CVE-2024-57235 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 'iface' parameter within the 'vif_enable' function. This flaw allows an unauthenticated remote attacker to inject arbitrary commands that the system executes with the privileges of the affected service. The vulnerability is classified under CWE-77, which pertains to improper neutralization of special elements used in a command ('Command Injection'). The CVSS v3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N) shows that the attack can be performed remotely over the network without any privileges or user interaction, impacting confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches or vendor advisories have been published yet. The vulnerability's exploitation could allow attackers to execute arbitrary commands on the router, potentially leading to unauthorized access to network traffic, manipulation of router configurations, or pivoting to other devices within the network.

For European organizations, this vulnerability poses a significant risk, especially for small and medium enterprises (SMEs) and home office environments that commonly deploy consumer-grade routers like the NETGEAR RAX5. Exploitation could lead to unauthorized disclosure of sensitive data traversing the network, manipulation of routing or firewall rules, and potential lateral movement within corporate or home networks. Given that the attack requires no authentication or user interaction, attackers could scan for vulnerable devices and compromise them en masse, leading to espionage, data leakage, or use of compromised routers as a foothold for further attacks. The confidentiality and integrity of network communications are at risk, which is critical for compliance with European data protection regulations such as GDPR. Additionally, compromised routers could be used in botnets or for launching distributed denial-of-service (DDoS) attacks, indirectly affecting organizational availability and reputation.

Organizations and users should immediately verify if their NETGEAR RAX5 routers are running firmware version 1.0.2.26 and avoid exposure of the router's management interfaces to untrusted networks, especially the internet. Network segmentation should be enforced to isolate IoT and consumer-grade devices from critical infrastructure. Employing network-level protections such as firewalls and intrusion detection/prevention systems (IDS/IPS) can help detect and block exploitation attempts. Monitoring router logs for unusual command executions or configuration changes is advisable. Since no official patches are currently available, users should subscribe to NETGEAR security advisories and apply firmware updates as soon as they are released. As a temporary measure, disabling remote management features and changing default credentials can reduce the attack surface. Organizations should also consider replacing vulnerable devices with enterprise-grade routers that have stronger security postures and vendor support.
