G416 LAN-Side Unathenticated Command Injection

23 novembar, 2023

Overview

 

On July 7, 2023 and July 28, 2023,  3rd party security research from TrendMicro ZDI reported the (Non-US) D-Link G416 WiFi 4G Mobile Router H/W Rev. Ax :: F/W v1.08b02 having multiple security vulnerabilities.

 

An OS command injection vulnerability has been discovered in D-Link G416, which can be exploited by unauthenticated attackers that get access to the LANside of the device to execute arbitrary code with root privileges.

 

D-Link takes the issues of network security and user privacy very seriously. We have a dedicated task force and product management team on call to address evolving security issues and implement appropriate security measures.
