CVE-2025-58116 is a high-severity OS command injection vulnerability affecting the I-O DATA DEVICE, INC. WN-7D36QR and WN-7D36QR/UE devices, specifically firmware versions 1.1.3 and earlier. The vulnerability arises from improper neutralization of special elements used in operating system commands, allowing a remote authenticated attacker to execute arbitrary OS commands on the affected device. This means that an attacker who has valid credentials can craft malicious input that is not properly sanitized before being passed to the underlying OS shell, leading to command execution with the privileges of the affected process. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and requiring high privileges but no user interaction. The vulnerability does not currently have known exploits in the wild, but the potential for significant damage exists due to the ability to execute arbitrary commands remotely. The affected product is a network device (likely a router or similar network hardware), which typically has privileged access to network traffic and configurations, making exploitation particularly dangerous. Since the attacker must be authenticated, the threat is somewhat mitigated by the need for credential access, but this does not eliminate risk, especially in environments where credentials may be weak, reused, or otherwise compromised. No patches or mitigation links are currently provided, indicating that organizations using these devices should be vigilant for vendor updates or consider alternative mitigations.

For European organizations, this vulnerability poses a significant risk, especially for those relying on the WN-7D36QR devices in their network infrastructure. Successful exploitation could lead to full compromise of the device, allowing attackers to intercept, modify, or disrupt network traffic, exfiltrate sensitive data, or pivot to other internal systems. The high impact on confidentiality, integrity, and availability means critical business operations could be disrupted, sensitive information leaked, or network trust undermined. Given the requirement for authentication, insider threats or compromised credentials pose a notable risk vector. Additionally, the lack of known exploits in the wild should not lead to complacency, as attackers often develop exploits rapidly once vulnerabilities are public. European organizations in sectors such as finance, healthcare, government, and critical infrastructure, which rely heavily on secure network devices, may face increased risk. The vulnerability could also be leveraged in targeted attacks or espionage campaigns, especially given the geopolitical importance of certain European regions.

1. Immediate mitigation should include restricting administrative access to the affected devices to trusted networks and users only, employing strong, unique passwords and multi-factor authentication where possible to reduce the risk of credential compromise. 2. Network segmentation should be enforced to limit the exposure of these devices to untrusted networks or users. 3. Monitor device logs and network traffic for unusual command execution patterns or unauthorized access attempts. 4. Disable any unnecessary services or remote management features on the devices to reduce the attack surface. 5. Regularly check for firmware updates from I-O DATA DEVICE, INC. and apply patches promptly once available. 6. If patching is delayed, consider replacing affected devices with alternative hardware that does not have this vulnerability. 7. Conduct internal audits to ensure that credentials used for device access are not reused elsewhere and are rotated regularly. 8. Employ intrusion detection/prevention systems (IDS/IPS) to detect potential exploitation attempts targeting these devices. 9. Educate network administrators about the vulnerability and the importance of secure management practices for network hardware.
