Overview of the Vulnerability
CISA’s advisory reveals a critical flaw in the Hitachi Energy Relion series products, including models under the Relion 670/650/SAM600-IO umbrella. This vulnerability—categorized under CVE-2021-35534—stems from improper handling of insufficient privileges. In essence, attackers with valid user credentials can bypass the product’s security controls, opening up avenues for unauthorized modifications or even disabling the device entirely.Key points from the advisory include:
- Remotely Exploitable: The vulnerability can be exploited remotely with low attack complexity, making it accessible for threat actors, even if they face some hurdles in gaining initial access.
- CVSS Scores: The advisory reveals a CVSS version 3 score of 7.2 and an even more worrisome CVSS v4 score of 8.6, underlining the severity.
- Technical Exploitation: The flaw resides in the database schema and leverages the ODBC protocol (operating on TCP 2102). Once an attacker gains access to any account or session ticket, they can manipulate the database table to escalate privileges.
- Worldwide Impact: With deployments across critical energy sectors globally and headquarters in Switzerland, the potential reach of this vulnerability is significant.
Affected Products and Versions
The advisory details a long list of affected versions. While it’s important to consult the official Hitachi Energy PSIRT security advisory for specifics, here’s a summary of the affected product lines:- Relion 670/650 series: Several revisions from version 2.2.0 through lower revisions in subsequent updates.
- Relion 670/650/SAM600-IO series: Versions up to, but not including, secure revisions like 2.2.1.8.
- Legacy versions in the Relion 650 and 670 series that have not been updated to the most secure revisions are also at risk.
Mitigation Strategies
Hitachi Energy is not leaving its users in the lurch. The advisory includes a detailed update plan for each product version:- Immediate Software Updates: Users of affected systems are strongly advised to update to the latest secure revisions—such as updating to version 2.2.1.8 for certain lines.
- Network Segmentation: It is prudent to isolate industrial control systems (ICS) from the broader network. Ensure that ODBC protocol usage (TCP 2102) is confined within the substation or a secured internal network.
- Firewall Configurations: Implement strict firewall policies to reduce the attack surface. Only essential ports should be exposed, and remote access should be tightly controlled.
- Physical Security: Protect ICS assets physically from unauthorized access, preventing malicious insiders or external attackers from gaining direct access.
- Routine Risk Assessments: As CISA recommends, conduct regular impact analyses and risk assessments before deploying new updates or defensive measures.
Relevance to Windows Users
While Hitachi Energy’s products focus on ICS environments, many Windows-based networks have converged with operational technology (OT) systems in modern enterprises. IT teams managing Windows servers and critical infrastructure should:- Integrate Patch Management: Include relevant ICS updates in your organization’s patch management schedule. This ensures that all connected systems, even those traditionally managed outside the Windows ecosystem, remain secure.
- Monitor Network Traffic: Utilize Windows Defender or third-party intrusion detection systems (IDS) to monitor for unusual activity on ports commonly used for industrial protocols.
- Collaborate Across Departments: Engage with facility and OT network teams to craft a unified cybersecurity strategy that doesn’t overlook the increasing crossover between IT and OT systems.
FBI Alert: Data Extortion Scam Targeting Corporate Executives
Scam Overview
In a separate advisory, the FBI’s Internet Crime Complaint Center (IC3) has issued an alert about a data extortion scam targeting corporate executives. The perpetrators are operating under the guise of the “BianLian Group,” sending out extortion letters that threaten to expose sensitive information unless payments are made.The scam is particularly cunning:
- Masquerading Tactics: Cyber criminals impersonate an ostensibly organized group, thereby tricking even cautious executives into compliance.
- Extortion Demands: The letters contain threats to release sensitive data that could jeopardize personal and corporate reputations.
- Targeted Approach: By focusing on corporate executives, the scammers aim for high-value victims, banking on the assumption that high-profile individuals may be more susceptible to rapid extortion.
Mitigation and Reporting Guidance
For those who receive such suspicious communications—whether you're managing a Windows-based corporate network or an enterprise email system—the FBI and CISA recommend several defensive tactics:- Do Not Engage: Do not respond to threatening emails or follow the instructions. Engaging with extortionists can lead to further demands.
- Report Immediately: Organizations should contact CISA’s 24/7 Operations Center at Report@cisa.gov (via the designated phone line) and follow internal incident response protocols.
- Verify Communications: Always verify the legitimacy of unexpected communications. Use secondary channels to authenticate the source before taking any action.
- Educate Executives: Provide regular security briefings for corporate executives to help them recognize phishing tactics and extortion attempts.
Relevance to Corporate IT and Windows Administrators
For IT professionals managing corporate enterprises based on Windows infrastructure, this alert is a stern reminder of the importance of robust cybersecurity protocols:- Email Security: Strengthen email security by using advanced threat protection and filtering mechanisms to detect and quarantine scam or phishing emails.
- User Training: Conduct regular training sessions for executives and employees about identifying and handling suspicious communications.
- Incident Response Plans: Review and update your corporate incident response plans to ensure swift action in the event of a suspected extortion attempt.
- Data Backup and Encryption: Ensure critical data is backed up securely and encrypted. This limits the potential leverage an attacker may have if sensitive data is compromised.
Broader Cybersecurity Implications and Recommendations
Lessons for Windows Users and IT Professionals
Both advisories, though targeting different sectors, illustrate the evolving and interconnected nature of cyber threats today. Whether you manage Windows servers in a corporate environment or oversee ICS devices in an industrial setup, the ongoing cybersecurity challenges share common threads:- Patch and Update Rigorously: Cyber attackers exploit vulnerabilities that remain unpatched.
