Terracotta - 'index.php' Local File Inclusion
source: https://www.securityfocus.com/bid/28550/info
Terracotta is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.
An attacker can exploit this vulnerability using directory-traversal strings to view local files in the context of the webserver process. This may aid in further attacks.
