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 Tentacle versions 3.0.8 to 5.0.0, when a web request proxy is configured, an authenticated user (in certain limited OctopusPrintVariables circumstances) could trigger a deployment that writes the web request proxy password to the deployment log in cleartext. This is fixed in 5.0.1. The fix was back-ported to 4.0.7.

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

Octopus Tentacle versions 3.0.8 through 5.0.0 contain a cleartext password storage vulnerability where web request proxy passwords are written in cleartext to deployment logs when certain OctopusPrintVariables conditions are met and a deployment is triggered by an authenticated user.

MitigationUpgrade Octopus Tentacle to version 5.0.1 or 4.0.7 (or later), and audit existing deployment logs for any exposed proxy passwords that should be rotated and securely regenerated.

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 Tentacle version
    Run 'Tentacle --version' or check the tentacle installation directory for version information. Compare the installed version to the affected range 3.0.8 through 5.0.0.
    Affected if Installed version is 3.0.8, 3.0.9, 3.0.10, 3.0.11, 3.0.12, 3.0.13, 3.0.14, 3.0.15, 3.0.16, 3.0.17, 3.1.0, 3.1.1, 3.1.2, 3.1.3, 3.2.0, 3.2.1, 3.2.2, 3.2.3, 3.2.4, 3.2.5, 3.2.6, 3.2.7, 3.2.8, 3.2.9, 3.2.10, 3.2.11, 3.2.12, 3.2.13, 3.2.14, 3.2.15, 3.2.16, 3.2.17, 3.2.18, 3.2.19, 3.2.20, 3.2.21, 3.2.22,
  2. Check Octopus Server version
    Run 'Octopus.Server --version' or check the server installation for version information. Compare the installed version to the affected range 3.0.8 through 2019.7.6.
    Affected if Installed version is between 3.0.8 and 2019.7.6 inclusive.
  3. Inspect deployment logs for cleartext proxy passwords
    Search deployment log files for patterns that may indicate proxy passwords. Look for log entries containing proxy configuration with password fields in cleartext, particularly around OctopusPrintVariables output. Check the deployment logs directory (typically under the Octopus data folder) for any deployments that occurred after the Octopus installation.
    Affected if Deployment logs contain any web request proxy passwords written in cleartext.
  4. Verify if web request proxy is configured
    Check Octopus configuration for any configured web request proxy settings. This can be done through the Octopus web portal under Infrastructure > Proxies, or by inspecting the Octopus configuration files. Look for proxy configurations that include a password field.
    Affected if A web request proxy is configured with a stored password, and the deployment logs have been generated with OctopusPrintVariables enabled.
  5. Check for OctopusPrintVariables conditions in deployments
    Review deployment processes and variable sets to determine if OctopusPrintVariables is enabled or if conditions exist that trigger verbose variable printing during deployments. Check the deployment process steps and any custom scripting that enables verbose variable output.
    Affected if OctopusPrintVariables is enabled or conditions are met that cause sensitive variables including proxy passwords to be written to deployment logs.

You are affected if you are running Octopus Server 3.0.8-2019.7.6 or Octopus Tentacle 3.0.8-5.0.0, have a web request proxy with a password configured, and have deployment logs that may contain cleartext proxy passwords due to OctopusPrintVariables conditions.
