CVE-2025-1710 is a high-severity vulnerability identified in the Endress+Hauser MEAC300-FNADE4 device, specifically within the maxView Storage Manager component. The core issue is an improper restriction of excessive authentication attempts (CWE-307), which means the system does not adequately limit the number of failed login attempts within a short timeframe. This deficiency makes the device susceptible to brute-force attacks, where an attacker can systematically try many password combinations without being locked out or delayed. The vulnerability has a CVSS v3.1 base score of 7.5, indicating a high level of risk. The attack vector is network-based (AV:N), requiring no privileges (PR:N) or user interaction (UI:N), and the scope is unchanged (S:U). The impact primarily affects confidentiality (C:H), with no direct impact on integrity or availability. Exploiting this vulnerability could allow an attacker to gain unauthorized access to the device or its management interface by guessing credentials, potentially exposing sensitive operational data or enabling further attacks within industrial control or monitoring environments. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in February 2025 and published in July 2025, indicating recent discovery and disclosure.

For European organizations, especially those operating in industrial automation, manufacturing, utilities, or critical infrastructure sectors, this vulnerability poses a significant risk. The Endress+Hauser MEAC300-FNADE4 is likely used in process automation and monitoring, where unauthorized access could lead to exposure of sensitive operational data or manipulation of system configurations. Although the vulnerability does not directly affect system integrity or availability, unauthorized access could be a stepping stone for attackers to conduct espionage, sabotage, or lateral movement within networks. Given the high reliance on industrial control systems in European energy, chemical, and manufacturing sectors, exploitation could disrupt operations or compromise safety. Additionally, regulatory frameworks such as NIS2 and GDPR in Europe emphasize the protection of critical infrastructure and personal data, so exploitation could lead to compliance violations and reputational damage. The lack of authentication barriers against brute-force attacks increases the risk of compromise, especially if weak or default credentials are in use.

To mitigate this vulnerability effectively, European organizations should implement the following specific measures: 1) Enforce strong password policies and immediately change any default or weak credentials on the affected devices. 2) Deploy network-level protections such as firewalls or access control lists to restrict management interface access to trusted IP addresses or network segments. 3) Implement intrusion detection or prevention systems (IDS/IPS) capable of detecting and blocking brute-force attempts targeting the MEAC300-FNADE4. 4) Monitor authentication logs closely for repeated failed login attempts and establish alerting mechanisms for suspicious activities. 5) Where possible, isolate the affected devices on dedicated management VLANs or networks to reduce exposure. 6) Engage with Endress+Hauser for updates or patches and apply them promptly once available. 7) Consider multi-factor authentication (MFA) if supported by the device or surrounding management infrastructure to add an additional layer of security. 8) Conduct regular security audits and penetration testing focusing on authentication mechanisms of industrial devices. These steps go beyond generic advice by focusing on network segmentation, monitoring, and proactive credential management tailored to industrial control environments.
