CVE-2025-6237

Comprehensive Technical Analysis of CVE-2025-6237

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-6237 CVSS Score: 9.8

The vulnerability in invokeai version v6.0.0a1 and below allows for path traversal and arbitrary file deletion via the GET /api/v1/images/download/{bulk_download_item_name} endpoint. This vulnerability is critical due to its high impact on confidentiality, integrity, and availability. The CVSS score of 9.8 indicates a severe risk, necessitating immediate attention and mitigation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Path Traversal: Attackers can manipulate the bulk_download_item_name parameter to traverse directories and access files outside the intended directory.
• Arbitrary File Deletion: By exploiting the path traversal vulnerability, attackers can delete critical system files, including SSH keys, databases, and configuration files.

Exploitation Methods:

• Manipulating Filename Arguments: Attackers can craft specific filenames to navigate through the directory structure and access or delete sensitive files.
• Automated Scripts: Attackers may use automated scripts to systematically exploit the vulnerability, targeting multiple endpoints and files.

3. Affected Systems and Software Versions

Affected Software:

• invokeai version v6.0.0a1 and below

Affected Systems:

• Any system running the vulnerable versions of invokeai, particularly those with the /api/v1/images/download/{bulk_download_item_name} endpoint exposed to the internet.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to a patched version of invokeai that addresses this vulnerability.
• Endpoint Restriction: Temporarily disable the /api/v1/images/download/{bulk_download_item_name} endpoint until a patch is applied.
• Access Control: Implement strict access controls to limit exposure of the vulnerable endpoint.

Long-Term Mitigations:

• Input Validation: Ensure robust input validation to prevent path traversal attacks.
• Least Privilege: Apply the principle of least privilege to limit the permissions of the application running invokeai.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-6237 highlights the ongoing challenge of securing web applications against path traversal and file manipulation vulnerabilities. This vulnerability underscores the importance of:

• Secure Coding Practices: Ensuring developers are trained in secure coding practices to avoid common vulnerabilities.
• Proactive Patching: Maintaining a proactive approach to patching and updating software to mitigate known vulnerabilities.
• Incident Response: Having a robust incident response plan to quickly address and mitigate vulnerabilities when they are discovered.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: GET /api/v1/images/download/{bulk_download_item_name}
• Parameter: bulk_download_item_name
• Exploit: Manipulating the bulk_download_item_name parameter to include directory traversal sequences (e.g., ../../etc/passwd).

Detection Methods:

• Log Analysis: Monitor logs for unusual file access patterns or repeated attempts to access system files.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious activity related to path traversal and file deletion attempts.

Mitigation Steps:

1. Update Software: Ensure all instances of invokeai are updated to a version that addresses CVE-2025-6237.
2. Implement WAF: Use a Web Application Firewall (WAF) to block path traversal attempts.
3. Regular Patching: Establish a regular patching schedule to ensure all software is up-to-date with the latest security patches.

Conclusion: CVE-2025-6237 represents a significant risk to systems running vulnerable versions of invokeai. Immediate mitigation through patching and access control is essential to protect against potential exploitation. Long-term strategies, including secure coding practices and regular security audits, are crucial for maintaining a robust cybersecurity posture.
