CVE-2024-41828
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 2024.07 comparison of authorization tokens took non-constant time
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 confidenceTeamCity before version 2024.07 had a timing attack vulnerability in authorization token comparison. The token comparison logic did not use constant-time comparison, meaning the response time varied based on how many characters of the token matched before finding a difference. This could allow attackers to infer valid token values by measuring timing differences.

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 TeamCity server versionLog into the TeamCity web interface as an administrator. Navigate to the 'Administration' section and click 'Server Configuration'. The version number is displayed on this page under 'TeamCity Version'. Alternatively, you can check the version by viewing the 'about' page or checking the server startup logs.Affected if The displayed version is earlier than 2024.07 (for example, 2024.06, 2024.04, 2023.x, etc.)
-
Check TeamCity version via command lineIf you have direct access to the TeamCity server, check the version from the command line. Navigate to the TeamCity home directory and look for a version file, or execute: cd <TeamCity_home>/bin and run the version check script if available.Affected if The command output or version file shows a version number below 2024.07
-
Verify authentication token usageIn the TeamCity web UI under 'Administration' > 'User Management' > 'Tokens', check if any API access tokens have been created. The timing attack vulnerability affects any instance using token-based authentication.Affected if The server uses API tokens for authentication and is running a TeamCity version below 2024.07
A TeamCity server is affected by CVE-2024-41828 if it is running any version prior to 2024.07 and uses token-based authentication for API or user access.

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.
dbcve · scoped2024.07
Upgrade TeamCity to version 2024.07 or later, which implements constant-time token comparison.
2024.07
- Create a complete backup of your TeamCity installation including the <TeamCity home> directory and database
- Stop the TeamCity server
- Download TeamCity 2024.07 or later from the official JetBrains website (www.jetbrains.com)
- Install the upgrade following JetBrains standard upgrade procedures for your deployment type
- Start the TeamCity server
- Verify the server is running correctly and all services are operational
- Confirm the timing attack vulnerability is remediated by verifying token comparisons now use constant-time comparison
