CVE-2025-9424 is a security vulnerability identified in the Ruijie WS7204-A network device firmware version 2017.06.15. The vulnerability exists in an unspecified functionality within the file /itbox_pi/branch_import.php, specifically in the handling of the 'province' argument in the 'branch_list' parameter. Improper sanitization or validation of this input allows an attacker to perform OS command injection remotely. This means that an attacker can inject arbitrary operating system commands through the vulnerable parameter, potentially gaining unauthorized control over the affected device. The vulnerability can be exploited without user interaction and does not require prior authentication, increasing the risk of remote compromise. Although the vendor was notified early, no response or patch has been provided, and a public exploit is available, which raises the risk of exploitation. The CVSS v4.0 base score is 5.1 (medium severity), reflecting the network attack vector, low complexity, no privileges required, no user interaction, and limited impact on confidentiality, integrity, and availability. However, the presence of a public exploit and lack of vendor mitigation increases the urgency of addressing this issue. The Ruijie WS7204-A is a network device likely used in enterprise or organizational environments, making this vulnerability a significant concern for network security and operational continuity.

For European organizations, exploitation of this vulnerability could lead to unauthorized remote command execution on critical network infrastructure, potentially resulting in data breaches, network disruption, or lateral movement within internal networks. Given that the Ruijie WS7204-A is a network device, successful exploitation could compromise network traffic integrity and confidentiality, disrupt communications, or allow attackers to pivot to other systems. The lack of vendor response and patch availability increases the risk that attackers may leverage this vulnerability in targeted attacks or automated scanning campaigns. Organizations relying on these devices for branch connectivity or network management could face operational downtime or data exfiltration risks. Additionally, regulatory compliance requirements such as GDPR impose strict obligations on protecting personal data, and a breach stemming from this vulnerability could lead to legal and financial consequences for affected European entities.

Since no official patch or vendor response is available, European organizations should implement compensating controls immediately. These include isolating the affected devices from untrusted networks, restricting management interfaces to trusted IP addresses via firewall rules, and monitoring network traffic for suspicious activity related to the /itbox_pi/branch_import.php endpoint. Network segmentation should be enforced to limit the potential spread of compromise. Organizations should also consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to detect and block command injection attempts targeting the vulnerable parameter. Regularly auditing device configurations and logs for anomalies is critical. If possible, upgrading to a newer, unaffected firmware version or replacing the device with a secure alternative should be prioritized. Finally, organizations should maintain an incident response plan to quickly address any exploitation attempts.
