# MemHT Portal <= 3.9.0 Perl exploit
#

#
# DESCRIPTION:
#	Script /inc/inc_statistics.php accepts unfiltered $_COOKIE's,
#	($_COOKIE['stats_res']) which later goes to MySQL request. So we are able to make
#	sql injection.
#	This exploit tries to create shell in /uploads/media/defined.php.
#
# NEEDED:
#	magic_quotes_gpc = off
#	MySQL should be able to write to file
#	Know full server path to portal
