CVE-2025-34517 is an absolute path traversal vulnerability classified under CWE-22 affecting the Ilevia Srl. EVE X1 Server firmware versions up to 4.7.18.0.eden. The vulnerability resides in the get_file_content.php script, which fails to properly restrict file path inputs, allowing attackers to specify arbitrary absolute paths. This flaw enables remote, unauthenticated attackers to read any file accessible by the server process, potentially exposing sensitive configuration files, credentials, or other critical data. The vulnerability is exploitable over the network without any authentication or user interaction, targeting the server's port 8080. Despite the severity, Ilevia has declined to issue a patch and instead recommends that customers avoid exposing port 8080 to the internet. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, and high confidentiality impact with no impact on integrity or availability. No known exploits have been reported in the wild yet, but the vulnerability's nature and ease of exploitation make it a significant risk. The lack of a patch necessitates reliance on compensating controls such as network segmentation and access restrictions.

For European organizations, this vulnerability poses a critical risk to confidentiality, as attackers can remotely access arbitrary files without authentication. Exposure of sensitive data such as credentials, internal configurations, or personal data could lead to further compromise or regulatory violations under GDPR. Organizations with internet-facing EVE X1 Servers are particularly vulnerable to automated scanning and exploitation attempts. The inability to patch the vulnerability increases the risk profile, forcing reliance on network defenses. Critical infrastructure sectors or enterprises using these devices for operational technology or management functions may face operational disruptions if attackers leverage the information gained for subsequent attacks. The breach of confidentiality could also damage organizational reputation and lead to financial penalties. Given the high CVSS score and ease of exploitation, the threat is significant for any European entity deploying this product without adequate network protections.

Since no patch is available, European organizations should immediately implement strict network-level controls. This includes firewall rules to block all inbound traffic to port 8080 from untrusted networks, especially the internet. Deploy network segmentation to isolate EVE X1 Servers within secure internal zones inaccessible from external networks. Employ VPNs or zero-trust access models for remote management to avoid direct exposure. Monitor network traffic for unusual access attempts targeting port 8080 or the get_file_content.php endpoint. Conduct regular audits of exposed services and ensure that vulnerable devices are not inadvertently reachable externally. Consider deploying web application firewalls (WAF) with custom rules to detect and block path traversal attempts. Finally, maintain an inventory of all EVE X1 Server deployments to assess exposure and prioritize mitigation efforts. Organizations should also engage with Ilevia for any future updates or advisories.
