Technical Analysis

CVE-2025-44845 is a command injection vulnerability identified in the TOTOLINK CA600-PoE router, specifically in firmware version V5.3c.6665_B20180820. The vulnerability exists within the NTPSyncWithHost function, which processes the hostTime parameter. An attacker can exploit this flaw by sending a specially crafted request that injects arbitrary commands into the system. This occurs because the input is not properly sanitized before being passed to a command execution context, corresponding to CWE-77 (Improper Neutralization of Special Elements used in a Command). The vulnerability has a CVSS 3.1 base score of 6.5, indicating a medium severity level. The vector metrics indicate that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N). The impact on confidentiality and integrity is low, with no direct impact on availability. No known exploits are currently reported in the wild, and no patches or vendor advisories have been published yet. The vulnerability allows an attacker to execute arbitrary commands on the device, potentially leading to unauthorized access, data leakage, or further network compromise if the device is part of a larger infrastructure. Given the device is a PoE (Power over Ethernet) router, it is likely deployed in small to medium enterprise or branch office environments, where it manages network traffic and possibly powers connected devices. The lack of authentication requirements and the network accessibility of the vulnerable function increase the risk of exploitation if the device is exposed to untrusted networks or the internet.

Potential Impact

For European organizations, exploitation of this vulnerability could lead to unauthorized command execution on TOTOLINK CA600-PoE routers, potentially compromising network integrity and confidentiality. Attackers could leverage this to intercept or manipulate network traffic, pivot to other internal systems, or disrupt network management functions. While the direct availability impact is low, the indirect consequences could include data breaches or operational disruptions, especially in organizations relying on these routers for critical connectivity or powering network devices. Small and medium enterprises, branch offices, or remote sites using this router model are particularly at risk. Additionally, if these devices are part of industrial or IoT environments, attackers might gain footholds that could affect operational technology systems. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors. However, the ease of exploitation and lack of required privileges make it a notable threat that should be addressed promptly to prevent lateral movement or escalation in targeted attacks.

Mitigation Recommendations

1. Network Segmentation: Isolate TOTOLINK CA600-PoE routers from untrusted networks and restrict management interfaces to trusted administrative subnets only. 2. Access Control: Implement strict firewall rules to limit inbound traffic to the router’s management ports, ideally allowing access only from known IP addresses. 3. Monitoring and Logging: Enable detailed logging on the router and network perimeter devices to detect anomalous requests targeting the NTPSyncWithHost function or unusual command execution patterns. 4. Firmware Updates: Although no patches are currently available, maintain close contact with TOTOLINK for firmware updates or advisories and apply them immediately upon release. 5. Device Inventory and Exposure Assessment: Identify all TOTOLINK CA600-PoE devices in the environment and assess their exposure to external networks. Remove or replace devices that cannot be adequately protected. 6. Intrusion Detection: Deploy network intrusion detection systems (NIDS) with signatures or heuristics to detect command injection attempts targeting this vulnerability. 7. Disable Unnecessary Services: If possible, disable or restrict the NTPSyncWithHost functionality or related services that process external input until a patch is available. 8. Incident Response Preparedness: Prepare response plans for potential exploitation scenarios, including isolating affected devices and forensic analysis procedures.
