CVE-2025-27255
Remediation/Mitigation Strategy for CVE-2025-27255: GE Vernova EnerVista UR Setup - Hardcoded Credentials
Vulnerability: Use of Hard-coded Credentials
Product: GE Vernova EnerVista UR Setup
CVE ID: CVE-2025-27255
Severity: High (CVSS v3.1 Score: 8.0)
Description:
The EnerVista UR Setup application contains a vulnerability related to the use of hard-coded credentials. Specifically, the local user database is encrypted using a hardcoded password. An attacker who analyzes the application code can retrieve this password and use it to decrypt the user database, leading to potential privilege escalation.
Impact:
Successful exploitation of this vulnerability allows an attacker to:
- Gain unauthorized access: By decrypting the user database, the attacker can obtain usernames and passwords of legitimate users, including those with administrative privileges.
- Escalate privileges: An attacker gaining access to an administrator account can perform actions with elevated privileges, such as modifying system configurations, installing malicious software, or accessing sensitive data.
- Compromise System Security: The compromise of EnerVista UR Setup can lead to control system disruptions and impact the operations of the connected devices and systems.
Known Exploits:
While the provided information doesn’t explicitly state a publicly available exploit, the description indicates that the hardcoded password can be retrieved by analyzing the application code. This implies that a technically proficient attacker can develop and utilize an exploit. The ease of access to the hardcoded password would likely lead to more readily available exploits emerging once the vulnerability details are more widely disseminated.
Remediation/Mitigation Steps:
The following steps should be taken to remediate or mitigate the vulnerability:
Apply Vendor Patch/Update (Priority 1):
- The primary and most effective solution is to immediately apply any patches or updates released by GE Vernova specifically addressing CVE-2025-27255.
- Monitor GE Vernova’s security advisories and support channels for the availability of a fix.
- Prioritize the application of the patch in a testing environment first to ensure compatibility and stability before deploying it to production systems.
- Verify the patch installation and ensure the vulnerability is no longer exploitable.
Workarounds (if patch unavailable or delayed):
Network Segmentation (Priority 2):
- Isolate the EnerVista UR Setup application and associated systems within a segmented network to restrict unauthorized access.
- Implement strict firewall rules to limit network traffic to and from the affected systems.
- Monitor network traffic for suspicious activity related to the EnerVista UR Setup application.
Access Control and User Permissions (Priority 3):
- Enforce the principle of least privilege, granting users only the minimum necessary permissions required to perform their tasks.
- Review and update user accounts and passwords regularly.
- Consider implementing multi-factor authentication (MFA) for enhanced security, if supported.
Monitor and Audit User Activity (Priority 4):
- Implement robust logging and monitoring to detect suspicious activities or unauthorized access attempts.
- Regularly review audit logs to identify potential security breaches or anomalies.
- Consider deploying intrusion detection and prevention systems (IDS/IPS) to monitor for and block malicious activity.
Code Obfuscation (Temporary Measure, Least Effective):
- While not a replacement for a patch, obfuscating the application code may temporarily hinder attackers from easily identifying and extracting the hardcoded password. However, this is not a long-term solution and should be considered a temporary measure until a proper patch is available.
Security Awareness Training:
- Educate users on the risks associated with hard-coded credentials and the importance of using strong, unique passwords.
- Train users to recognize and report suspicious activity, such as phishing attempts or unauthorized access requests.
Vulnerability Scanning and Penetration Testing:
- Conduct regular vulnerability scans and penetration testing to identify potential security weaknesses in the EnerVista UR Setup application and related systems.
- Remediate any identified vulnerabilities promptly to minimize the risk of exploitation.
Incident Response Plan:
- Develop and maintain an incident response plan to address potential security breaches resulting from the exploitation of this vulnerability.
- Ensure that the incident response plan includes procedures for containing the breach, eradicating the threat, recovering affected systems, and notifying relevant stakeholders.
Long-Term Considerations:
- Secure Development Practices: GE Vernova should implement secure development lifecycle (SDLC) practices to prevent the introduction of similar vulnerabilities in future releases of EnerVista UR Setup and other products. This includes static and dynamic code analysis, security testing, and adherence to secure coding standards.
- Credential Management: Implement robust credential management practices to avoid the use of hard-coded credentials. Use secure methods for storing and managing sensitive information, such as encryption, key management systems, or hardware security modules (HSMs).
- Regular Security Audits: Conduct regular security audits of EnerVista UR Setup and related systems to identify and address potential security weaknesses.
Disclaimer: This remediation/mitigation strategy is based on the information provided and represents general best practices. The specific steps required may vary depending on the environment, configuration, and individual circumstances. Consult with security experts and refer to GE Vernova’s official security advisories for the most accurate and up-to-date guidance.
