CVE-2024-25675

Comprehensive Technical Analysis of CVE-2024-25675

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-25675 CVSS Score: 9.8

The vulnerability in question affects the Malware Information Sharing Platform (MISP) before version 2.4.184. The issue arises because a client does not need to use the POST method to start an export generation process, which is typically a security measure to prevent unauthorized actions. This vulnerability is rated with a CVSS score of 9.8, indicating a critical severity level. The high score is due to the potential for unauthorized access, data manipulation, and the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves exploiting the lack of enforcement of the POST method for starting an export generation process. An attacker could potentially:

• Unauthorized Data Export: Initiate data export processes without proper authorization, leading to unauthorized access to sensitive information.
• Data Manipulation: Manipulate the export process to inject malicious data or corrupt the exported files.
• Denial of Service (DoS): Overload the system by repeatedly triggering the export process, leading to resource exhaustion and service disruption.

Exploitation methods could include:

• Direct HTTP Requests: Sending GET requests instead of POST requests to the affected endpoints.
• Automated Scripts: Using automated scripts to repeatedly trigger the export process, causing a DoS condition.

3. Affected Systems and Software Versions

The vulnerability affects MISP versions before 2.4.184. Specifically, the affected components are:

• app/Controller/JobsController.php
• app/View/Events/export.ctp

Users running MISP versions prior to 2.4.184 are at risk and should upgrade to the latest version to mitigate this vulnerability.

4. Recommended Mitigation Strategies

To mitigate the risk associated with CVE-2024-25675, the following strategies are recommended:

• Upgrade to the Latest Version: Upgrade MISP to version 2.4.184 or later, which includes the necessary patches to enforce the use of the POST method for export generation.
• Access Controls: Implement strict access controls to limit who can initiate export processes.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to unauthorized export attempts.
• Rate Limiting: Implement rate limiting to prevent abuse of the export functionality.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of CVE-2024-25675 highlight the importance of enforcing proper HTTP methods for sensitive operations. This vulnerability underscores the need for:

• Strict Adherence to Security Best Practices: Ensuring that sensitive operations are protected by enforcing the correct HTTP methods.
• Regular Software Updates: Keeping software up to date to mitigate known vulnerabilities.
• Proactive Monitoring: Continuously monitoring systems for unusual activities that could indicate an exploitation attempt.

6. Technical Details for Security Professionals

Affected Code:

• JobsController.php: The controller handling job-related operations, including export generation.
• export.ctp: The view template responsible for rendering the export process.

Patch Details:

• The patch introduced in version 2.4.184 enforces the use of the POST method for starting the export generation process. This ensures that only authorized and properly formatted requests can initiate the export.
