CVE-2025-11202

Comprehensive Technical Analysis of CVE-2025-11202

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-11202 CVSS Score: 9.8

The vulnerability in question is a Command Injection Remote Code Execution (RCE) flaw in the resolveCommandPath method of the win-cli-mcp-server. This vulnerability allows remote attackers to execute arbitrary code without requiring authentication. The high CVSS score of 9.8 indicates a critical severity due to the potential for complete system compromise, high impact on confidentiality, integrity, and availability, and the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can send specially crafted input to the resolveCommandPath method, which is then used in a system call without proper validation.
• Network-Based Attacks: Since authentication is not required, attackers can exploit this vulnerability over the network, making it a prime target for automated scanning and exploitation tools.

Exploitation Methods:

• Command Injection: By injecting malicious commands into the user-supplied string, an attacker can execute arbitrary code on the affected system.
• Privilege Escalation: If the service runs with elevated privileges, the attacker can gain higher-level access to the system.

3. Affected Systems and Software Versions

Affected Software:

• win-cli-mcp-server versions prior to the patch commit 521b4a34190d03bde7d433d213c36357181a6d09.

Affected Systems:

• Any system running the vulnerable versions of win-cli-mcp-server, including Windows servers and workstations where this service is deployed.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the patch provided in the commit 521b4a34190d03bde7d433d213c36357181a6d09 to mitigate the vulnerability.
• Network Segmentation: Isolate affected systems from the network to prevent remote exploitation.
• Access Controls: Implement strict access controls and network firewalls to limit exposure.

Long-Term Strategies:

• Input Validation: Ensure all user inputs are properly validated and sanitized before being used in system calls.
• Least Privilege: Run services with the least privilege necessary to minimize the impact of potential exploits.
• Regular Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery and exploitation of CVE-2025-11202 highlight the critical importance of input validation and secure coding practices. This vulnerability underscores the need for:

• Enhanced Security Training: Developers and security professionals must be trained to recognize and mitigate command injection vulnerabilities.
• Proactive Patch Management: Organizations must have robust patch management processes to quickly apply security updates.
• Increased Awareness: The cybersecurity community should be more aware of the risks associated with unvalidated user inputs, especially in network-facing services.

6. Technical Details for Security Professionals

Vulnerability Details:

• Root Cause: The resolveCommandPath method in win-cli-mcp-server does not properly validate user-supplied input before using it in a system call.
• Exploitation: An attacker can inject malicious commands into the input, leading to arbitrary code execution.

Detection and Response:

• Log Analysis: Monitor system logs for unusual command executions or unexpected system calls.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious network traffic patterns indicative of command injection attempts.
• Incident Response: Have an incident response plan in place to quickly identify, contain, and remediate any successful exploitation attempts.
