CVE-2022-25264
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 2021.2.3, environment variables of the "password" type 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 before 2021.2.3, environment variables marked as 'password' type could be inadvertently written to logs, allowing unauthorized users with log access to potentially retrieve sensitive credentials.

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 the installed TeamCity versionAccess the TeamCity administration interface and navigate to 'About' page, or check the version from the TeamCity server start-up logs. Compare this version number to the affected range (versions before 2021.2.3).Affected if The installed version is 2021.2.2 or earlier, or any version less than 2021.2.3.
-
Determine if password-type environment variables are configuredIn the TeamCity web interface, go to 'Administration' > 'Environment Variables'. Review the list of defined environment variables and identify any that are marked with type 'password' or 'secure value'.Affected if Password-type or secure-type environment variables are defined in TeamCity.
-
Examine TeamCity logs for exposed credentialsAccess the TeamCity logs directory (typically found in <TeamCity_home>/logs/). Open recent build and server logs and search for patterns that may contain the names of your password-type environment variables followed by their values. Use grep or text search to look for occurrences of these variable names in the logs.Affected if Log files contain the literal values of password-type environment variables (not just variable names).
A system is affected if it runs TeamCity version before 2021.2.3 AND has password-type environment variables configured AND those credentials appear in plaintext in logs.

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 · scoped2021.2.3
Upgrade to TeamCity 2021.2.3 or later. Additionally, rotate any credentials that may have been exposed in logs as a precautionary measure.
2021.2.3
- 1. Back up your TeamCity installation, database, and configuration before upgrading
- 2. Download TeamCity version 2021.2.3 or later from the official JetBrains website (www.jetbrains.com/teamcity/download)
- 3. Follow the official TeamCity upgrade instructions to install the new version
- 4. After upgrade, verify that password-type environment variables are no longer being logged in build logs
- 5. Review build logs to confirm the fix is effective
