AI Analysis
Technical Summary
CVE-2025-44860 is a command injection vulnerability identified in the TOTOLINK CA300-POE router firmware version V6.2c.884_B20180522. The vulnerability exists within the msg_process function, specifically exploitable via the Port parameter. Command injection vulnerabilities occur when untrusted input is improperly sanitized and passed to a system shell or command interpreter, allowing an attacker to execute arbitrary commands on the affected device. In this case, an attacker can craft a malicious request targeting the Port parameter to inject and execute commands remotely without requiring authentication or user interaction. The CVSS 3.1 base score is 6.5, indicating a medium severity level, with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N. This means the vulnerability is remotely exploitable over the network with low attack complexity, no privileges or user interaction needed, and impacts confidentiality and integrity to a limited extent but does not affect availability. The weakness is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command ('Command Injection')). No patches or known exploits in the wild have been reported as of the publication date (May 1, 2025). TOTOLINK CA300-POE is a Power over Ethernet (PoE) router device commonly used in small to medium business and possibly some enterprise environments for network connectivity and power delivery over Ethernet cables. The vulnerability allows attackers to execute arbitrary commands, potentially leading to unauthorized access, data leakage, or further network compromise depending on the attacker's objectives and network segmentation.
Potential Impact
For European organizations, exploitation of this vulnerability could lead to unauthorized command execution on network infrastructure devices, potentially compromising network integrity and confidentiality. Although availability is not directly impacted, attackers could leverage this foothold to pivot within internal networks, escalate privileges, or exfiltrate sensitive information. Small and medium enterprises (SMEs) using TOTOLINK CA300-POE devices in their network infrastructure are at particular risk, especially if these devices are exposed to untrusted networks or lack proper segmentation. The limited impact on availability reduces the likelihood of immediate denial-of-service conditions, but the integrity and confidentiality risks remain significant. Given the low complexity and no requirement for authentication, attackers can exploit this vulnerability remotely and stealthily, increasing the threat level. European organizations in sectors such as telecommunications, manufacturing, and critical infrastructure that rely on PoE routers for network connectivity could face targeted attacks aiming to disrupt operations or steal intellectual property. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation, especially as proof-of-concept code or exploit tools may emerge.
Mitigation Recommendations
1. Network Segmentation: Isolate TOTOLINK CA300-POE devices from untrusted networks and restrict management interfaces to trusted administrative networks only. 2. Access Control: Implement strict firewall rules to limit inbound traffic to the affected devices, especially blocking unsolicited access to management ports from external networks. 3. Monitoring and Logging: Enable detailed logging on the devices and network perimeter to detect anomalous requests targeting the Port parameter or unusual command execution patterns. 4. Firmware Updates: Although no patches are currently available, maintain close communication with TOTOLINK for firmware updates addressing this vulnerability and apply them promptly once released. 5. Intrusion Detection/Prevention: Deploy network-based IDS/IPS solutions with signatures or heuristics capable of detecting command injection attempts targeting the msg_process function or suspicious payloads in Port parameter requests. 6. Device Replacement or Hardening: For critical environments, consider replacing vulnerable devices with alternatives from vendors with active security support or applying configuration hardening to minimize attack surface, such as disabling unnecessary services or interfaces. 7. Incident Response Preparedness: Prepare incident response plans that include steps to isolate affected devices and conduct forensic analysis if exploitation is suspected. 8. Vendor Engagement: Engage with TOTOLINK support channels to request security advisories and timelines for patches, and report any suspicious activity related to this vulnerability.
