Schneider Electric’s Enerlin’X IFE and eIFE Solutions: A Comprehensive Analysis of Vulnerabilities and Mitigations
1. EXECUTIVE SUMMARY
Schneider Electric’s Enerlin’X IFE and eIFE solutions have recently been identified as having critical vulnerabilities that could be exploited remotely, posing significant risks to users. The vulnerabilities stem from improper input validation, which could lead to denial-of-service (DoS) conditions requiring manual intervention to reboot affected devices. With a CVSS v4 score of 7.1, these vulnerabilities demand immediate attention from organizations utilizing these systems, particularly in critical infrastructure sectors such as energy and manufacturing.
2. RISK EVALUATION
The successful exploitation of these vulnerabilities could result in a denial-of-service condition, disrupting operations and necessitating manual rebooting of the devices. This could have cascading effects on operational efficiency, particularly in environments where uptime is critical. Organizations must assess their exposure to these vulnerabilities and implement appropriate mitigations to safeguard their systems.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The vulnerabilities affect all versions of the following Schneider Electric products:
- Enerlin’X IFE interface: All versions
- Enerlin’X eIFE: All versions
3.2 VULNERABILITY OVERVIEW
Three specific vulnerabilities have been identified, all categorized under improper input validation (CWE-20). Each vulnerability allows for denial-of-service attacks through different types of malicious packets:
3.2.1 CVE-2025-0816
This vulnerability allows attackers to send malicious IPV6 packets to the device, potentially causing a denial-of-service condition. It has a CVSS v3.1 base score of 6.5 and a CVSS v4 score of 7.1.
3.2.2 CVE-2025-0815
Similar to CVE-2025-0816, this vulnerability involves malicious ICMPV6 packets that can lead to a denial-of-service condition. It shares the same CVSS scores as CVE-2025-0816.
3.2.3 CVE-2025-0814
This vulnerability allows for denial-of-service attacks on network services running on the product when malicious IEC61850-MMS packets are sent. The core functionality of the breaker remains intact during the attack, but the network services are compromised. It has a CVSS v3.1 base score of 5.3 and a CVSS v4 score of 6.9.
3.3 BACKGROUND
- CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing, Energy
- COUNTRIES/AREAS DEPLOYED: Worldwide
- COMPANY HEADQUARTERS LOCATION: France
3.4 RESEARCHER
Schneider Electric proactively reported these vulnerabilities to the Cybersecurity and Infrastructure Security Agency (CISA), demonstrating a commitment to transparency and user safety.
4. MITIGATIONS
To address these vulnerabilities, Schneider Electric has outlined specific remediations and mitigations:
- Firmware Update: Users should upgrade to version 004.010.000 of Enerlin’X IFE and eIFE, which includes fixes for the identified vulnerabilities. The latest firmware can be downloaded through the EcoStruxure Power Commission tool.
Organizations are advised to follow appropriate patching methodologies, including backing up systems and testing patches in a controlled environment before deployment. Schneider Electric’s Customer Care Center is available for assistance with patch removal if necessary.
If users opt not to apply the recommended firmware updates, they should implement the following mitigations:
- Protected Environment: Use devices only in a protected environment to minimize network exposure and ensure they are not accessible from public or untrusted networks.
- Network Segmentation: Set up network segmentation and implement firewalls to block unauthorized access to the product’s ports.
- Access Control List Configuration: Follow the recommendations in Schneider Electric’s Cybersecurity Guide to configure the Access Control List appropriately.
- Security Notifications: Subscribe to Schneider Electric’s security notification service to stay informed about updates and remediation plans.
Schneider Electric also recommends adhering to industry cybersecurity best practices:
- Network Isolation: Isolate control and safety system networks from business networks using firewalls.
- Physical Security: Implement physical controls to prevent unauthorized access to industrial control systems.
- Secure Programming Practices: Keep programming software isolated from other networks and scan all mobile data exchange methods before use.
- Remote Access Security: Use secure methods, such as VPNs, for remote access, while recognizing their potential vulnerabilities.
For further guidance, organizations can refer to Schneider Electric’s Recommended Cybersecurity Best Practices document.
