# 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} [-?] [-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.
