Technical details

A classic buffer overflow (CWE-120) exists in the D-Link DI-8003 router running firmware version 16.07.26A1. The vulnerability is located within the /yyxz_dlink.asp endpoint, where the application fails to properly validate the length of input parameters before copying them into memory buffers. An unauthenticated remote attacker can exploit this by sending a specially crafted HTTP request to the affected endpoint. Successful exploitation can lead to a denial-of-service (DoS) condition, impacting the availability of the device. While the current CVSS assessment focuses on availability, buffer overflows can sometimes be leveraged for remote code execution depending on the underlying system architecture and protections.
