CVE-2025-56092 is a critical OS command injection vulnerability found in the Ruijie X30 PRO V1 router firmware version X30-PRO-V1_09241521. The vulnerability resides in the /usr/local/lua/dev_sta/networkConnect.lua script, specifically in the module_get function, which processes POST requests. An attacker can craft a malicious POST request to this endpoint to inject and execute arbitrary operating system commands on the device. This type of vulnerability allows attackers to gain unauthorized control over the router, potentially leading to full system compromise. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. Although no CVSS score has been assigned yet, the nature of OS command injection vulnerabilities typically results in high severity due to the potential impact on confidentiality, integrity, and availability. The affected device is a network router commonly used in enterprise and possibly service provider environments, which could serve as a pivot point for further attacks within a network. No patches or mitigations have been officially published at the time of disclosure, and no known exploits are currently reported in the wild. However, the vulnerability's presence in a critical network device firmware highlights the urgency for affected organizations to assess their exposure and implement protective measures.

The exploitation of CVE-2025-56092 could have severe consequences for European organizations relying on Ruijie X30 PRO routers. Successful exploitation allows attackers to execute arbitrary commands, potentially leading to full device compromise. This can result in unauthorized access to internal networks, interception or manipulation of network traffic, disruption of network services, and the establishment of persistent backdoors. For enterprises, this could mean data breaches, operational downtime, and damage to reputation. Critical infrastructure and service providers using these devices may face risks to service availability and integrity. The vulnerability's ease of exploitation without authentication increases the likelihood of automated attacks and widespread impact. Given the interconnected nature of European networks and regulatory requirements such as GDPR, the breach of confidentiality and integrity could also lead to significant legal and financial repercussions.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include isolating vulnerable Ruijie X30 PRO devices from untrusted networks and restricting access to management interfaces via network segmentation and firewall rules. Deploy network intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious POST requests targeting the module_get endpoint. Conduct thorough inventory and vulnerability scanning to identify affected devices. Disable or restrict remote management features if not essential. Engage with Ruijie support channels to obtain firmware updates or security advisories as they become available. Additionally, implement strict input validation and filtering at the network perimeter to prevent injection payloads. Regularly monitor device logs for anomalous activity indicative of exploitation attempts. Finally, prepare incident response plans tailored to potential router compromise scenarios.
