Technical details

A classic buffer overflow (CWE-120) exists in the D-Link DI-8003 firmware version 16.07.26A1. The vulnerability is located in the qos.asp endpoint, which fails to properly validate the length of the 'wans' parameter before copying it into a fixed-size buffer. An unauthenticated attacker can exploit this over the network to trigger a crash, leading to a denial-of-service (DoS) state. As the DI-8003 is an End-of-Life (EOL) product, no official patches are expected; the vendor recommends retiring the affected hardware.
