CVE-2025-9174 is a security vulnerability identified in the neurobin shc utility, specifically affecting versions 4.0.0 through 4.0.3. The flaw exists in the 'make' function within the src/shc.c source file, which is part of the Filename Handler component. This vulnerability allows for OS command injection, meaning an attacker with local access can manipulate inputs to execute arbitrary operating system commands. The injection occurs due to insufficient sanitization or validation of inputs handled by the 'make' function, enabling crafted input to be interpreted as OS commands. Exploitation requires local access with at least low-level privileges (PR:L), no user interaction is needed, and the attack complexity is low (AC:L). The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as the attacker can execute commands locally but cannot escalate privileges or remotely trigger the flaw. The CVSS v4.0 base score is 4.8 (medium severity), reflecting these factors. Although the exploit has been publicly disclosed, there are no known exploits in the wild currently. No patches or fixes have been linked yet, so mitigation relies on limiting local access and monitoring. This vulnerability is significant for environments where neurobin shc is used, particularly in development or build systems that rely on this tool for shell script compilation or obfuscation. Attackers with local access could leverage this flaw to execute malicious commands, potentially leading to unauthorized actions or disruption of services.

For European organizations, the impact of CVE-2025-9174 depends largely on the deployment of neurobin shc within their infrastructure. Organizations using this tool in development, build automation, or deployment pipelines may face risks of local command execution by unauthorized users or insiders. This could lead to unauthorized modification of build artifacts, insertion of malicious code, or disruption of build processes, impacting software integrity and availability. While remote exploitation is not possible, insider threats or compromised accounts with local access could exploit this vulnerability. In sectors with strict compliance requirements such as finance, healthcare, or critical infrastructure, even local command injection vulnerabilities can have serious implications for data integrity and operational continuity. Additionally, the lack of a patch increases the window of exposure. European organizations with shared development environments or CI/CD systems using neurobin shc should be particularly vigilant. The medium severity rating suggests that while the risk is not critical, it should not be ignored, especially in environments where local access control is weak or where the tool is widely used.

1. Restrict local access: Limit user permissions and access to systems running neurobin shc to trusted personnel only. Implement strict access controls and monitoring on build servers and developer workstations. 2. Input validation: Although patch details are unavailable, developers and administrators should review and sanitize inputs to the 'make' function or any interfaces invoking neurobin shc to prevent injection vectors. 3. Use containerization or sandboxing: Run neurobin shc within isolated environments to contain potential command injection impacts. 4. Monitor and audit: Implement logging and real-time monitoring of command executions and system calls on hosts running neurobin shc to detect suspicious activities. 5. Update policy: Track vendor advisories for patches or updates addressing this vulnerability and apply them promptly once available. 6. Alternative tools: Consider using alternative, more secure shell script compilers or obfuscators if feasible until a fix is released. 7. Educate developers and administrators about the risks of local command injection and enforce secure coding and operational practices around build tools.
