CVE-2024-47160 - Unauthorized Access to Global App Config Data in JetBrains YouTrack before 2024.3.44799

In this post, we will delve into the details of CVE-2024-47160, a security vulnerability discovered in JetBrains YouTrack before 2024.3.44799. This vulnerability allows unauthorized users to gain access to global app configuration data without the necessary permissions. Understanding this vulnerability can help developers build a more secure environment for their YouTrack applications and respond effectively to potential threats.

Vulnerability Details

CVE-2024-47160 highlights a severe information disclosure vulnerability that affects JetBrains YouTrack versions before 2024.3.44799. Attackers can exploit this vulnerability to access sensitive data from the global app configuration.The unauthorized access can lead to the disclosure of sensitive information, which can cause significant harm to organizations using the affected application.

To learn more about this vulnerability, you can visit the official JetBrains security bulletin and the CVE details page.

Code Snippet

Below is a code snippet illustrating the vulnerability in JetBrains YouTrack before 2024.3.44799. This particular snippet is only a representation of the potential vulnerable part, as the actual codebase behind JetBrains YouTrack is proprietary.

def get_global_config(request):
    # Missing permission check
    config_data = fetch_global_config_data()
    return jsonify(config_data)

As seen in the code snippet above, there is no permission check performed before accessing and returning the global app configuration data. This oversight effectively allows any user, even those without appropriate permissions, to access sensitive configuration data.

Exploiting the Vulnerability

To exploit this vulnerability, an attacker only needs to send a specially crafted request to the affected application endpoint. Upon receiving the request, the application will return the global config data without verifying the user's permissions.

For example, an attacker could send an HTTP request like the following

GET /api/global/config HTTP/1.1
Host: youtrack.example.com
User-Agent: attacker
Accept: */*

As a result, the application would return the global config data in JSON format, which could include sensitive information, such as API keys or confidential business data.

Mitigation and Solution

To address this vulnerability, JetBrains has released a security update, version 2024.3.44799, which contains a fix for the security issue. Developers using affected versions of JetBrains YouTrack should update their software immediately to avoid exposing sensitive data to attackers.

If you're unable to update, you can implement the following workarounds to mitigate potential exploits:

- Restrict access to the global app configuration data endpoints to a limited set of IP addresses or trusted networks.
- Add custom permission checks to the affected endpoints to ensure that only authorized users can access sensitive data.

It is essential to remain vigilant and up-to-date with security practices to mitigate the impact of such vulnerabilities on your application.

Conclusion

CVE-2024-47160 is a critical security vulnerability in JetBrains YouTrack that allows unauthorized access to sensitive global app configuration data. Developers must take action to ensure that their YouTrack applications are secure by updating to the latest version and implementing additional security measures as needed. By staying informed about security vulnerabilities and keeping your software up-to-date, you can better protect your application and its data from potential threats.
