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/formL2tpv3ConfigSetup interface where attackers can inject malicious commands via the tunnelid and sessionid fields. Successful exploitation grants root-level command execution.

Detection Guidance

Check for D-Link DWR-M961 devices with firmware versions before 1.1.5_C1_202607071108. Test the /boafrm/formL2tpv3ConfigSetup interface by sending crafted inputs to tunnelid and sessionid fields to observe command injection behavior.

Impact Analysis

An attacker could take full control of the affected D-Link device remotely without authentication. This allows them to execute arbitrary commands with highest privileges, potentially leading to data theft, device misuse, network compromise, or further attacks on connected systems.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating confidentiality requirements in GDPR and HIPAA. Organizations using affected devices may face compliance violations, regulatory fines, and reputational damage due to inadequate security controls.

Mitigation Strategies

Update the firmware of D-Link DWR-M961 devices to version 1.1.5_C1_202607071108 or later. Restrict network access to the vulnerable interface if possible. Monitor network traffic for suspicious activity targeting the /boafrm/formL2tpv3ConfigSetup endpoint.
