EUVD-2025-36708

Comprehensive Technical Analysis of EUVD-2025-36708

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-36708 affects the win-cli-mcp-server software, specifically within the resolveCommandPath method. This flaw allows for command injection, leading to remote code execution (RCE) without the need for authentication. The issue arises from insufficient validation of user-supplied input before it is used in a system call.

Severity Evaluation:

• CVSS Base Score: 9.8
• CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high CVSS score indicates a critical vulnerability due to the following factors:

• Attack Vector (AV:N): Network-based attack, meaning it can be exploited remotely.
• Attack Complexity (AC:L): Low complexity, indicating that the attack is relatively easy to execute.
• Privileges Required (PR:N): No privileges are required to exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required.
• Scope (S:U): The vulnerability does not change the security scope.
• Confidentiality (C:H), Integrity (I:H), Availability (A:H): High impact on all three CIA triad components.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Code Execution (RCE): An attacker can send crafted input to the resolveCommandPath method, leading to arbitrary code execution.
• Command Injection: The lack of input validation allows attackers to inject malicious commands that are executed by the system.

Exploitation Methods:

• Network-Based Exploits: Attackers can exploit this vulnerability over the network without needing to authenticate.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable installations and exploit them en masse.

3. Affected Systems and Software Versions

Affected Software:

• Product: win-cli-mcp-server
• Version: 215f0cc4ed0c21ce028246c19ebfa32f5b3f7848

Vendor:

• Vendor Name: win-cli-mcp-server

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor.
• Input Validation: Ensure that all user-supplied input is properly validated and sanitized before being used in system calls.
• Access Controls: Implement strict access controls to limit exposure to the vulnerable service.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Network Segmentation: Segment the network to isolate critical systems and reduce the attack surface.
