CVE-2025-24977

Comprehensive Technical Analysis of CVE-2025-24977

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24977 CVSS Score: 9.1

The vulnerability in OpenCTI, an open cyber threat intelligence (CTI) platform, allows any user with the manage customizations capability to execute commands on the underlying infrastructure and access internal server-side secrets via misuse of web-hooks. This vulnerability is severe due to the potential for complete system compromise and further lateral movement within the infrastructure. The CVSS score of 9.1 indicates a critical severity level, necessitating immediate attention and remediation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Privilege Escalation: Users with manage customizations capability can escalate their privileges to gain root access within the container.
• Command Execution: Malicious users can execute arbitrary commands on the underlying infrastructure.
• Data Exfiltration: Access to internal server-side secrets can lead to data exfiltration and unauthorized access to sensitive information.

Exploitation Methods:

• Web-Hook Misuse: By manipulating web-hooks, attackers can inject malicious commands that are executed on the server.
• Container Escape: Gaining a root shell inside the container can potentially allow attackers to escape the container and compromise the host system.

3. Affected Systems and Software Versions

Affected Software:

• OpenCTI versions prior to 6.4.11

Affected Systems:

• Any infrastructure hosting OpenCTI versions prior to 6.4.11, including cloud environments, on-premises servers, and containerized deployments.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Upgrade OpenCTI to version 6.4.11 or later to mitigate the vulnerability.
• Access Control: Restrict the manage customizations capability to trusted users only.
• Monitoring: Implement monitoring and alerting for suspicious activities related to web-hooks and command execution.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• Least Privilege: Enforce the principle of least privilege for all user roles.
• Container Security: Implement robust container security measures, including isolation and monitoring.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of CVE-2025-24977 highlight the critical importance of securing CTI platforms, which are essential for threat intelligence sharing and analysis. The vulnerability underscores the need for:

• Enhanced Access Controls: Stricter access controls and role-based permissions.
• Container Security: Improved security practices for containerized applications.
• Incident Response: Robust incident response plans to quickly address and mitigate such vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• Root Cause: The vulnerability stems from insufficient validation and sanitization of inputs related to web-hooks, allowing command injection.
• Exploitation: Attackers can craft malicious web-hook payloads that execute arbitrary commands on the server.
• Impact: Successful exploitation results in a root shell within the container, potentially leading to further compromise of the host system and infrastructure.

Detection and Response:

• Log Analysis: Analyze logs for unusual command executions and web-hook activities.
• Intrusion Detection: Deploy intrusion detection systems (IDS) to monitor for suspicious activities.
• Patch Management: Ensure timely application of security patches and updates.

Conclusion: CVE-2025-24977 represents a critical vulnerability in OpenCTI that necessitates immediate remediation. Organizations using OpenCTI should prioritize upgrading to version 6.4.11 or later and implement robust security measures to prevent exploitation. The cybersecurity community should take note of this vulnerability to enhance the security of CTI platforms and containerized environments.
