JPCERT (Japan Computer Emergency Response Team) has confirmed that there are active command injection attacks targeting Array AG Gateway devices. Command injection vulnerabilities allow attackers to execute arbitrary system commands on the affected device, which can lead to full system compromise. Array AG Gateways are network security appliances commonly used for secure remote access, SSL VPN, and traffic management. Although the exact vulnerable versions have not been disclosed, the presence of active exploitation attempts indicates that threat actors are leveraging this vulnerability to gain unauthorized access. The attacks are significant because command injection can bypass authentication or escalate privileges, enabling attackers to manipulate network traffic, exfiltrate sensitive data, or deploy further malware. Currently, there are no publicly known exploits or patches available, but the threat is rated high due to the critical nature of these devices in enterprise environments. The source of this information is a trusted cybersecurity news outlet, The Hacker News, and the confirmation comes from JPCERT, lending credibility to the report. The discussion on Reddit’s InfoSecNews subreddit is minimal, suggesting early-stage awareness. Organizations using Array AG Gateways should anticipate vendor advisories and prepare incident response plans. The lack of detailed technical indicators or CVEs limits immediate detection but does not reduce the urgency of the threat. This vulnerability impacts confidentiality, integrity, and availability, as attackers can execute arbitrary commands remotely without user interaction once the gateway is exposed. The attack surface includes any exposed management interfaces or improperly segmented network zones. Given the critical role of these gateways in secure communications, exploitation could disrupt business operations and compromise sensitive information.

For European organizations, the impact of this threat can be severe. Array AG Gateways are often deployed in enterprises and critical infrastructure sectors such as finance, healthcare, and government for secure remote access and traffic filtering. Successful exploitation could lead to unauthorized access to internal networks, data breaches, disruption of secure communications, and potential lateral movement within corporate environments. This can result in loss of sensitive customer or operational data, regulatory non-compliance (e.g., GDPR violations), and operational downtime. The integrity of network traffic could be compromised, enabling attackers to manipulate or intercept communications. Availability may also be affected if attackers deploy ransomware or disrupt gateway functionality. The lack of patches or detailed indicators increases the risk of undetected compromise. European organizations with remote workforce setups relying on these gateways are particularly vulnerable. The threat also raises concerns about supply chain security if these devices are widely used by managed service providers or critical infrastructure operators.

1. Immediately audit and restrict access to Array AG Gateway management interfaces, ensuring they are not exposed to untrusted networks or the internet. 2. Implement strict network segmentation to isolate gateway devices from general user networks and limit lateral movement opportunities. 3. Monitor network traffic and device logs for unusual command execution patterns or unauthorized access attempts, using advanced threat detection tools. 4. Apply any vendor-issued patches or firmware updates as soon as they become available; maintain close communication with Array Networks for advisories. 5. Employ multi-factor authentication (MFA) for administrative access to the gateways to reduce the risk of credential compromise. 6. Conduct vulnerability scans and penetration testing focused on these devices to identify potential weaknesses proactively. 7. Prepare incident response plans specific to gateway compromise scenarios, including containment and recovery procedures. 8. Educate IT and security teams about the nature of command injection attacks and signs of exploitation. 9. Consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block command injection attempts targeting these devices. 10. Review and update asset inventories to ensure all Array AG Gateways are accounted for and properly managed.
