AI description

Automated description summarized from trusted sources.

CVE-2025-50669 describes a buffer overflow vulnerability found in certain D-Link router models, specifically the DI-8003 (firmware version 16.07.26A1) and DI-8003G (firmware version 19.12.10A1). This flaw stems from the improper handling of the `wan_ping` parameter within the `/wan_ping.asp` endpoint. Exploitation of this vulnerability could allow an attacker to send specially crafted requests with an oversized `wan_ping` parameter, potentially leading to memory corruption. This could enable remote code execution or denial of service attacks on the affected D-Link devices. A patch has been made available to address this issue.

Description: A buffer overflow vulnerability exists in D-Link DI-8003 16.07.26A1 and DI-8003G 19.12.10A1 due to improper handling of the wan_ping parameter in the /wan_ping.asp endpoint.
