Technical Analysis

CVE-2025-41427 is a high-severity OS command injection vulnerability affecting ELECOM CO.,LTD.'s WRC-X3000GS series routers, including models WRC-X3000GS, WRC-X3000GSA, and WRC-X3000GSN, specifically in firmware versions v1.0.34 and earlier. The vulnerability exists due to improper neutralization of special elements in the Connection Diagnostics page, which allows a remote attacker with authenticated access to send specially crafted requests that can execute arbitrary operating system commands on the device. This type of vulnerability arises when user-supplied input is incorporated into OS commands without adequate sanitization or escaping, enabling injection of malicious commands. The CVSS 3.0 base score of 8.8 reflects the critical impact on confidentiality, integrity, and availability, with low attack complexity, requiring only privileges of an authenticated user and no user interaction. Exploitation could lead to full compromise of the router, allowing attackers to manipulate network traffic, intercept sensitive data, disrupt network services, or pivot to internal networks. Although no known exploits are currently reported in the wild, the vulnerability’s characteristics make it a significant risk, especially in environments where these routers are deployed and accessible to authenticated users, such as enterprise or organizational networks. The lack of available patches at the time of publication increases the urgency for mitigation and monitoring.

Potential Impact

For European organizations, exploitation of this vulnerability could have severe consequences. The WRC-X3000GS series routers are used in both consumer and small-to-medium business environments, and potentially in some enterprise settings. Successful exploitation could allow attackers to gain control over network infrastructure, leading to interception or manipulation of sensitive communications, disruption of internet connectivity, and potential lateral movement within corporate networks. This could compromise confidentiality of personal and corporate data, integrity of network operations, and availability of critical services. Given the router’s role as a gateway device, attackers could establish persistent footholds or launch further attacks against connected systems. The requirement for authentication limits exposure but does not eliminate risk, as credential theft or insider threats could facilitate exploitation. The impact is heightened in sectors with stringent data protection requirements under GDPR and critical infrastructure entities, where network compromise could lead to regulatory penalties and operational disruptions.

Mitigation Recommendations

1. Immediate mitigation should focus on restricting access to the router’s management interface, ensuring it is not exposed to untrusted networks or the internet. 2. Enforce strong authentication mechanisms and regularly update credentials to reduce risk of unauthorized access. 3. Monitor router logs and network traffic for unusual activities indicative of exploitation attempts, such as unexpected command execution or configuration changes. 4. Segment networks to limit the impact of a compromised router, isolating critical systems from devices with known vulnerabilities. 5. Engage with ELECOM CO.,LTD. for firmware updates or patches addressing this vulnerability; if unavailable, consider temporary replacement or additional protective controls such as web application firewalls or intrusion prevention systems that can detect and block command injection patterns. 6. Educate network administrators on the risks of OS command injection and the importance of secure configuration and monitoring. 7. Implement multi-factor authentication for router access where supported to further reduce risk of credential compromise.
