticated or unauthenticated users

A user is affected if their Octopus Server version falls within either 3.0.0 to 2023.1.9879 or 2023.2.2028 to 2023.2.8159, and error messages are returned to clients without sanitization.

Interim mitigation

Review and sanitize all error message outputs to remove sensitive network details before returning them to users. Implement generic error messages for production environments while logging detailed diagnostic information server-side.

Recommended fix Moderate confidence

Upgrade to 2023.1.9879 or later (for 2023.1.x line), or 2023.2.8159 or later (for 2023.2.x line). For best results, upgrade to the latest stable 2023.3.x or 2024.x release.

  1. Identify your current Octopus Server version from the UI (Configuration > About) or via the API
  2. For versions >= 3.0.0 and < 2023.1.9879: Plan upgrade to version 2023.1.9879 or later in the 2023.1.x LTS line
  3. For versions >= 2023.2.2028 and < 2023.2.8159: Plan upgrade to version 2023.2.8159 or later, or migrate to the latest 2023.3.x/2024.x stable release
  4. Review Octopus Deploy upgrade documentation and release notes for your target version
  5. Backup your Octopus Server database and any relevant configuration
  6. Execute the upgrade following standard Octopus Server upgrade procedures
  7. Verify the upgrade was successful and test that error messages no longer expose network details
  8. After upgrading, confirm the vulnerability is resolved by triggering the previously affected functionality
Caveat Review release notes for your target version - major version upgrades may include database migrations or require attention to compatibility with existing deployments and integrations.
