## 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 '/web_list_opt.asp' endpoint and is triggered by improper length validation of the 's' parameter. An unauthenticated remote attacker can exploit this by sending a crafted HTTP request to the device. According to the CVSS metrics, the primary impact is on availability (Denial of Service), though buffer overflows can sometimes lead to remote code execution depending on the underlying architecture and memory protections.
