# Neutrino 0.8.4 Atomic Edition Perl exploit
#
# discovered & written by Ams
# ax330d@gmail.com
#
# DESCRIPTION:
# First exploit destroys "/data/sess.php" file (simply strips tags),
# then we are able to bypass authorization and using admin privelegies
# our exploit uploads basic shell to "/data/pages/shell_name" and deletes "/data/sess.php".
# Admin will not see that "/data/sess.php" is deleted (it will be restored back in new auth).
#
# USAGE:
# Run exploit :perl expl.pl http://www.site.com
#
# NEEDED:
# regardless php.ini settings...
#
# GREETZ :P
# Goes to... SLV, to he ( he knows who =)) and
# others whom do i know =)
