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/formTracerouteDiagnosticRun interface where attackers can inject malicious commands via the host and ipVer fields. Successful exploitation grants root-level command execution.

Detection Guidance

Check for firmware versions before 1.1.5_C1_202607071108 on D-Link DWR-M961 devices with hardware version C1. Test the /boafrm/formTracerouteDiagnosticRun interface for command injection by sending crafted inputs to the host and ipVer fields.

Impact Analysis

An attacker could take full control of your D-Link DWR-M961 device remotely without authentication. This could allow them to modify settings, intercept network traffic, install malware, or use your device as a pivot point to attack other systems on your network.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR's security requirements for personal data protection and HIPAA's safeguards for protected health information. Organizations may face compliance penalties if this flaw is exploited to access sensitive data.

Mitigation Strategies

Update the firmware to version 1.1.5_C1_202607071108 or later. If immediate updates are not possible, restrict network access to the vulnerable interface or disable it entirely.
