CVE-2025-34514 is an authenticated OS command injection vulnerability identified in the firmware of Ilevia Srl.'s EVE X1 Server, specifically versions up to 4.7.18.0.eden. The vulnerability arises from improper neutralization of special elements in user-supplied input within multiple PHP scripts accessible via the web interface. These scripts invoke the PHP exec() function without adequate input validation or sanitization, enabling an attacker with valid credentials to inject and execute arbitrary OS commands on the underlying system. The attack vector requires authentication with low privileges, no user interaction, and can be exploited remotely over the network since the vulnerable service listens on port 8080. The vulnerability impacts confidentiality, integrity, and availability by allowing command execution that could lead to data theft, system compromise, or service disruption. Despite the severity, Ilevia has declined to issue a patch and instead advises customers to avoid exposing the management interface to the internet. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H) reflects the ease of exploitation and high impact. No public exploits have been reported yet, but the vulnerability's nature and access requirements make it a critical concern for organizations relying on this product for server management or control.

For European organizations, the impact of this vulnerability is significant. The EVE X1 Server is likely used in industrial, building automation, or critical infrastructure environments where Ilevia products have market presence. Successful exploitation could lead to unauthorized command execution, enabling attackers to exfiltrate sensitive data, disrupt operations, or pivot within internal networks. Given the authenticated nature of the vulnerability, insider threats or compromised credentials could facilitate attacks. The lack of a patch increases risk, as organizations must rely on network-level mitigations. Exposure of port 8080 to the internet or insufficient network segmentation could lead to remote exploitation. This could affect confidentiality by leaking sensitive operational data, integrity by altering system configurations or data, and availability by causing service outages. The potential for lateral movement within networks also raises concerns for broader organizational impact. European entities in sectors such as manufacturing, energy, or smart building management using EVE X1 Servers should consider this vulnerability a high priority.

Since Ilevia has declined to provide a patch, European organizations must implement compensating controls. First, immediately audit and restrict network exposure of the EVE X1 Server management interface, ensuring port 8080 is not accessible from untrusted networks or the internet. Employ strict firewall rules and network segmentation to isolate the device from general IT and internet-facing zones. Enforce strong authentication policies, including multi-factor authentication, to reduce the risk of credential compromise. Monitor logs for unusual authenticated command executions or access patterns. If feasible, replace or upgrade affected devices with alternative solutions that receive security updates. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection attempts or anomalous traffic targeting the server. Regularly review and update access control lists to limit user privileges to the minimum necessary. Finally, develop incident response plans specific to this vulnerability to quickly contain and remediate any exploitation attempts.
