CVE-2024-45880 is a critical command injection vulnerability identified in Motorola CX2L routers running firmware version 1.0.2 and earlier. The vulnerability resides in the SetStationSettings function, which is responsible for configuring network parameters such as the MAC address. This function improperly invokes system-level commands via the system() call without adequate input sanitization or validation, allowing an attacker to inject arbitrary shell commands. The vulnerability requires low-level privileges (PR:L) but does not require user interaction (UI:N), and can be exploited remotely over the network (AV:A). Successful exploitation can lead to complete compromise of the router, enabling attackers to execute arbitrary commands with the privileges of the router’s operating system. This can result in unauthorized access, data interception, network disruption, or pivoting to other internal systems. The CVSS v3.1 score of 8.0 reflects high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction needed. Although no public exploits have been reported yet, the nature of the vulnerability and the widespread use of such routers in enterprise and ISP environments make it a significant threat. No official patches have been released at the time of publication, increasing the urgency for mitigation.

The impact of CVE-2024-45880 is substantial for organizations relying on Motorola CX2L routers. Exploitation can lead to full system compromise, allowing attackers to execute arbitrary commands, potentially leading to data theft, network disruption, or further lateral movement within internal networks. Confidentiality is at risk as attackers could intercept or manipulate network traffic. Integrity is compromised through unauthorized configuration changes or injection of malicious code. Availability may be affected if attackers disrupt router operations or launch denial-of-service conditions. Given that routers are critical network infrastructure components, their compromise can have cascading effects on organizational security posture and operational continuity. Enterprises, ISPs, and managed service providers using these devices face increased risk of targeted attacks or automated exploitation once public exploits emerge.

1. Immediately restrict access to the router’s management interface to trusted administrators only, preferably via VPN or secure management VLANs. 2. Monitor network traffic and router logs for unusual command execution patterns or unauthorized configuration changes. 3. Disable remote management interfaces if not required. 4. Apply any firmware updates or patches released by Motorola as soon as they become available. 5. If no patch is available, consider replacing affected routers with models not vulnerable to this issue. 6. Implement network segmentation to limit the impact of a compromised router. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection attempts targeting router management functions. 8. Educate network administrators about the vulnerability and ensure strong authentication mechanisms are in place to prevent unauthorized access.
