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
In JetBrains TeamCity before 2024.12 backup file exposed user credentials and session cookies

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 versions prior to 2024.12, the backup functionality exposes sensitive user credentials and session cookies within backup files. An attacker with access to these backup files could extract valid user credentials and active session tokens for privilege escalation or session hijacking.

MitigationUpgrade to TeamCity 2024.12 or later to resolve the backup exposure issue. Review and rotate any credentials that may have been included in backups created with vulnerable versions.

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 TeamCity version
    Access the TeamCity administration interface and navigate to 'About' page, or check the buildServer.properties file for the version number
    Affected if The installed version is earlier than 2024.12
  2. Locate backup files
    Check the TeamCity data directory for .zip or .tar.gz backup files, typically found in the 'backups' subdirectory or the directory specified in server configuration
    Affected if Backup files exist and were created with a TeamCity version earlier than 2024.12
  3. Inspect backup contents for credentials
    Extract a backup file and search for stored user credentials, API keys, or authentication tokens within the backup archive - look in configuration files or user data directories within the extracted backup
    Affected if The backup archive contains plaintext or weakly protected user credentials, API tokens, or authentication configuration files
  4. Check for session cookies in backups
    Examine the backup file for session-related data, including cookie files, session tokens, or remember-me tokens stored for user authentication
    Affected if The backup contains session cookies, remember-me tokens, or other session-related authentication artifacts
  5. Review backup file access controls
    Verify who has access to backup files - check file permissions and confirm if unauthorized users or processes could read backup archives
    Affected if Backup files are accessible to users or processes that should not have access to sensitive authentication data

A user is affected if running TeamCity version earlier than 2024.12 and has backup files that may contain exposed credentials or session cookies accessible to unauthorized parties.

Upgrade available Upgrade to 2024.12 or later
Fixed in 2024.12
Interim mitigation

Upgrade to TeamCity 2024.12 or later to resolve the backup exposure issue. Review and rotate any credentials that may have been included in backups created with vulnerable versions.

Recommended fix Moderate confidence

TeamCity 2024.12

  1. Upgrade TeamCity to version 2024.12 or later to remediate the backup file credential exposure vulnerability
  2. After upgrading, rotate all user credentials and session tokens that may have been present in backups created before the update
  3. If using automated backup systems, verify that new backups no longer contain exposed credentials
  4. Review access controls on backup files to ensure they are stored securely
