Name of the Vulnerable Software and Affected Versions TG8 Firewall (affected versions not specified)

Description The TG8 Firewall exposes a directory, such as /data/, over HTTP without authentication. This directory contains credential files for previously logged-in users. A remote, unauthenticated attacker can enumerate and download files within the directory, potentially obtaining valid account usernames and passwords. This can lead to a loss of confidentiality and further unauthorized access. The vulnerable directory is accessible via the ''/data/'' API endpoint. The credentials stored within the directory are accessible through the file variable.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
