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 /qos_type_asp.asp endpoint and is caused by insufficient validation of the 'name' input parameter. A remote, unauthenticated attacker can exploit this by sending a long string to the affected parameter, leading to memory corruption. According to the CVSS metrics provided by CISA-ADP, the primary impact is on system availability (Denial of Service), though the device has reached End-of-Life (EoL) status, meaning no official patches are expected.
