CVE-2025-14276 is a remote command injection vulnerability found in the Ilevia EVE X1 Server software, versions up to 4.6.5.0.eden. The flaw resides in an unspecified function within the /ajax/php/leaf_search.php file, where improper sanitization of input parameters allows an attacker to inject and execute arbitrary system commands. This vulnerability can be triggered remotely without authentication or user interaction, increasing its risk profile. However, the attack complexity is high, requiring detailed knowledge of the system and crafted input to succeed. The vendor has confirmed the vulnerability and indicated that many devices have already been patched. They also recommend closing the server’s external ports to prevent unauthorized access. The CVSS 4.0 base score of 6.3 reflects a medium severity, with network attack vector, high attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is low to limited, as the vulnerability affects a specific function and does not appear to allow full system compromise easily. No public exploits are known at this time, but the vulnerability has been publicly disclosed, which may increase the risk of future exploitation. Organizations running affected versions should prioritize upgrading to patched versions and restrict network access to the vulnerable service to mitigate potential attacks.

For European organizations using the Ilevia EVE X1 Server, this vulnerability poses a moderate risk. Successful exploitation could allow attackers to execute arbitrary commands on the server, potentially leading to unauthorized data access, service disruption, or lateral movement within the network. Although the exploit complexity is high and no known active exploits exist, the public disclosure increases the likelihood of future attacks. The impact on confidentiality, integrity, and availability is limited but could escalate if combined with other vulnerabilities or misconfigurations. Organizations in critical infrastructure sectors or those relying heavily on Ilevia EVE X1 Server for operational technology or network management could face operational disruptions or data breaches. The recommendation to close external ports is particularly relevant to prevent remote exploitation, as exposure to the internet significantly increases risk. Failure to apply patches or network restrictions could leave systems vulnerable to targeted attacks, especially from sophisticated threat actors.

1. Immediately upgrade all Ilevia EVE X1 Server instances to the latest patched version beyond 4.6.5.0.eden where the vulnerability is resolved. 2. Restrict network access to the affected server by closing or firewalling external ports that expose the /ajax/php/leaf_search.php endpoint, limiting access to trusted internal networks only. 3. Implement network segmentation to isolate the EVE X1 Server from critical infrastructure and sensitive data environments. 4. Monitor server logs and network traffic for unusual command execution attempts or anomalous activity targeting the vulnerable endpoint. 5. Conduct regular vulnerability scans and penetration tests focusing on command injection vectors to identify residual risks. 6. Educate system administrators on the importance of timely patching and network exposure minimization for critical management servers. 7. Employ application-layer firewalls or web application firewalls (WAFs) with custom rules to detect and block injection attempts against the vulnerable PHP script. 8. Maintain an incident response plan that includes procedures for command injection attacks to enable rapid containment and remediation.
