Authenticated browser data access via script injection

Published May 17, 2023 · Updated Jan 22, 2025

Cross-site scripting in ASUSTOR ADM, LooksGood, and SoundsGood allows remote authenticated users to access browser-held data. ASUSTOR has not disclosed the vulnerable parameter, endpoint, or missing output-encoding operation that permits injected script to run. A low-privileged account is required; successful exploitation exposes cookies or other sensitive browser data and can alter browser-side content.
