Spring框架中文件目录遍历漏洞 Directory traversal in Spring framework

官方给出的描述是Spring框架中报告了一个与静态资源处理相关的目录遍历漏洞。某些URL在使用前未正确加密，使得攻击者能够获取文件系统上的任何文件，这些文件也可用于运行SpringWeb应用程序的进程。

受影响的版本:
Spring Framework 3.0.4 to 3.2.11
Spring Framework 4.0.0 to 4.0.7
Spring Framework 4.1.0 to 4.1.1
其他不受支持的版本也可能受到影响

影响：
攻击者可以访问存储在静态资源位置之外的文件。

解决方案：
受影响的Spring版本的用户应升级到最新版本：
Users of 3.2.x should upgrade to 3.2.12 or later
Users of 4.0.x should upgrade to 4.0.8 or later
Users of 4.1.x should upgrade to 4.1.2 or later

问题：
我的spring版本升级到5.0.2之后，在低版本的扫描工具中并没有扫出问题，问题解决，但是用高版本的扫描工具依然存在这个问题，这个时候需要将spring版本再升级到最新版本，这里我使用的5.2.5：

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<springversion>5.2.5.RELEASE</springversion>
</properties>

这个时候你的spring配置文件中配置了AnnotationMethodHandlerAdapter就会报错，因为新版本已经不再支持AnnotationMethodHandlerAdapter：

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonHttpMessageConverter"/>
</list>
</property>
</bean>

这个时候需要改成以下这样：

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonHttpMessageConverter"/>
</list>
</property>
</bean>

问题解决，还有一种，如果你引入了Jackson，版本太低也会报错，我使用的2.1.0：

我是把Jackson升级到2.9.9,运行成功:

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.9.9</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.9</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.9.9</version>
</dependency> 

希望有所帮助。
