CVE-2025-61492 identifies a critical command injection vulnerability in the execute_command function of terminal-controller-mcp version 0.1.7. This vulnerability arises due to insufficient sanitization of user-supplied input before it is passed to system-level command execution functions, classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). An attacker can craft malicious input that gets executed directly by the underlying operating system shell, enabling arbitrary command execution with the privileges of the affected application. The vulnerability requires no authentication (PR:N), no user interaction (UI:N), and can be exploited remotely over the network (AV:N). The CVSS 3.1 base score of 10 reflects the highest severity, with complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H) and a scope change (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. No patches or fixes have been published yet, and no known exploits are reported in the wild, but the ease of exploitation and impact make it a critical threat. The affected software, terminal-controller-mcp, is typically used in terminal management and control systems, which may be integrated into industrial or enterprise environments. Attackers exploiting this vulnerability could gain full control over affected systems, potentially leading to data breaches, system manipulation, or denial of service.

For European organizations, the impact of CVE-2025-61492 is severe. Exploitation can lead to full system compromise, allowing attackers to steal sensitive data, disrupt operations, or pivot within networks to escalate attacks. Industries relying on terminal-controller-mcp for managing critical infrastructure or industrial control systems face heightened risks, including operational downtime and safety hazards. The vulnerability's remote and unauthenticated nature means attackers can launch attacks from anywhere, increasing exposure. Given Europe's strong regulatory environment around data protection (e.g., GDPR), breaches resulting from this vulnerability could also lead to significant legal and financial penalties. Additionally, disruption in sectors like manufacturing, energy, or transportation could have cascading effects on supply chains and public services. The lack of available patches further exacerbates the risk, necessitating immediate defensive measures to prevent exploitation.

1. Immediately restrict network access to the terminal-controller-mcp service using firewalls or network segmentation to limit exposure to trusted hosts only. 2. Implement strict input validation and sanitization on all inputs passed to the execute_command function, ensuring that special characters and command delimiters are neutralized or rejected. 3. Monitor system and application logs for unusual command execution patterns or unexpected shell activity indicative of exploitation attempts. 4. Employ application-layer firewalls or intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics targeting command injection attempts. 5. If possible, run terminal-controller-mcp with the least privilege necessary to limit the impact of a successful exploit. 6. Engage with the software vendor or community to obtain patches or updates as soon as they become available and prioritize their deployment. 7. Conduct security awareness training for administrators to recognize and respond to signs of compromise related to this vulnerability. 8. Consider deploying endpoint detection and response (EDR) solutions to detect and contain exploitation attempts rapidly.
