# Copyright (c) 2007 Marco Ivaldi <raptor@xxxxxxxxxxxxxxx>
#
# Lotus Domino R5 and R6 WebMail, with "Generate HTML for all fields"
enabled,
# stores sensitive data from names.nsf in hidden form fields, which allows
# remote attackers to read the HTML source to obtain sensitive information
such
# as (1) the password hash in the HTTPPassword field, (2) the password
change
# date in the HTTPPasswordChangeDate field, (3) the client platform in the
# ClntPltfrm field, (4) the client machine name in the ClntMachine field,
and
# (5) the client Lotus Domino release in the ClntBld field, a different
# vulnerability than CVE-2005-2696 (CVE-2005-2428).
#
# According to testing, it's possible to dump all HTTPPassword hashes
using the
# $defaultview view instead of $users. This saves a considerable amount of
time.
#
# The code may require some changes to properly work with your
configuration.
#

#
# Usage:
# $ ./raptor_dominohash 192.168.0.202
# [...]
# Extracting the view entries...
# Done! 656 unique entries have been found.
# Now ready to dump password hashes...
