CVE-2025-34514 is an authenticated OS command injection vulnerability in the Ilevia EVE X1 Server firmware (versions ≤ 4.7.18.0.eden). The issue arises from multiple PHP scripts accessible via the web interface that invoke the exec() function without properly sanitizing user-supplied input. This improper neutralization of special elements (CWE-78) allows an attacker with valid credentials to inject arbitrary OS commands, potentially leading to full system compromise. The vulnerability requires authentication but no user interaction beyond that, and the attack vector is network-based over port 8080. The vendor, Ilevia Srl., has declined to issue patches and recommends customers avoid exposing the vulnerable service to the internet. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) reflects a network attack vector with low complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Although no exploits have been publicly observed, the vulnerability's nature and ease of exploitation make it a significant threat to affected deployments.

For European organizations using Ilevia EVE X1 Servers, this vulnerability poses a critical risk of unauthorized command execution, potentially leading to data breaches, service disruption, or lateral movement within networks. Given the high CVSS score and the ability to execute arbitrary commands, attackers could exfiltrate sensitive information, deploy ransomware, or establish persistent footholds. The lack of vendor patches increases exposure, especially for organizations that have not isolated the device from external networks. Critical infrastructure or industrial environments relying on these servers could face operational outages or safety risks. The impact extends to confidentiality, integrity, and availability, threatening compliance with European data protection regulations such as GDPR if personal data is compromised.

Since no patches are available, European organizations must implement compensating controls. First, immediately restrict network access to the EVE X1 Server by blocking port 8080 at the perimeter firewall and internal segmentation firewalls, allowing access only from trusted management networks. Disable or remove any unnecessary web services on the device. Enforce strong authentication and monitor authentication logs for suspicious activity. Employ intrusion detection/prevention systems (IDS/IPS) to detect anomalous command injection patterns. Consider deploying application-layer firewalls or web application firewalls (WAFs) to filter malicious payloads targeting the PHP scripts. If possible, replace or upgrade the device to a non-vulnerable alternative. Conduct regular vulnerability assessments and penetration tests focusing on these devices. Maintain strict asset inventories to identify all impacted systems.
