CVE-2024-7397 is a command injection vulnerability classified under CWE-77, found in the Korenix JetPort 5601v3 device firmware versions through 1.2. The root cause is improper neutralization of special characters in user-supplied input, which allows an attacker to inject and execute arbitrary system commands remotely. The vulnerability is 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/PR:N/UI:N/VC:H/VI:H/VA:H) reflects that the attack can be launched remotely with low complexity and no privileges, and it results in high impact on confidentiality, integrity, and availability. Successful exploitation could allow attackers to take full control of the device, manipulate network traffic, disrupt communications, or use the compromised device as a foothold for further attacks within the network. Although no public exploits are currently reported, the nature of command injection vulnerabilities typically leads to rapid development of exploit code. The affected product, Korenix JetPort 5601v3, is an industrial network device often deployed in critical infrastructure environments, increasing the potential impact of exploitation. The lack of available patches at the time of disclosure necessitates immediate risk mitigation steps by affected organizations.

For European organizations, especially those in industrial, manufacturing, and critical infrastructure sectors, this vulnerability poses a significant threat. Compromise of JetPort 5601v3 devices could lead to unauthorized control over network communications, data exfiltration, or disruption of operational technology (OT) environments. This could result in operational downtime, safety hazards, and financial losses. Given the device’s role in network connectivity, attackers could pivot from compromised devices to other critical systems, amplifying the impact. The vulnerability’s ease of exploitation and lack of authentication requirements increase the risk of widespread attacks. Additionally, disruption in sectors such as energy, transportation, and manufacturing could have cascading effects on supply chains and public services across Europe. The absence of known exploits currently provides a window for proactive defense, but also means organizations must act swiftly before exploitation becomes widespread.

Organizations should immediately identify and isolate all Korenix JetPort 5601v3 devices within their networks to limit exposure. Network segmentation should be enforced to restrict access to these devices only to trusted management hosts. Implement strict input validation and filtering at network boundaries where possible to detect and block suspicious command injection attempts. Monitor device logs and network traffic for unusual command execution patterns or anomalies indicative of exploitation attempts. Engage with Korenix support channels to obtain firmware updates or patches as soon as they become available and apply them promptly. If patches are delayed, consider temporary compensating controls such as disabling unnecessary services or restricting management interfaces to trusted IP addresses. Conduct thorough security audits of industrial control systems incorporating these devices and update incident response plans to include scenarios involving command injection attacks. Finally, raise awareness among operational technology teams about this vulnerability and the importance of rapid remediation.
