Executive Summary

This vulnerability is a command injection weakness in the D-Link DWR-M920 device up to version 1.1.50. It occurs in the function sub_4155B4 within the file /boafrm/formLtefotaUpgradeFibocom. By manipulating the argument 'fota_url', an attacker can inject and execute arbitrary commands remotely on the device.

Impact Analysis

The vulnerability allows remote attackers to execute arbitrary commands on the affected device, potentially leading to unauthorized control, data compromise, disruption of service, or further exploitation within the network.

Detection Guidance

Detection can focus on monitoring HTTP requests to the vulnerable endpoint `/boafrm/formLtefotaUpgradeFibocom` with suspicious or unusual `fota_url` parameter values that may indicate command injection attempts. Network intrusion detection systems (NIDS) or web application firewalls (WAF) can be configured to alert on requests containing shell metacharacters or command injection patterns targeting this URL. Specific commands to detect exploitation attempts are not provided in the resources. [1, 3]

Mitigation Strategies

Immediate mitigation steps include discontinuing use of the affected D-Link DWR-M920 firmware versions up to 1.1.50, as no official patches or countermeasures are available. Replacement of the affected product is suggested to avoid exploitation. Additionally, restricting network access to the vulnerable device, especially blocking external access to the `/boafrm/formLtefotaUpgradeFibocom` endpoint, and monitoring for suspicious activity can help reduce risk.
