CVE-2025-64709

Comprehensive Technical Analysis of CVE-2025-64709

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-64709 CVSS Score: 9.6

The vulnerability in question is a Server-Side Request Forgery (SSRF) in the Typebot webhook block (HTTP Request component) functionality. This vulnerability allows authenticated users to make arbitrary HTTP requests from the server, potentially leading to unauthorized access to sensitive resources. The severity of this vulnerability is rated as critical (CVSS Score: 9.6) due to the potential for complete compromise of the Kubernetes cluster and associated AWS infrastructure.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Authenticated Users: The vulnerability requires the attacker to be authenticated, which means they need valid credentials to access the Typebot application.
• Custom Header Injection: The attacker can inject custom headers to bypass IMDSv2 protection, allowing them to access the AWS Instance Metadata Service (IMDS).

Exploitation Methods:

• SSRF Exploitation: The attacker can craft HTTP requests to internal services, including the AWS IMDS, to extract temporary AWS IAM credentials.
• Credential Extraction: Once the attacker gains access to the IMDS, they can extract temporary AWS IAM credentials for the EKS node role.
• Cluster Compromise: With the extracted credentials, the attacker can gain control over the Kubernetes cluster and associated AWS infrastructure, leading to a complete compromise.

3. Affected Systems and Software Versions

Affected Software:

• Typebot versions prior to 3.13.1

Affected Systems:

• Any system running the vulnerable versions of Typebot, particularly those integrated with AWS infrastructure and Kubernetes clusters.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade to Version 3.13.1: Immediately upgrade to Typebot version 3.13.1 or later, which includes the fix for this vulnerability.
• Restrict Access: Ensure that only trusted users have access to the Typebot application and limit their permissions as much as possible.

Long-Term Mitigations:

• Network Segmentation: Implement network segmentation to isolate critical services and reduce the attack surface.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities promptly.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of this vulnerability highlight the critical importance of securing webhook functionalities and ensuring proper authentication and authorization mechanisms. The potential for complete compromise of Kubernetes clusters and AWS infrastructure underscores the need for robust security practices in cloud environments. This incident serves as a reminder for organizations to prioritize security in their DevOps pipelines and continuously monitor for vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• SSRF Mechanism: The SSRF vulnerability in the Typebot webhook block allows attackers to send HTTP requests to internal services, including the AWS IMDS.
• IMDSv2 Bypass: The attacker can inject custom headers to bypass IMDSv2 protection, which is designed to prevent unauthorized access to the IMDS.
• Credential Extraction: By accessing the IMDS, the attacker can retrieve temporary AWS IAM credentials, which can be used to gain control over the Kubernetes cluster and associated AWS resources.

Detection and Response:

• Anomaly Detection: Implement anomaly detection mechanisms to identify unusual HTTP requests and access patterns.
• Incident Response: Develop and maintain an incident response plan to quickly address and mitigate any security breaches.
• Patch Management: Ensure that all software dependencies are regularly updated and patched to mitigate known vulnerabilities.

Conclusion: CVE-2025-64709 represents a critical vulnerability that underscores the importance of securing webhook functionalities and ensuring robust authentication mechanisms. Organizations should prioritize upgrading to the patched version of Typebot and implement comprehensive security measures to protect their cloud infrastructure.
