CVE-2025-34044 is a critical remote command injection vulnerability affecting the Shenzhen Lingkong Technology WIFISKY 7-layer flow control router. The vulnerability exists in the confirm.php interface, specifically via the 't' parameter in an HTTP GET request. Due to insufficient input validation and improper neutralization of special elements (CWE-78), unauthenticated attackers can inject arbitrary operating system commands remotely. This vulnerability does not require any authentication or user interaction, making it highly exploitable over the network. The CVSS 4.0 score of 9.4 reflects its critical severity, with a vector indicating network attack vector (AV:N), low attack complexity (AC:L), no authentication required (AT:N), and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level, as arbitrary OS commands can lead to full system compromise, data theft, service disruption, or pivoting within the network. The affected product, WIFISKY 7-layer flow control router, is a specialized network device used for traffic management and flow control, likely deployed in enterprise or ISP environments. No patches or known exploits in the wild are currently reported, but the critical nature and ease of exploitation make it a significant threat. The vulnerability is also associated with CWE-20 (improper input validation), indicating a fundamental flaw in input sanitization. Given the router's role in network infrastructure, exploitation could allow attackers to manipulate network traffic, intercept or disrupt communications, or establish persistent footholds within affected networks.

For European organizations, this vulnerability poses a severe risk to network infrastructure security. Organizations relying on Shenzhen Lingkong Technology's WIFISKY routers for traffic flow control could face unauthorized remote control of these devices, leading to potential data breaches, network outages, or lateral movement by attackers. Critical sectors such as telecommunications providers, ISPs, government agencies, and enterprises with complex network management needs are particularly vulnerable. Exploitation could disrupt essential services, compromise sensitive data, and undermine trust in network reliability. The lack of authentication and user interaction requirements increases the likelihood of automated exploitation attempts, potentially leading to widespread attacks. Additionally, the ability to execute arbitrary OS commands could allow attackers to deploy malware, create backdoors, or manipulate routing policies, severely impacting operational continuity and data integrity.

1. Immediate network-level controls: Restrict access to the confirm.php interface by implementing firewall rules or access control lists (ACLs) to limit exposure to trusted management networks only. 2. Network segmentation: Isolate WIFISKY routers from general user networks and the internet to reduce attack surface. 3. Monitor and log HTTP requests targeting the confirm.php endpoint, especially those containing unusual or suspicious 't' parameter values, to detect potential exploitation attempts. 4. Employ Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block command injection patterns targeting this vulnerability. 5. Engage with Shenzhen Lingkong Technology for official patches or firmware updates; if unavailable, consider temporary mitigations such as disabling or restricting the vulnerable interface. 6. Conduct thorough security audits and penetration tests focusing on router management interfaces to identify similar vulnerabilities. 7. Educate network administrators on the risks of exposing management interfaces and enforce strict credential and access management policies. 8. Implement network anomaly detection to identify unusual command execution or traffic patterns indicative of compromise.
