CVE-2025-61492 is a command injection vulnerability identified in the execute_command function of terminal-controller-mcp version 0.1.7. Command injection vulnerabilities occur when untrusted input is improperly sanitized and passed to a system shell or command interpreter, allowing attackers to execute arbitrary commands on the affected system. In this case, the vulnerability arises from the execute_command function, which processes input that can be manipulated by an attacker to inject malicious commands. Exploiting this vulnerability could allow an attacker to execute arbitrary code with the privileges of the application, potentially leading to full system compromise. The vulnerability was reserved in September 2025 and published in January 2026, but no CVSS score or patches have been released yet. No known exploits have been reported in the wild, which suggests it may be newly discovered or not yet weaponized. The affected software, terminal-controller-mcp, is typically used in terminal control or industrial automation contexts, which often have elevated security requirements. The lack of a CVSS score requires an assessment based on the nature of the vulnerability, which indicates a high severity due to the ability to execute arbitrary commands remotely without authentication or user interaction. This vulnerability poses a significant risk to systems running the affected version, especially if exposed to untrusted networks or users.

The impact of CVE-2025-61492 on European organizations could be severe, particularly for those relying on terminal-controller-mcp in industrial control systems, manufacturing environments, or critical infrastructure. Successful exploitation could lead to unauthorized command execution, resulting in data breaches, system manipulation, disruption of operations, or complete system takeover. This could compromise the confidentiality, integrity, and availability of critical systems. Given the potential for attackers to gain control over affected devices, organizations could face operational downtime, financial losses, regulatory penalties, and reputational damage. The lack of authentication requirements and ease of exploitation increase the risk of widespread impact if the vulnerable software is accessible from external or internal networks. European sectors such as energy, manufacturing, transportation, and utilities, which often use such terminal control software, are particularly at risk. The absence of known exploits provides a window for proactive defense but also means organizations must act quickly to mitigate potential future attacks.

1. Immediate mitigation should focus on restricting access to systems running terminal-controller-mcp 0.1.7, especially from untrusted networks, using network segmentation and firewall rules. 2. Monitor network traffic and system logs for unusual command execution patterns or unexpected input to the execute_command function. 3. Implement strict input validation and sanitization controls at the application level if source code or configuration changes are possible. 4. If feasible, disable or limit the functionality of the execute_command function until a patch is available. 5. Engage with the software vendor or community to obtain patches or updates addressing this vulnerability as soon as they are released. 6. Conduct thorough vulnerability scanning and penetration testing focused on command injection vectors within affected environments. 7. Educate system administrators and security teams about this vulnerability to ensure rapid detection and response. 8. Consider deploying application-layer firewalls or intrusion prevention systems capable of detecting and blocking command injection attempts targeting terminal-controller-mcp. 9. Maintain up-to-date backups and incident response plans to minimize damage in case of exploitation.
