Detect Windows Wi-Fi Driver Remote Code Execution via Adjacent Network in Splunk

CVE-2024-30078 is a high-severity (CVSS 8.8) remote code execution vulnerability in the Windows Wi-Fi Driver. An unauthenticated attacker within Wi-Fi radio range of a target can execute arbitrary code on the victim's device by sending a specially crafted network packet. No user interaction is required. The attack vector is 'Adjacent Network' (AV:A), meaning the attacker must be on the same network segment or within Wi-Fi broadcast range. All supported Windows versions are affected (Windows 10, 11, Server 2008–2022). This vulnerability is particularly relevant for SMB environments where employees work in shared offices, co-working spaces, hotels, or coffee shops — any shared Wi-Fi environment with other devices in range becomes a potential attack surface. Despite no confirmed in-the-wild exploitation at time of disclosure, the lack of user interaction makes it a high-priority patch.
