The CVE-2025-34519 vulnerability affects the Ilevia EVE X1 Server firmware versions up to 4.7.18.0.eden by employing the MD5 hashing algorithm without a per-password salt to store user passwords. MD5 is a cryptographically broken and fast hash function, which makes it unsuitable for password hashing because it allows attackers to perform rapid offline attacks once the password hashes are obtained. The absence of salting further exacerbates this weakness by enabling the use of precomputed rainbow tables and simplifying brute-force attacks. An attacker who gains access to the password database—potentially via network exposure on port 8080 or other means—can recover user passwords efficiently, leading to credential compromise and potential unauthorized access to the system. The vendor, Ilevia Srl., has declined to patch this vulnerability and recommends customers avoid exposing the management interface externally. The CVSS 4.0 vector indicates the attack can be performed remotely over the network without privileges or user interaction, with high impact on confidentiality but no direct impact on integrity or availability. No known exploits are currently reported in the wild, but the vulnerability's nature makes it a critical risk if the password database is leaked or accessed.

For European organizations using the Ilevia EVE X1 Server, this vulnerability poses a significant threat to the confidentiality of user credentials. If attackers gain access to the password database, they can quickly recover plaintext passwords, potentially leading to unauthorized access to the server and lateral movement within the network. This can result in data breaches, disruption of services, and compromise of sensitive information. The lack of vendor remediation increases the risk exposure, especially for organizations that have the server management interface accessible over the internet or poorly segmented internal networks. Given the high CVSS score and ease of exploitation, the vulnerability could be leveraged in targeted attacks against critical infrastructure or enterprise environments in Europe, particularly in sectors relying on this product for server management. The impact extends beyond the immediate system, as compromised credentials may be reused or escalated, amplifying the damage.

Since Ilevia has declined to patch the vulnerability, European organizations must implement compensating controls. First, immediately restrict access to port 8080 by implementing strict firewall rules and network segmentation to ensure the EVE X1 Server management interface is not exposed to the internet or untrusted networks. Employ VPNs or zero-trust network access solutions for administrative access. Conduct thorough audits to identify any unauthorized access or password database leaks. Where possible, replace or upgrade the EVE X1 Server to a more secure product or firmware version if available. Implement strong password policies and consider multi-factor authentication (MFA) on systems integrated with the EVE X1 Server to reduce the impact of credential compromise. Regularly monitor logs for suspicious activity and prepare incident response plans for potential credential breaches. Finally, educate users about the risks of password reuse and encourage password changes if compromise is suspected.
