CVE-2024-55547 is a critical command injection vulnerability identified in the ORing IAP-420 device, specifically within its SNMP objects implemented using the NET-SNMP library. The vulnerability stems from CWE-77, which involves improper neutralization of special elements used in command execution contexts. In this case, the SNMP interface fails to properly sanitize input, allowing an unauthenticated remote attacker to inject and execute arbitrary system commands on the device. The affected product version is up to 2.01e, with no patches currently available. The vulnerability is remotely exploitable over the network without any authentication or user interaction, making it highly accessible to attackers. The CVSS 4.0 vector (AV:N/AC:L/AT:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) reflects that the attack can be performed remotely with low complexity, no privileges, and no user interaction, resulting in high confidentiality, integrity, and availability impacts. Successful exploitation could allow attackers to take full control of the device, disrupt industrial operations, manipulate data, or use the compromised device as a foothold for lateral movement within critical infrastructure networks. Although no known exploits have been reported in the wild, the severity and ease of exploitation make this a significant threat. The ORing IAP-420 is commonly deployed in industrial automation and critical infrastructure environments, which increases the potential impact of this vulnerability.

For European organizations, especially those operating in industrial automation, manufacturing, energy, transportation, and critical infrastructure sectors, this vulnerability poses a severe risk. Exploitation could lead to unauthorized command execution, resulting in operational disruption, data manipulation, or complete device takeover. This could cause downtime, safety hazards, and potential cascading failures in interconnected industrial systems. The confidentiality of sensitive operational data could be compromised, and integrity of control commands could be violated, leading to unsafe or unintended device behavior. Availability impacts could disrupt essential services, causing economic and reputational damage. Given the critical nature of industrial control systems in Europe’s energy grids, manufacturing plants, and transportation networks, the threat could have widespread consequences. The lack of authentication and user interaction requirements lowers the barrier for attackers, increasing the likelihood of exploitation if devices are exposed or insufficiently protected.

1. Immediately isolate ORing IAP-420 devices from untrusted networks by implementing strict network segmentation and firewall rules to restrict SNMP access only to trusted management stations. 2. Disable SNMP services on the device if not required, or restrict SNMP community strings and access control lists (ACLs) to minimize exposure. 3. Monitor SNMP traffic for unusual or malformed requests indicative of exploitation attempts using intrusion detection/prevention systems (IDS/IPS) tailored for industrial protocols. 4. Implement strict network monitoring and logging to detect anomalous command execution or unexpected device behavior. 5. Engage with ORing support and vendors for firmware updates or patches as they become available, and plan for timely deployment. 6. Conduct thorough asset inventories to identify all affected devices and prioritize remediation efforts. 7. Employ compensating controls such as multi-factor authentication for network access and enhanced physical security to reduce attack surface. 8. Train operational technology (OT) security teams on this vulnerability and response procedures to ensure rapid detection and containment.
