CVE-2018-12089
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 · uneditedIn Octopus Deploy version 2018.5.1 to 2018.5.7, a user with Task View is able to view a password for a Service Fabric Cluster, when the Service Fabric Cluster target is configured in Azure Active Directory security mode and a deployment is executed with OctopusPrintVariables set to True. This is fixed in 2018.6.0.
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 confidenceIn Octopus Deploy 2018.5.1-2018.5.7, a user with only Task View permission can view sensitive Service Fabric Cluster passwords in plaintext when the cluster uses Azure Active Directory security mode and the deployment is executed with OctopusPrintVariables set to True. This exposes credentials to users who should not have access to them.

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.
-
Check your Octopus Server versionOpen the Octopus Web UI, go to Configuration > About, or run `octo version` from the command line. Note the full version number.Affected if The version is 2018.5.1, 2018.5.2, 2018.5.3, 2018.5.4, 2018.5.5, 2018.5.6, or 2018.5.7
-
Identify Service Fabric Cluster deployment targetsIn the Octopus Web UI, go to Infrastructure > Deployment Targets. Look for any targets of type Service Fabric Cluster.Affected if You have one or more Service Fabric Cluster deployment targets configured
-
Check if Service Fabric targets use Azure Active Directory securityFor each Service Fabric Cluster target, view its details and inspect the Security Mode setting. Look for configurations that specify Azure Active Directory (AAD) as the security provider.Affected if Any Service Fabric Cluster target is configured with Azure Active Directory security mode
-
Check for OctopusPrintVariables=True in deployment processesIn the Octopus Web UI, go to Projects > your project > Variables. Also check any step templates or run conditions that set the variable OctopusPrintVariables to True. Search across all projects for this variable setting.Affected if The variable OctopusPrintVariables is set to True in any project that deploys to Service Fabric Cluster targets
You are affected if your Octopus Server version is between 2018.5.1 and 2018.5.7 AND you have Service Fabric Cluster targets using Azure AD security mode with OctopusPrintVariables enabled in deployment processes.

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 dataUpgrade to Octopus Deploy 2018.6.0 or later to patch the vulnerability. As a workaround, avoid setting OctopusPrintVariables=True when deploying to Service Fabric Cluster targets.
