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 versions 2018.8.4 to 2019.7.6, when a web request proxy is configured, an authenticated user (in certain limited special-characters circumstances) could trigger a deployment that writes the web request proxy password to the deployment log in cleartext. This is fixed in 2019.7.7. The fix was back-ported to LTS 2019.6.7 as well as LTS 2019.3.8.

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

In Octopus Deploy 2018.8.4-2019.7.6, when a web request proxy is configured with certain special-character circumstances, an authenticated user can trigger a deployment that writes the proxy password in cleartext to the deployment logs, resulting in credential exposure.

MitigationUpgrade to Octopus Deploy 2019.7.7 or later, or the backported LTS versions (2019.6.7 or 2019.3.8). Review existing deployment logs for exposed proxy passwords and rotate compromised credentials.

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. Check Octopus Server version
    Navigate to Configuration > About in the Octopus UI, or run 'Octopus.Server version' from the command line if you have server access
    Affected if version is 2018.8.4 through 2019.7.6 inclusive (vulnerable range)
  2. Confirm web request proxy with authentication is configured
    Navigate to Infrastructure > Proxies in the Octopus UI, or query the configuration database for proxy entries where authentication is enabled
    Affected if a web request proxy with username/password authentication is configured and in use
  3. Search deployment logs for exposed proxy credentials
    Review recent and historical deployment task logs, searching for the proxy username or any plaintext password patterns that may have been written during deployments
    Affected if proxy passwords appear in cleartext within any deployment logs

You are affected if running Octopus Server 2018.8.4-2019.7.6 with a configured proxy that uses authentication, and deployment logs contain plaintext proxy passwords.

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 data
Upgrade available Upgrade to a release after 2019.7.6
Interim mitigation

Upgrade to Octopus Deploy 2019.7.7 or later, or the backported LTS versions (2019.6.7 or 2019.3.8). Review existing deployment logs for exposed proxy passwords and rotate compromised credentials.
