What it is

TG8 Firewall exposes a directory such as /data/ over HTTP without authentication. This directory stores credential files for previously logged-in users. A remote unauthenticated attacker can enumerate and download files within the directory to obtain valid account usernames and passwords, leading to loss of confidentiality and further unauthorized access.
