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
An issue was discovered in JetBrains TeamCity 2018.2.4. A TeamCity Project administrator could execute any command on the server machine. The issue was fixed in TeamCity 2018.2.5 and 2019.1.

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 JetBrains TeamCity 2018.2.4, a Project administrator could execute arbitrary commands on the underlying server due to insufficient access control enforcement, allowing privilege escalation from project-level permissions to full system command execution.

MitigationUpgrade TeamCity to version 2018.2.5, 2019.1, or later to remediate this 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed TeamCity version
    Locate the TeamCity version number via the web interface (typically shown in the footer of any TeamCity page) or in the TeamCity configuration files or logs
    Affected if The installed version is 2018.2.4 exactly
  2. Determine if project administrators exist
    Check if any user or group has been granted the Project Administrator role within any project in TeamCity. This can be viewed in the Administration > Users/Groups section under project access permissions.
    Affected if There are users or groups assigned the Project Administrator role for any project in the system
  3. Verify if build features allowing command execution are accessible
    Check if Project Administrator users can configure build steps or build features. Specifically, look for the presence of build runners that allow shell command execution (such as Command Line, PowerShell, or similar runners) within any project.
    Affected if Project Administrators have the ability to create or modify build configurations with command execution capabilities

A user is affected if they are running TeamCity version 2018.2.4 and have any Project Administrator role configured, allowing that role to potentially execute arbitrary commands on the server.

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.
