CVE-2024-50574
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 YouTrack before 2024.3.47707 potential ReDoS exploit was possible via email header parsing in Helpdesk functionality
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 confidenceA Regular Expression Denial of Service (ReDoS) vulnerability exists in JetBrains YouTrack's Helpdesk email header parsing functionality. By sending specially crafted email headers, an attacker can cause excessive regex backtracking, leading to denial of service. The vulnerability affects versions prior to 2024.3.47707.

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 installed YouTrack versionAccess the YouTrack administration interface and navigate to the About section, or check the version displayed on the login page. Alternatively, inspect the youtrack.jar file properties if deployed on-premises.Affected if The installed version number is lower than 2024.3.47707 (for example, 2024.2.x or earlier).
-
Confirm Helpdesk module is activeLog into YouTrack as an administrator and navigate to the Settings or Modules section to verify if the Helpdesk feature is enabled and configured.Affected if Helpdesk is enabled and configured to receive emails.
-
Check email processing configurationIn YouTrack administration, review the Helpdesk email settings to confirm inbound email processing is configured, particularly any custom email header parsing rules.Affected if Inbound email processing is enabled for Helpdesk, making the service exposed to crafted email headers.
A YouTrack instance is affected if it runs a version prior to 2024.3.47707 AND has the Helpdesk module enabled with email processing configured.
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 · scoped2024.3.47707
Upgrade YouTrack to version 2024.3.47707 or later. If immediate upgrade is not possible, consider implementing rate limiting or input validation on email processing endpoints as a temporary mitigation.
2024.3.47707 or later stable release
- Ensure you have a complete backup of your YouTrack database and configuration files before upgrading
- Stop the YouTrack service to prevent data inconsistencies during the upgrade
- Download YouTrack version 2024.3.47707 or a later stable release from the official JetBrains website (www.jetbrains.com)
- Apply the upgrade by running the installer or applying the new version to your existing installation
- After upgrade completion, verify that YouTrack starts successfully
- Test the Helpdesk functionality to confirm the email header parsing works correctly and the ReDoS vulnerability is mitigated
