CVE-2019-15037
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 · uneditedAn issue was discovered in JetBrains TeamCity 2018.2.4. It had several XSS vulnerabilities on the settings pages. The issues were fixed in TeamCity 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 · moderate confidenceMultiple cross-site scripting (XSS) vulnerabilities existed in JetBrains TeamCity 2018.2.4 on settings pages, allowing authenticated users to inject malicious scripts that could be executed in other users' browsers. The CVSS 6.1 score reflects a network-exploitable issue requiring user interaction, with scope changes due to the XSS impacting other components.

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.
-
Identify TeamCity installation and versionAccess the TeamCity web interface and check the version number, typically visible on the login page or in the Administration > Global Settings page. The version is displayed as 'TeamCity 2018.2.4' or similar.Affected if The installed version is exactly 2018.2.4 (no other versions are affected)
-
Confirm authenticated access to settings pagesLog in as an authenticated user and navigate to any settings page such as Administration > Global Settings, Project Settings, or Build Configuration settings.Affected if User has authenticated access to TeamCity settings pages
-
Verify XSS vulnerability presence on settings pagesOn any settings page, inspect the HTML source or form fields to identify input points that reflect user-supplied data back into the page without proper sanitization.Affected if Settings page inputs reflect unsanitized user input in the rendered HTML
You are affected only if your TeamCity installation is version exactly 2018.2.4 and you have authenticated users who can access settings pages where the XSS could be triggered.

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 to TeamCity 2019.1 or later to remediate the XSS vulnerabilities. After upgrading, verify that all settings pages and related functionality operate correctly.
