CVE-2019-18366
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 JetBrains TeamCity before 2019.1.2, secure values could be exposed to users with the "View build runtime parameters and data" permission.
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 TeamCity versions prior to 2019.1.2, secure values such as passwords, tokens, and other sensitive parameters were incorrectly exposed to users who possessed the 'View build runtime parameters and data' permission. This allowed unauthorized viewing of sensitive credential data that should have been masked or hidden, constituting an information disclosure vulnerability.

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 installed TeamCity versionNavigate to Administration > Diagnostics or view the version on the login page/footer. Compare the version number to 2019.1.2.Affected if Version is earlier than 2019.1.2 (e.g., 2019.1.1, 2019.1, 2018.x)
-
Identify users with the View build runtime parameters permissionGo to Administration > User Management > Roles or Groups. Search for the permission 'View build runtime parameters and data' and list all users or groups assigned this role.Affected if Any user account or group is assigned a role containing the 'View build runtime parameters and data' permission
-
Review build configurations for secure parametersNavigate to a build configuration > Parameters tab. Look for parameters with type 'password' or 'secure' that contain actual values stored.Affected if Build configurations contain password, token, or other secure-type parameters with configured values
You are affected if your TeamCity version is before 2019.1.2 AND you have users with the 'View build runtime parameters and data' permission AND your build configurations contain secure-type parameters.
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 data2019.1.2
Upgrade TeamCity to version 2019.1.2 or later, which properly restricts secure values from being displayed to users with only the 'View build runtime parameters and data' permission.
