CVE-2025-34044 is a remote command injection vulnerability identified in the confirm.php interface of the WIFISKY 7-layer flow control router developed by Shenzhen Lingkong Technology. The vulnerability stems from improper neutralization of special elements in the 't' parameter of HTTP GET requests, classified under CWE-78. Due to insufficient input validation, unauthenticated attackers can craft malicious HTTP requests that inject arbitrary OS commands, which the router executes with elevated privileges. This can lead to full compromise of the device, allowing attackers to manipulate network traffic, exfiltrate sensitive data, disrupt services, or pivot into internal networks. The vulnerability has been assigned a CVSS 4.0 score of 9.4, reflecting its critical severity with network attack vector, low attack complexity, no authentication required, and no user interaction needed. Exploitation evidence was observed by the Shadowserver Foundation on January 25, 2025, indicating active reconnaissance or attack attempts in the wild, although no confirmed widespread exploitation is reported yet. The affected product is the WIFISKY 7-layer flow control router, with no specific version details beyond '0' provided, suggesting the vulnerability may affect all current versions. The lack of available patches at the time of publication increases the urgency for defensive measures. This vulnerability poses a significant threat to network security, especially in environments relying on these routers for traffic management and flow control.

For European organizations, exploitation of CVE-2025-34044 could have severe consequences. Compromise of WIFISKY routers may lead to unauthorized access to internal networks, interception or manipulation of sensitive communications, and disruption of critical network services. This is particularly concerning for sectors such as telecommunications, finance, government, and critical infrastructure where these routers might be deployed. Attackers could leverage this vulnerability to establish persistent footholds, conduct espionage, or launch further attacks within corporate or national networks. The ability to execute arbitrary OS commands remotely without authentication amplifies the risk of large-scale network outages or data breaches. Given the critical role of routers in network security and traffic management, the integrity and availability of network operations could be severely impacted. Additionally, the vulnerability could be exploited to bypass security controls, disable logging, or deploy malware, complicating incident detection and response efforts. The threat also raises concerns about supply chain security if these devices are widely used in managed service provider environments across Europe.

1. Immediate monitoring and filtering: Implement network-level intrusion detection and prevention systems (IDS/IPS) to detect and block suspicious HTTP GET requests targeting the confirm.php interface, especially those containing unusual or encoded characters in the 't' parameter. 2. Access control: Restrict access to router management interfaces to trusted IP addresses and networks, ideally isolating these devices from direct internet exposure. 3. Vendor engagement: Maintain close communication with Shenzhen Lingkong Technology for timely release and deployment of official security patches or firmware updates addressing this vulnerability. 4. Network segmentation: Segment critical network infrastructure to limit the potential lateral movement of attackers if a router is compromised. 5. Incident response readiness: Prepare and test incident response plans focusing on router compromise scenarios, including forensic analysis and rapid device replacement. 6. Configuration review: Audit router configurations for unnecessary services or interfaces that could be exploited and disable them where possible. 7. Logging and alerting: Enhance logging on network devices and correlate logs centrally to detect anomalous command execution or traffic patterns indicative of exploitation attempts. 8. Employee awareness: Train network administrators to recognize signs of compromise and suspicious network behavior related to router management interfaces. 9. Alternative controls: Consider deploying additional security layers such as web application firewalls (WAFs) to inspect and sanitize HTTP traffic directed at network devices. 10. Inventory and asset management: Maintain an up-to-date inventory of all Shenzhen Lingkong Technology devices to prioritize patching and monitoring efforts.
