CVE-2025-11408 is a buffer overflow vulnerability identified in the D-Link DI-7001 MINI router firmware version 24.04.18B1. The vulnerability arises from improper input validation in an unspecified function within the /dbsrv.asp web interface file, specifically related to the handling of the 'str' argument. This flaw allows an attacker to remotely send crafted requests that overflow the buffer, potentially overwriting memory and enabling arbitrary code execution. The attack vector is network-based, requiring no authentication or user interaction, which significantly lowers the barrier for exploitation. The CVSS v4.0 score of 8.7 reflects the high impact on confidentiality, integrity, and availability, as successful exploitation could lead to full device compromise. Although no confirmed exploits are currently active in the wild, the public disclosure of exploit details increases the likelihood of future attacks. The vulnerability affects the firmware version 24.04.18B1 specifically, and no patches have been linked yet, indicating that affected users must be vigilant. The D-Link DI-7001 MINI is typically used in small office or home office environments, but its compromise could serve as a foothold for attackers targeting broader network infrastructure. The lack of scope change and no requirement for privileges or user interaction make this vulnerability particularly dangerous for exposed devices. Organizations should prioritize identifying affected devices and implementing network-level protections while awaiting official patches.

For European organizations, this vulnerability poses a significant risk due to the potential for remote code execution on network devices that often serve as gateways or critical infrastructure components. Compromise of the D-Link DI-7001 MINI routers could lead to interception or manipulation of network traffic, unauthorized access to internal systems, and disruption of network availability. Given the device’s role in small office/home office environments, attacks could facilitate lateral movement into corporate networks or be used as part of larger botnet operations. The confidentiality of sensitive data traversing these routers could be jeopardized, and integrity of communications undermined. Availability impacts could manifest as denial of service or device bricking, disrupting business operations. European organizations with limited network segmentation or exposed management interfaces are particularly vulnerable. The public disclosure of exploit details increases the urgency for mitigation to prevent exploitation attempts. The absence of known exploits in the wild currently offers a window for proactive defense, but this may close rapidly.

1. Immediately inventory all D-Link DI-7001 MINI devices running firmware version 24.04.18B1 within the organization. 2. Restrict remote access to router management interfaces by implementing network segmentation and firewall rules limiting access to trusted IP addresses only. 3. Disable any unnecessary services or web interfaces on the affected devices to reduce the attack surface. 4. Monitor network traffic for unusual patterns or signs of exploitation attempts targeting /dbsrv.asp or related endpoints. 5. Apply vendor-provided patches or firmware updates as soon as they become available; maintain contact with D-Link support channels for updates. 6. Consider replacing affected devices with models that have no known vulnerabilities if patches are delayed. 7. Implement intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics capable of detecting buffer overflow attempts against these routers. 8. Educate IT staff about this vulnerability and ensure incident response plans include steps for compromised network devices. 9. Regularly back up router configurations to enable rapid recovery if devices are compromised. 10. Engage with cybersecurity threat intelligence feeds to stay informed about emerging exploits related to this CVE.
