Executive Summary

This vulnerability is a command injection flaw in D-Link DWR-M961 devices running firmware before version 1.1.5_C1_202607071108. It allows a remote attacker to execute arbitrary commands with root privileges by injecting malicious input into the ussdValue and selectMenuValue fields of the /boafrm/formUSSDSetup interface.

Detection Guidance

To detect this vulnerability, scan your network for D-Link DWR-M961 devices with firmware versions before 1.1.5_C1_202607071108. Check the /boafrm/formUSSDSetup interface for exposed endpoints. Use network scanning tools like Nmap to identify vulnerable devices by querying the interface.

Impact Analysis

An attacker could take full control of the affected device, steal sensitive data, install malware, or use it as a pivot point to attack other systems on the network. This could lead to unauthorized access, data breaches, or disruption of services.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized access to sensitive data. GDPR requires protection of personal data, while HIPAA mandates safeguards for protected health information. Exploitation could result in data breaches, triggering legal penalties and reputational damage.

Mitigation Strategies

Immediately update the firmware of all D-Link DWR-M961 devices to version 1.1.5_C1_202607071108 or later. If an update is not available, isolate the affected devices from the network to prevent remote exploitation. Disable unnecessary network services on the device.
