Executive Summary

This vulnerability is a command injection flaw in D-Link DWR-M961 devices with hardware version C1 and firmware before 1.1.5_C1_202607071108. It exists in the /boafrm/formDebugDiagnosticRun interface where a remote attacker can inject malicious commands into the host field. This leads to arbitrary command execution with root privileges on the affected device.

Detection Guidance

To detect this vulnerability, scan your network for D-Link DWR-M961 devices with hardware version C1 and firmware versions before 1.1.5_C1_202607071108. Check the firmware version via the device's web interface or by sending an HTTP request to the device's IP address. Look for the /boafrm/formDebugDiagnosticRun interface being accessible.

Impact Analysis

This vulnerability allows remote attackers to execute arbitrary commands with root privileges on your device. This could lead to full system compromise, unauthorized access, data theft, or disruption of device functionality. Attackers could install malware, modify system settings, or use the device as a pivot point for further attacks.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR and HIPAA requirements for data protection and access control. Organizations using affected D-Link devices may face compliance violations, regulatory fines, and reputational damage due to potential exposure of sensitive data.

Mitigation Strategies

Immediately update the firmware of all affected D-Link DWR-M961 devices to version 1.1.5_C1_202607071108 or later. If an update is not available, isolate the devices from the network to prevent remote exploitation. Disable access to the /boafrm/formDebugDiagnosticRun interface if possible.
