DigPHP - 'dig.php' Script Remote File Disclosure

source: https://www.securityfocus.com/bid/54207/info

DigPHP is prone to a remote file-disclosure vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability to view local files in the context of the web server process, which may aid in further attacks.
