CVE-2024-53940 is a critical command injection vulnerability identified in the Victure RX1800 WiFi 6 Router, specifically in software version EN_V1.0.0_r12_110933 and hardware version 1.0. The vulnerability resides in the /cgi-bin/luci/admin web interface endpoints, which handle parameters for the ping utility. Due to insufficient input validation and sanitization, attackers can craft malicious payloads that inject arbitrary shell commands. These commands execute with root-level privileges, granting full control over the device. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing the risk of widespread exploitation. The CVSS 3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability. Although no public exploits or patches are currently available, the vulnerability represents a significant risk to affected devices. The underlying weakness corresponds to CWE-78 (Improper Neutralization of Special Elements used in an OS Command). This flaw could allow attackers to manipulate network traffic, intercept data, deploy malware, or disrupt network services by compromising the router. Given the router's role as a network gateway, successful exploitation could facilitate lateral movement within internal networks and persistent access.

The impact of CVE-2024-53940 is severe for organizations using the Victure RX1800 WiFi 6 routers. Attackers gaining root access can fully control the device, enabling interception and manipulation of all network traffic passing through the router. This compromises the confidentiality of sensitive data and the integrity of communications. Attackers can also disrupt network availability by disabling or reconfiguring the router, causing denial of service. The router could be leveraged as a foothold for further attacks within corporate or home networks, including lateral movement to other critical systems. For enterprises, this could lead to data breaches, espionage, or ransomware deployment. For home users, it risks privacy violations and unauthorized use of network resources. The lack of authentication and user interaction requirements makes the attack vector highly accessible to remote adversaries. Without timely patches, the vulnerability poses a persistent threat, especially in environments relying heavily on WiFi 6 infrastructure for connectivity.

1. Immediately isolate affected Victure RX1800 routers from untrusted networks to limit exposure. 2. Disable remote management interfaces or restrict access to trusted IP addresses only. 3. Monitor network traffic for unusual activity or command injection attempts targeting /cgi-bin/luci/admin endpoints. 4. Implement network segmentation to contain potential compromises and prevent lateral movement. 5. Use firewall rules to block access to the vulnerable endpoints from external sources. 6. Regularly check for firmware updates or security advisories from Victure and apply patches promptly once available. 7. Consider replacing vulnerable devices with alternative routers from vendors with robust security track records if patches are delayed. 8. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection patterns. 9. Educate network administrators about this vulnerability and encourage proactive security posture. 10. Maintain backups of router configurations and critical network infrastructure to enable rapid recovery if compromised.
