CVE-2024-30078 is a high-severity vulnerability affecting Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability is classified under CWE-20, indicating improper input validation. Specifically, it resides in the Windows Wi-Fi driver, where insufficient validation of input data can be exploited remotely to execute arbitrary code. The CVSS v3.1 base score is 8.8, reflecting a high impact on confidentiality, integrity, and availability. The attack vector is adjacent network (AV:A), meaning an attacker must be within Wi-Fi range to exploit the vulnerability, but no privileges or user interaction are required (PR:N/UI:N). The vulnerability allows an unauthenticated attacker to send specially crafted Wi-Fi packets to a vulnerable system, triggering remote code execution (RCE). Successful exploitation could lead to full system compromise, including the ability to install programs, view, change, or delete data, or create new accounts with full user rights. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability was reserved in March 2024 and published in June 2024, indicating recent discovery and disclosure. Given the nature of the flaw in a core network driver, exploitation could be stealthy and impactful, especially in environments with many Wi-Fi enabled devices running the affected Windows 10 version.

For European organizations, this vulnerability poses a significant risk, especially those with large deployments of Windows 10 Version 1809 systems connected to Wi-Fi networks. The ability for an attacker to remotely execute code without authentication or user interaction means that attackers could potentially compromise critical systems silently. This could lead to data breaches, disruption of services, and lateral movement within corporate networks. Sectors such as finance, healthcare, government, and critical infrastructure, which often rely on Wi-Fi connectivity and have stringent data protection requirements under GDPR, are particularly vulnerable. The vulnerability could also be exploited in public or guest Wi-Fi environments common in European cities, airports, and enterprises, increasing the attack surface. The lack of known exploits in the wild suggests a window of opportunity for proactive mitigation before widespread exploitation occurs.

1. Immediate mitigation should focus on network-level controls: segment Wi-Fi networks from critical internal resources and implement strict network access controls and monitoring to detect anomalous Wi-Fi traffic. 2. Disable or restrict Wi-Fi interfaces on systems running Windows 10 Version 1809 where possible, especially on sensitive or high-value assets. 3. Deploy host-based intrusion detection/prevention systems (HIDS/HIPS) that can detect suspicious activity related to Wi-Fi driver exploitation. 4. Monitor network logs for unusual Wi-Fi management frames or malformed packets that could indicate exploitation attempts. 5. Apply any available Microsoft security updates promptly once released; if no patch is available, consider upgrading affected systems to a supported Windows version with active security updates. 6. Educate IT staff and security teams about the vulnerability to ensure rapid incident response capability. 7. Use network access control (NAC) solutions to enforce device compliance and restrict access from vulnerable endpoints. These measures go beyond generic advice by focusing on Wi-Fi network segmentation, monitoring, and host-level controls tailored to the nature of this vulnerability.
