CVE-2024-55544 is a command injection vulnerability classified under CWE-77 affecting the ORing IAP-420 industrial automation product, specifically version 2.01e and earlier. The vulnerability stems from missing input validation in the device’s web interface, which allows an authenticated user with low privileges to inject and execute arbitrary operating system commands. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). No authentication bypass is possible, but the attacker only needs low privileges (PR:L) and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level (VC:H, VI:H, VA:H), potentially allowing attackers to take full control of the device, manipulate industrial processes, or disrupt operations. The device is typically used in industrial and critical infrastructure environments, where such compromise could have severe operational consequences. No public exploits or patches are currently available, increasing the urgency for defensive measures. The vulnerability was published on December 10, 2024, and assigned a CVSS v4.0 score of 8.7, indicating a high-severity issue.

For European organizations, especially those in industrial automation, manufacturing, and critical infrastructure sectors, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized command execution on devices controlling critical processes, potentially causing operational disruptions, data breaches, or safety hazards. The high impact on confidentiality, integrity, and availability means attackers could manipulate device configurations, exfiltrate sensitive data, or cause denial of service. Given the device’s role in industrial environments, such compromises could cascade into broader operational technology (OT) network disruptions. The lack of public exploits currently provides a limited window for proactive defense, but the high severity and ease of exploitation mean attackers may develop exploits rapidly. European organizations relying on ORing IAP-420 devices must prioritize mitigation to prevent potential targeted attacks or ransomware campaigns leveraging this vulnerability.

1. Immediately inventory all ORing IAP-420 devices in your environment and identify those running version 2.01e or below. 2. Restrict network access to the device management interface using firewalls and network segmentation, limiting access to trusted administrators only. 3. Implement strong authentication and monitoring on management interfaces to detect unusual login attempts or command executions. 4. Monitor network traffic for anomalous commands or patterns indicative of exploitation attempts. 5. Engage with ORing or authorized vendors to obtain firmware updates or patches as soon as they become available. 6. Until patches are released, consider isolating vulnerable devices from critical networks or deploying virtual patching via intrusion prevention systems (IPS) that can detect and block command injection attempts. 7. Conduct regular security assessments and penetration tests focusing on industrial control systems to identify similar vulnerabilities. 8. Train staff on the risks of command injection and the importance of secure device management practices.
