Technical details

A classic buffer overflow (CWE-120) exists in the D-Link DI-8003 router firmware version 16.07.26A1. The vulnerability is located in the '/thd_member.asp' endpoint and is caused by improper validation of the 'id' parameter. An unauthenticated attacker can exploit this over the network by sending a malicious request that exceeds the expected buffer size, leading to memory corruption. According to the CVSS vector, the primary impact is on availability (Denial of Service). D-Link has classified this device as End-of-Life (EOL), meaning no official patches will be provided.
