Technical details

A stack-based buffer overflow (CWE-121) exists in the D-Link DI-8003 router running firmware version 16.07.26A1. The vulnerability is located within the /usb_paswd.asp endpoint and is triggered by improper validation of the 'name' parameter. A remote, unauthenticated attacker can exploit this over the network by sending a specially crafted request. Successful exploitation results in a denial-of-service (DoS) condition, impacting the availability of the device. No patch is available as the product is End-of-Life (EoL).
