CVE-2024-32394 is a remote code execution (RCE) vulnerability identified in Ruijie RG-RSR10-01G-T(WA)-S network devices running the RSR_3.0(1)B9P2 firmware version. The flaw allows an unauthenticated remote attacker to execute arbitrary code by sending a specially crafted HTTP request to the device's management interface. This vulnerability does not require any prior authentication or user interaction, making it highly exploitable in exposed network environments. The vulnerability affects the device's HTTP service, which likely processes incoming requests without sufficient input validation or proper memory handling, leading to code execution. The CVSS v3.1 score of 8.8 reflects the high impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. Although no public exploits or active exploitation have been reported yet, the nature of the vulnerability and the critical role of these devices in network infrastructure make it a significant threat. Ruijie devices are widely deployed in enterprise, government, and service provider networks, where compromise could lead to network disruption, data interception, or lateral movement within internal networks. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through network segmentation, access control, and monitoring.

The impact of CVE-2024-32394 is substantial for organizations using affected Ruijie network devices. Successful exploitation allows attackers to execute arbitrary code remotely without authentication, potentially leading to full device compromise. This can result in unauthorized access to sensitive network traffic, disruption of network services, and the ability to pivot to other internal systems. The compromise of core network infrastructure devices can severely affect confidentiality, integrity, and availability of organizational data and services. Enterprises relying on these devices for critical connectivity or security functions face risks of data breaches, service outages, and reputational damage. Additionally, attackers could implant persistent backdoors or manipulate network traffic for espionage or sabotage. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score underscores the urgency of addressing this vulnerability.

1. Immediately restrict external network access to the management interfaces of affected Ruijie devices, ideally limiting access to trusted internal networks or VPNs. 2. Implement strict firewall rules to block unauthorized HTTP requests targeting these devices. 3. Monitor network traffic for unusual or malformed HTTP requests that could indicate exploitation attempts. 4. Conduct vulnerability scans specifically targeting Ruijie RG-RSR10-01G-T(WA)-S devices to identify affected systems. 5. Engage with Ruijie support channels to obtain and apply firmware updates or patches as soon as they become available. 6. If patches are not yet available, consider temporary mitigations such as disabling HTTP management interfaces or using alternative secure management protocols. 7. Employ network segmentation to isolate critical infrastructure devices from general user networks. 8. Maintain up-to-date backups and incident response plans to quickly recover from potential compromises. 9. Educate network administrators about this vulnerability and the importance of monitoring and restricting access to network device management interfaces.
