CVE-2024-57234 is a command injection vulnerability identified in the NETGEAR RAX5 (AX1600 WiFi Router) firmware version 1.0.2.26. The vulnerability arises from improper input validation of the 'ifname' parameter within the 'apcli_cancel_wps' function. This flaw allows an unauthenticated remote attacker to inject arbitrary commands that the system executes with the privileges of the vulnerable service. The vulnerability is classified under CWE-77, which pertains to improper neutralization of special elements used in OS command injections. The CVSS v3.1 base score is 6.5, indicating a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects confidentiality and integrity but not availability, as indicated by the CVSS vector. No known exploits are currently reported in the wild, and no patches have been linked or published yet. The vulnerability could be exploited remotely over the network without authentication, making it a significant risk for exposed devices. The lack of authentication and user interaction requirements increases the attack surface, especially for devices accessible from untrusted networks. The vulnerability specifically targets the NETGEAR RAX5 router, a consumer-grade device commonly used in home and small office environments, which may be deployed in various European countries. Given the nature of command injection, successful exploitation could allow attackers to execute arbitrary commands, potentially leading to unauthorized access, data leakage, or further network compromise.

For European organizations, especially small businesses and home offices relying on NETGEAR RAX5 routers, this vulnerability poses a risk of unauthorized remote command execution. Attackers could leverage this flaw to gain control over the router, intercept or manipulate network traffic, and pivot to internal networks, compromising sensitive data and systems. The confidentiality and integrity of communications passing through the affected routers could be undermined. Although the vulnerability does not directly impact availability, the potential for lateral movement and data exfiltration could have severe operational and reputational consequences. Organizations with remote or hybrid work setups that use these routers without adequate network segmentation or monitoring are particularly vulnerable. Additionally, the absence of patches increases the window of exposure, and the medium severity score suggests that while exploitation is feasible, it may require some technical skill or specific conditions. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once details become public.

1. Immediate mitigation should include isolating NETGEAR RAX5 routers from direct exposure to untrusted networks, such as the internet, by placing them behind firewalls or VPNs. 2. Network administrators should monitor router logs and network traffic for unusual activity indicative of exploitation attempts targeting the 'apcli_cancel_wps' function or suspicious command execution patterns. 3. Disable WPS functionality if not required, as the vulnerability is linked to the WPS-related function, reducing the attack surface. 4. Implement strict network segmentation to limit the impact of a compromised router on critical internal systems. 5. Regularly check for firmware updates or security advisories from NETGEAR and apply patches promptly once available. 6. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics capable of detecting command injection attempts against routers. 7. Educate users and IT staff about the risks of using default or outdated router firmware and the importance of securing network devices. 8. Consider replacing vulnerable devices with models that have a strong security track record and timely patch support if patches are delayed.
