CVE-2023-46541

Unspecified impact via formIpv6Setup stack overflow

Published Oct 25, 2023 · Updated Sep 11, 2024

A stack overflow in formIpv6Setup in TOTOLINK X2000R Firmware 1.0.0-B20230221.0948.web allows remote attackers to cause unspecified impact. The handler writes beyond a stack buffer, but public materials do not identify the crafted parameter or the specific unchecked operation. Exploitation requires network adjacency but no authentication or user interaction; published metrics encompass confidentiality, integrity, and availability loss.
