Apache Shiro RememberMe 反序列化（Shiro550）

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。

影响组件

Apache Shiro <= 1.2.4

实际漏洞影响范围

如果shiro的rememberMe功能的AES密钥被泄露, 就会导致反序列化漏洞，无论Shiro是什么版本。

目前网上收集到的密钥

漏洞复现

环境搭建：推荐docker

简单检测，抓包重放后，如果显示rememberMe=deleteMe，说明有可利用性

因为该漏洞没有回显, 所以我们需要先确认漏洞是否存在

这里用DNS解析记录来做判断, 在http://www.dnslog.cn/上获取子域

VPS启动一个nc -lvp 666

反弹shell

成功

Apache Shiro Padding Oracle Attack (Shiro-721)

Apache Shiro 是企业常见的 Java安全框架, 由于Shiro使用AES-CBC模式进行加解密处理, 所以存在Padding Oracle Attack漏洞, 已经登录的攻击者同样可以进行反序列化操作

影响组件

Apache Shiro < 1.4.2

Apache Shiro 1.2.5, 1.2.6, 1.3.0, 1.3.1, 1.3.2, 1.4.0-RC2, 1.4.0, 1.4.1

漏洞复现

shiro 环境war包 https://github.com/jas502n/SHIRO-721

搭建环境 tomcat7 + shiro 1.4.1

该漏洞需要登录后获取到合法的Cookie: rememberMe=XXX后才可以进行利用

看起来不是很好利用但实际上有一些网站是开放注册的

而且这个洞不需要知道服务端密钥，因为该漏洞需是爆破Cookie

访问shiro登录页面，并登陆

登陆后，访问一个业务，抓包

按照要求填入 rememberMe Cookie

图形化工具失败，不知道怎么回事，利用原始的方法

得到padding oracle attack后的cookie
