Security News > 2024 > May > PoC exploit released for RCE zero-day in D-Link EXO AX4800 routers
The D-Link EXO AX4800 router is vulnerable to remote unauthenticated command execution that could lead to complete device takeovers by attackers with access to the HNAP port.
The D-Link DIR-X4860 router is a high-performance Wi-Fi 6 router capable of speeds of up to 4800 Mbps and advanced features like OFDMA, MU-MIMO, and BSS Coloring that enhance efficiency and reduce interference.
Accessing the Home Network Administration Protocol port on the D-Link DIR-X4860 router is relatively straightforward in most cases, as it's usually HTTP or HTTPS accessible through the router's remote management interface.
The attack begins with a specially crafted HNAP login request to the router's management interface, which includes a parameter named 'PrivateLogin' set to "Username" and a username of "Admin".
The vulnerable 'SetVirtualServerSettings' function processes the 'LocalIPAddress' parameter without proper sanitization, allowing the injected command to execute in the context of the router's operating system.
