Technical details

A classic buffer overflow (CWE-120) exists in the D-Link DI-8003 router, specifically within firmware version 16.07.26A1. The vulnerability is located in the /wan_line_detection.asp endpoint due to improper validation of the 'iface' parameter. An unauthenticated attacker can exploit this over the network by sending a request with an oversized string to the affected parameter, leading to memory corruption. According to the CVSS metrics, the primary impact is on system availability (Denial of Service), though buffer overflows can sometimes lead to remote code execution. Users should check the D-Link security bulletin for firmware updates as this version is confirmed vulnerable.
