CVE-2023-34223
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 2023.05 parameters of the "password" type from build dependencies could be logged in some cases
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 JetBrains TeamCity versions before 2023.05, password-type parameters from build dependencies could be inadvertently written to logs. This could expose sensitive credentials stored in password parameters to unauthorized parties with access to TeamCity log files.

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 versionAccess the TeamCity administration UI, go to 'Administration' > 'Server Configuration', or query the server's buildConfig.properties file. Locate the version number displayed.Affected if The installed version is any release earlier than 2023.05 (for example, 2023.04.x, 2022.x, or earlier).
-
Identify build configurations with dependencies using password parametersReview all build configurations that have dependencies on other projects or builds. For each dependency, check whether the dependency passes password-type parameters to the downstream build configuration.Affected if Build configurations exist that use build dependencies and those dependencies pass password-type parameters to the consuming build.
-
Examine build logs for credential exposureNavigate to the TeamCity data directory, locate the logs folder, and search build log files for patterns matching password parameter names or their values. Use grep or similar search tools to scan .log files for occurrences of parameter names marked as 'password' type.Affected if Log files contain plaintext passwords or password parameter values from build dependency configurations.
You are affected if your TeamCity version is below 2023.05 and you have build dependencies that pass password-type parameters, with those credentials potentially visible in build logs.
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.
dbcve · scoped2023.05
Upgrade TeamCity to version 2023.05 or later to remediate this vulnerability. Review existing logs for any inadvertent password exposure as a precautionary measure.
2023.05
- Back up the TeamCity data directory and database before upgrading
- Download TeamCity 2023.05 or later from the official JetBrains website (www.jetbrains.com/teamcity/download)
- Stop the TeamCity server service
- Run the TeamCity installer/upgrade on the server
- Follow the installation wizard to complete the upgrade
- Start the TeamCity server service
- Log in to TeamCity and verify the build configuration works correctly
- Confirm that password-type parameters are no longer logged in build logs
