CVE-2025-34519 identifies a cryptographic vulnerability in the Ilevia EVE X1 Server firmware versions up to 4.7.18.0.eden, where passwords are hashed using the MD5 algorithm without any per-password salt. MD5 is a deprecated cryptographic hash function known for its speed and vulnerabilities to collision and preimage attacks. The absence of salting further exacerbates the risk by allowing attackers to leverage precomputed rainbow tables and efficient brute-force or dictionary attacks against stolen password hashes. The vulnerability is exploitable remotely without authentication by accessing the service running on port 8080, which the vendor recommends not exposing to the internet. The CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low complexity, partial attack requirement, no privileges or user interaction, and high confidentiality impact. The vendor has declined to patch the vulnerability, leaving customers reliant on network-level mitigations. This vulnerability compromises the confidentiality of stored passwords, potentially enabling attackers to escalate privileges or move laterally within affected networks if password reuse or weak passwords are present. No public exploits have been reported yet, but the vulnerability's characteristics make it a significant risk if the password database is accessed through other means, such as secondary vulnerabilities or insider threats.

For European organizations, the primary impact is the potential compromise of user credentials stored on EVE X1 Servers. If attackers obtain the password database, they can recover plaintext passwords rapidly due to the weak MD5 hashing without salt. This can lead to unauthorized access to the server and connected systems, data breaches, and lateral movement within networks. Critical infrastructure or industrial control systems relying on EVE X1 Servers could face operational disruptions or espionage risks. The inability to patch the vulnerability increases exposure, especially if port 8080 is inadvertently exposed to external networks. Confidentiality is severely impacted, while integrity and availability risks depend on the attacker's subsequent actions after credential compromise. The threat is heightened in sectors with high-value targets such as energy, manufacturing, and government services prevalent in Europe.

Since no patch is available, European organizations should implement strict network segmentation to isolate EVE X1 Servers from untrusted networks and the internet. Firewall rules must block inbound traffic to port 8080 from external sources. Employ VPNs or secure tunnels for remote management to avoid direct exposure. Regularly audit and monitor access logs for suspicious activity. Enforce strong password policies and consider multi-factor authentication where possible to reduce the impact of credential compromise. Backup critical data and have incident response plans ready for potential breaches. Organizations should also evaluate alternative products or firmware versions that do not use insecure hashing. If password databases are accessible, consider offline password hash cracking assessments to identify weak passwords proactively. Engage with Ilevia for any future updates or advisories.
