Unauthenticated WebGUI access

Published Aug 31, 2023 · Updated Feb 13, 2025

Broadcom identifies the WebGUI as the affected component but does not disclose the request path, credential check, or authorization decision that fails. The flaw is remotely reachable without credentials or user interaction, but Broadcom does not specify which data or administrative actions become accessible.
