CVE-2024-41992 is a vulnerability in the Wi-Fi Alliance's wfa_dut component of the Wi-Fi Test Suite, present up to version 9.0.0. The flaw stems from the unsafe invocation of the system() library function to handle 802.11x frames, which enables OS command injection. Specifically, crafted 802.11x frames can be sent to devices running this software, leading to remote code execution with root privileges. The Arcadyan FMIMG51AX000J device is a confirmed affected product, where the vulnerability can be exploited remotely via TCP ports 8000 or 8080 on the LAN interface. Other devices using the same vulnerable component may be exploitable over WAN interfaces, increasing the attack surface. The vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), indicating a classic command injection issue. The CVSS v3.1 base score is 8.8, reflecting high impact and ease of exploitation without requiring privileges or user interaction. Although no public exploits have been reported, the root-level access granted by this flaw could allow attackers to fully compromise affected devices, manipulate network traffic, or pivot within internal networks. The vulnerability affects Wi-Fi testing environments and devices that incorporate the wfa_dut component, which is used for Wi-Fi certification and testing processes. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to prevent exploitation.

The impact of CVE-2024-41992 is severe for organizations relying on affected Wi-Fi testing tools and devices. Successful exploitation grants attackers root-level remote code execution, compromising confidentiality by allowing data theft or interception, integrity by enabling manipulation of device configurations or network traffic, and availability by potentially causing device crashes or denial of service. In environments where these devices are connected to critical infrastructure or internal networks, attackers could use compromised devices as footholds to escalate attacks or move laterally. The vulnerability's presence on LAN and potentially WAN interfaces broadens the attack vector, increasing risk from both internal and external threat actors. Enterprises using Arcadyan FMIMG51AX000J or similar devices may face operational disruptions, data breaches, and regulatory compliance issues. The lack of authentication and user interaction requirements further heightens the threat, enabling automated exploitation. The vulnerability also poses risks to Wi-Fi certification labs and manufacturers, potentially undermining trust in Wi-Fi testing processes.

To mitigate CVE-2024-41992, organizations should immediately restrict network access to the affected TCP ports (8000 and 8080) on LAN and WAN interfaces to trusted personnel and systems only. Network segmentation should isolate vulnerable devices from critical infrastructure and limit exposure to untrusted networks. Employ strict firewall rules and access control lists to block unauthorized traffic targeting the wfa_dut service. Monitor network traffic for unusual activity on the specified ports and implement intrusion detection/prevention systems with signatures tuned for command injection attempts. Where possible, disable or remove the Wi-Fi Test Suite or wfa_dut component from production environments if not actively used. Coordinate with device vendors and the Wi-Fi Alliance for patches or updates addressing this vulnerability and apply them promptly once available. Conduct thorough security assessments of devices incorporating this component to identify and remediate any signs of compromise. Additionally, implement robust logging and alerting to detect exploitation attempts early. For organizations operating Wi-Fi certification labs, enforce strict physical and network security controls to prevent unauthorized access.
