CVE-2025-1960
Remediation/Mitigation Strategy for CVE-2025-1960
Vulnerability Description:
- Vulnerability: CWE-1188: Initialization of a Resource with an Insecure Default. This vulnerability stems from the use of insecure default credentials (username and password) that are not changed upon initial system setup. The default username is also not displayed correctly within the WebHMI interface.
- Affected Product: Schneider Electric SE product(s) (specific product not provided in the report).
- Reported Date: 2025-03-12
Severity:
- CVSS v3.x Score: 9.8 (Critical)
- CVSS v3.x Vector: Base Score of 9.8 suggests that the vulnerability is network exploitable with low attack complexity, no required privileges, no user interaction, and a high impact to confidentiality, integrity and availability. (A precise CVSS vector string is not provided.)
- Severity Level: Critical
Known Exploit:
- The provided information does not explicitly state a known exploit exists, but the very high CVSS score indicates the potential for easy exploitation. It is highly likely that an attacker could leverage the unchanged default credentials to gain unauthorized access and execute commands. The fact that the username is not displayed correctly could further complicate identification of the default credentials needed to exploit.
Remediation/Mitigation Strategy:
Given the Critical severity and potential for easy exploitation, immediate action is required.
1. Immediate Actions (within 24-48 hours):
- Identify Affected Systems: Immediately identify all systems within your environment that are running the affected Schneider Electric SE product(s). Consult Schneider Electric’s advisories and documentation for specific affected product versions.
- Change Default Credentials: The highest priority action is to immediately change the default username and password on all identified systems. Use strong, unique passwords adhering to industry best practices (minimum 12 characters, complex characters, etc.). If the username is not displayed, attempt to determine the username and associated password through documentation or by contacting Schneider Electric technical support.
- Network Segmentation: Isolate the affected systems from the broader network where feasible. Place the systems behind firewalls and limit network access to only authorized users and systems. Implement strict access control lists (ACLs).
- Monitor for Suspicious Activity: Increase monitoring and logging on affected systems for any signs of unauthorized access or malicious activity. Pay close attention to login attempts, process execution, and network traffic.
- Emergency Patching (if available): Check Schneider Electric’s website for any available patches or firmware updates that address CVE-2025-1960. If a patch is available, apply it immediately after thorough testing in a non-production environment.
2. Long-Term Actions (within 1-4 weeks):
- Enforce Strong Password Policies: Implement organization-wide policies that require strong, unique passwords and regular password changes for all users, including system accounts.
- Implement Multi-Factor Authentication (MFA): Where supported, enable MFA for all user accounts, especially those with administrative privileges.
- Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and remediate potential security weaknesses. Pay special attention to default credentials and insecure configurations.
- Security Awareness Training: Provide security awareness training to all users, emphasizing the importance of changing default passwords and reporting suspicious activity.
- Secure Configuration Management: Implement a secure configuration management process to ensure that all systems are configured according to security best practices.
- Stay Informed: Subscribe to security advisories from Schneider Electric and other relevant vendors to stay informed about new vulnerabilities and security updates.
- Review WebHMI configuration: Contact Schneider Electric to determine why the default username is not displayed correctly.
3. Verification:
- After implementing the above steps, verify that the default credentials have been changed and that the systems are no longer vulnerable.
- Conduct penetration testing to simulate real-world attacks and identify any remaining vulnerabilities.
Reporting:
- Document all remediation steps taken, including the dates and times of each action.
- Report the vulnerability and the remediation steps to Schneider Electric and any other relevant authorities.
Disclaimer: This remediation strategy is based on the limited information provided. A complete and accurate assessment of the vulnerability and its potential impact is necessary to develop a comprehensive remediation plan. Always consult with security experts and Schneider Electric’s documentation for specific guidance.
