CVE-2025-11407 identifies an OS command injection vulnerability in the D-Link DI-7001 MINI router firmware version 24.04.18B1. The vulnerability resides in an unspecified function within the /upgrade_filter.asp file, where the 'path' parameter is improperly sanitized, allowing attackers to inject and execute arbitrary operating system commands remotely. This flaw does not require authentication or user interaction, increasing its risk profile. The attack vector is network-based, enabling remote exploitation over the internet or local networks where the device is accessible. The publicly available exploit code facilitates easier weaponization by threat actors. Successful exploitation can lead to full system compromise, enabling attackers to manipulate device configurations, intercept or redirect traffic, deploy malware, or use the device as a pivot point for further network intrusion. The CVSS 4.0 score of 5.3 reflects medium severity, considering the lack of privilege requirements but presence of partial impacts on confidentiality, integrity, and availability. No official patches or mitigations have been published yet, increasing the urgency for defensive measures. The vulnerability highlights the risks associated with embedded device firmware security, particularly in widely deployed consumer and small business networking equipment.

For European organizations, exploitation of this vulnerability could result in unauthorized control over affected D-Link DI-7001 MINI devices, potentially compromising network security and data confidentiality. Attackers could manipulate network traffic, intercept sensitive communications, or disrupt network availability by executing arbitrary commands on the device. This is particularly concerning for organizations relying on these routers in critical infrastructure, small office/home office (SOHO) environments, or remote branch networks. The ability to remotely exploit without authentication increases the threat surface, especially if devices are exposed to the internet or poorly segmented internal networks. Compromise could facilitate lateral movement within corporate networks, data exfiltration, or deployment of ransomware and other malware. The public availability of exploit code lowers the barrier for attackers, increasing the likelihood of targeted or opportunistic attacks. The medium severity rating suggests moderate but tangible risks, warranting immediate attention to prevent escalation and broader impact.

1. Immediately restrict remote access to the management interface of D-Link DI-7001 MINI devices by disabling WAN-side administration and limiting access to trusted IP addresses or VPNs. 2. Monitor network traffic for unusual patterns or commands targeting the /upgrade_filter.asp endpoint, employing intrusion detection systems with updated signatures. 3. Implement network segmentation to isolate vulnerable devices from critical systems and sensitive data repositories. 4. Regularly audit device firmware versions and configurations to identify and inventory affected units. 5. Engage with D-Link support channels to obtain official patches or firmware updates addressing this vulnerability as soon as they become available. 6. In the absence of patches, consider temporary device replacement or enhanced monitoring until remediation is possible. 7. Educate IT and security teams about this specific threat to ensure rapid detection and response. 8. Employ network-level controls such as web application firewalls (WAFs) or reverse proxies to filter malicious requests targeting the vulnerable parameter.
