Summary

This security flaw in the web management portal of D-Link DIR-1935 routers enables network-adjacent attackers to execute arbitrary code. The vulnerability arises from how the router processes requests related to virtual server settings. Specifically, it improperly validates user-supplied strings when handling SetVirtualServerSettings, allowing attackers to bypass authentication and execute commands as root. This poses a significant risk as it can lead to unauthorized access and control of the affected devices.
