Executive Summary

This is a command injection vulnerability in D-Link DWR-M961 devices with hardware version C1 and firmware before 1.1.5_C1_202607071108. It exists in the /boafrm/formLtefotaUpgradeQuectel interface where attackers can inject malicious commands via the fota_url field. Exploitation leads to root-level command execution.

Detection Guidance

Check if your D-Link DWR-M961 device has firmware version before 1.1.5_C1_202607071108. Verify if the vulnerable interface /boafrm/formLtefotaUpgradeQuectel is accessible. Use network scanning tools to detect open ports and services on the device.

Impact Analysis

A remote attacker could take full control of the device with root privileges. This could allow them to execute arbitrary commands, install malware, steal data, or disrupt device functionality. Unpatched devices are at high risk of compromise.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary commands with root privileges on affected D-Link DWR-M961 devices. Such unauthorized access could lead to data breaches, unauthorized data access, or modification, which may violate compliance requirements under standards like GDPR (data protection) and HIPAA (healthcare data security).

Mitigation Strategies

Update the device firmware to version 1.1.5_C1_202607071108 or later immediately. Disable remote access to the vulnerable interface if not required. Isolate the device from critical network segments until patched.
