CVE-2020-24566
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 2020.3.x before 2020.3.4 and 2020.4.x before 2020.4.1, if an authenticated user creates a deployment or runbook process using Azure steps and sets the step's execution location to run on the server/worker, then (under certain circumstances) the account password is exposed in cleartext in the verbose task logs output.
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 versions 2020.3.x before 2020.3.4 and 2020.4.x before 2020.4.1, authenticated users with permissions to create deployment or runbook processes can configure Azure steps to execute on the server/worker. Under certain circumstances related to verbose task logging, the Azure account password is written in cleartext to the task logs, resulting in credential exposure.

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 installed Octopus Deploy versionLog into the Octopus web UI and navigate to the Configuration > About page, or check the server/worker host for the installed version via the installer or service information.Affected if The version is 2020.3.x before 2020.3.4, or 2020.4.x before 2020.4.1.
-
Verify presence of Azure deployment stepsIn the Octopus web UI, review existing deployment processes and runbooks for any steps that target Azure (such as Azure Web App, Azure Cloud Service, Azure VM, or Azure Script steps).Affected if Any Azure-targeting steps exist in deployment or runbook processes.
-
Confirm verbose task logging is or was enabledCheck the Octopus server configuration for the default task log level setting, and review historical task logs for any Azure-related deployment or runbook runs.Affected if Verbose (Debug or Verbose) logging level is set, or verbose logs exist for Azure step executions.
-
Inspect task logs for credential exposureDownload and search historical verbose task logs from the Tasks > History section for Azure steps, looking for plaintext passwords or sensitive strings that may match Azure account credentials.Affected if Azure account passwords appear in cleartext within any verbose task logs.
You are affected if your Octopus Deploy version is between 2020.3.0 and 2020.3.3 inclusive or between 2020.4.0 and 2020.4.0 inclusive, AND you have Azure steps configured with verbose logging enabled, with passwords visible in task logs.
Generated from the published advisory. Verify against your own configuration.
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 data2020.3.4
Upgrade Octopus Deploy to version 2020.3.4 or 2020.4.1 or later. Additionally, review historical verbose task logs for any exposed credentials and rotate any compromised Azure account passwords.
