CVE-2025-46271 is an OS command injection vulnerability identified in Planet Technology's UNI-NMS-Lite, a network management system product. The vulnerability is classified under CWE-78, which pertains to improper neutralization of special elements used in OS commands. This flaw allows an unauthenticated attacker to inject arbitrary operating system commands through the vulnerable interface of UNI-NMS-Lite. Because the attacker does not require authentication, the attack surface is significantly broad. Successful exploitation could enable the attacker to read sensitive device data or manipulate device configurations and operations by executing arbitrary commands on the underlying operating system hosting the UNI-NMS-Lite software. The vulnerability affects version 0 of the product, which likely indicates an initial or early release version. No patches or mitigations have been published yet, and there are no known exploits in the wild as of the publication date (April 24, 2025). The vulnerability was reserved and enriched by ICS-CERT, indicating its relevance to industrial control systems or critical infrastructure environments. The lack of authentication requirement and the ability to execute OS commands directly pose a significant risk to the confidentiality, integrity, and availability of managed devices and networks controlled via UNI-NMS-Lite.

For European organizations, the impact of this vulnerability can be substantial, especially for those relying on Planet Technology's UNI-NMS-Lite for network management in critical infrastructure sectors such as telecommunications, manufacturing, utilities, and transportation. Exploitation could lead to unauthorized disclosure of sensitive network device data, unauthorized changes to device configurations, or disruption of network management operations. This could result in operational downtime, data breaches, and potential cascading effects on dependent services. Given the unauthenticated nature of the attack, threat actors could exploit this vulnerability remotely without prior access, increasing the risk of widespread compromise. The vulnerability could also be leveraged as a foothold for lateral movement within enterprise or industrial networks, potentially affecting multiple systems. The absence of known exploits currently provides a window for proactive mitigation, but the medium severity rating suggests that while the vulnerability is serious, it may require specific conditions or expertise to exploit effectively.

1. Immediate network segmentation: Isolate devices running UNI-NMS-Lite from untrusted networks and restrict access to management interfaces to trusted administrative networks only. 2. Implement strict input validation and sanitization at the application level if possible, or apply web application firewalls (WAFs) with custom rules to detect and block command injection patterns targeting UNI-NMS-Lite interfaces. 3. Monitor network traffic and logs for unusual command execution attempts or anomalous behavior related to UNI-NMS-Lite devices. 4. Limit the privileges of the UNI-NMS-Lite service account on the host OS to the minimum necessary, reducing the impact of potential command execution. 5. Engage with Planet Technology for updates or patches and apply them promptly once available. 6. Conduct regular vulnerability assessments and penetration testing focusing on network management systems to detect similar injection flaws. 7. Employ multi-factor authentication and VPN access for management interfaces to add layers of security, even though the vulnerability itself does not require authentication. 8. Prepare incident response plans specific to network management system compromises to enable rapid containment and recovery.
