Technical details

A classic buffer overflow (CWE-120) exists in the D-Link DI-8300 router firmware version 16.07.26A1. The vulnerability is located within the 'ip_position_asp' function, which fails to properly validate the length of the 'ip' parameter before copying it into a fixed-size buffer. An unauthenticated attacker can exploit this over the network by sending a crafted input to the affected component. Successful exploitation results in a crash of the device's management process or the entire system, leading to a Denial of Service (DoS) condition.
