CVE-2024-53941 is a vulnerability identified in the Victure RX1800 WiFi 6 Router, specifically in the software version EN_V1.0.0_r12_110933 and hardware version 1.0. The flaw allows a remote attacker, who is within the wireless range of the router, to derive the default Wi-Fi Pre-Shared Key (PSK) by leveraging information leaked through the last four octets of the router's BSSID (Basic Service Set Identifier). The BSSID is a MAC address that uniquely identifies the wireless access point. In this case, the design or implementation flaw ties the default PSK generation or assignment directly to the BSSID, enabling attackers to reverse-engineer or predict the Wi-Fi password without any authentication or user interaction. This vulnerability falls under CWE-863 (Incorrect Authorization), indicating a failure in properly restricting access to sensitive information. The CVSS v3.1 score of 8.8 reflects a high severity due to the ease of exploitation (attack vector is adjacent network), no privileges or user interaction required, and the potential for complete compromise of confidentiality, integrity, and availability of the Wi-Fi network and connected devices. Although no patches or official fixes have been published yet, the vulnerability poses a significant risk to any environment using the affected router model, especially where Wi-Fi security is critical. The lack of known exploits in the wild suggests it is a newly disclosed issue, but the simplicity of the attack vector means it could be weaponized quickly.

The impact of CVE-2024-53941 is substantial for organizations relying on the Victure RX1800 WiFi 6 Router. Successful exploitation allows an attacker to gain unauthorized access to the wireless network by deriving the default PSK, bypassing all Wi-Fi authentication mechanisms. This can lead to eavesdropping on network traffic, interception of sensitive data, lateral movement within the network, injection of malicious payloads, and disruption of network availability. Confidentiality is compromised as attackers can monitor or capture data transmitted over the network. Integrity is at risk if attackers manipulate network traffic or connected devices. Availability can be affected if attackers launch denial-of-service attacks or disrupt network operations. The vulnerability is particularly dangerous in environments with sensitive information, such as corporate offices, healthcare facilities, or government agencies, where Wi-Fi access controls are critical. Additionally, the ease of exploitation without user interaction or credentials increases the likelihood of attacks in public or semi-public spaces where the router is deployed.

To mitigate CVE-2024-53941, organizations should take immediate and specific actions beyond generic advice: 1) Replace the Victure RX1800 WiFi 6 Router with a model that does not exhibit this vulnerability or wait for an official firmware patch from the vendor before continued use. 2) If replacement is not immediately feasible, disable the default Wi-Fi network and configure a new, strong, and random PSK that is not derivable from the BSSID or any other device identifiers. 3) Restrict physical and wireless proximity to the router by deploying it in secure, controlled areas and using directional antennas or signal limiting techniques to reduce signal leakage outside trusted zones. 4) Monitor wireless networks for unauthorized connections or unusual activity that could indicate exploitation attempts. 5) Employ network segmentation and strong internal access controls to limit the impact of any compromised Wi-Fi access. 6) Educate users about the risks of connecting to unsecured or compromised Wi-Fi networks and encourage the use of VPNs for sensitive communications. 7) Stay updated with vendor advisories and apply patches promptly once available.
