CVE-2020-25825
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 3.1.0 to 2020.4.0, certain scripts can reveal sensitive information to the user in the task logs.
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 confidenceOctopus Deploy versions 3.1.0 through 2020.4.0 contain an information disclosure vulnerability where certain deployment scripts can cause sensitive information (such as variables, secrets, or credentials) to be written to task logs, potentially visible to users who should not have access to that data.

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.
-
Determine the installed Octopus Deploy versionLog into the Octopus Deploy web UI, click Help in the top navigation, and select About. Alternatively, open Octopus Manager or check the Windows service properties for the version number.Affected if The version displayed falls within the range 3.1.0 through 2020.4.0 (for example, 2020.1.5, 2019.12.0, 3.15.0).
-
Confirm version from command lineIf you have the Octopus Server executable, run 'Octopus.Server version' from the installation directory, or query the API endpoint /api/about.Affected if The returned version matches any version from 3.1.0 up to and including 2020.4.0.
-
Verify deployment processes using sensitive variablesReview your deployment processes in the Octopus UI under Library > Step Templates and your Project processes. Identify steps that use variable substitution, especially with variable types marked as sensitive (octopus variable type 'Sensitive').Affected if You have deployment steps that reference sensitive variables, secrets, or credentials, and the Octopus version is within the affected range.
You are affected if your installed Octopus Deploy version is 3.1.0 or higher through 2020.4.0 inclusive, and you use sensitive variables or secrets in deployment scripts.

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 Octopus Deploy to a version after 2020.4.0. Review existing task logs for any accidentally exposed sensitive information and rotate any credentials that may have been disclosed.
