CVE-2025-10107 is a command injection vulnerability identified in the TRENDnet TEW-831DR router, specifically version 1.0 (601.130.1.1410). The vulnerability resides in an unspecified function within the /boafrm/formSysCmd file, where the sysHost argument is improperly sanitized, allowing an attacker to inject arbitrary commands. This flaw can be exploited remotely without user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:H). The vulnerability allows an attacker with high privileges (PR:H) to execute system-level commands, potentially leading to unauthorized control over the device. Although the CVSS score is rated medium at 5.1, the impact on confidentiality, integrity, and availability is low to limited, given the requirement for high privileges and the lack of user interaction. The vendor TRENDnet was contacted but has not responded or provided a patch, and no known exploits are currently observed in the wild. The vulnerability disclosure is public, which increases the risk of exploitation by attackers who can gain or already have elevated access to the device. The TEW-831DR is a consumer-grade wireless router, commonly used in small office and home environments, which may be deployed in European organizations with less stringent network security controls. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls to mitigate potential exploitation.

For European organizations, the impact of this vulnerability depends largely on the deployment context of the TRENDnet TEW-831DR routers. In environments where these devices are used as primary network gateways or in segmented network zones, successful exploitation could allow attackers to execute arbitrary commands on the router, potentially leading to network disruption, interception of traffic, or pivoting to internal systems. Although exploitation requires high privileges, if an attacker gains such access through other means (e.g., weak credentials, other vulnerabilities), this command injection could be leveraged to escalate control and compromise network integrity. The impact on confidentiality could include exposure of network configuration and traffic data, while integrity and availability could be affected by malicious command execution causing device malfunction or denial of service. European organizations with remote management enabled on these devices are at higher risk. The absence of a patch and vendor support complicates remediation, increasing the threat to organizations relying on these routers, especially in sectors with critical infrastructure or sensitive data.

Given the lack of an official patch from TRENDnet, European organizations should take immediate practical steps: 1) Disable remote management interfaces on the TEW-831DR routers to prevent external exploitation. 2) Restrict network access to the router's management interface to trusted internal IP addresses only. 3) Change default or weak administrative credentials to strong, unique passwords to reduce the risk of privilege escalation. 4) Monitor network traffic and router logs for unusual command execution or access patterns indicative of exploitation attempts. 5) Where possible, replace the affected TEW-831DR devices with alternative routers from vendors with active security support and patching. 6) Implement network segmentation to isolate vulnerable devices from critical systems. 7) Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection attempts targeting the /boafrm/formSysCmd endpoint. 8) Educate IT staff about the vulnerability and ensure incident response plans include steps for handling potential exploitation. These measures go beyond generic advice by focusing on compensating controls tailored to the specific device and vulnerability context.
