SnakeYAML实现Gadget探测
思路来源
今天在学习SnakeYAML的反序列化的时候，想到⼀个新的探测payload，⽹上之前有⼀个SPI
那个链⼦可以有通过URLClassloader检测
这个的话主要是因为SnakeYAML在解析带键值对的集合的时候会对键调⽤hashCode⽅法因此
会触发DNS解析，
因此通过构造URL对象后⾯简单加个: 1让他成为⼀个mapping ，不过会触发多次

Lightweight Directory Access Protocol（LDAP），轻量级目录访问协议，基于 X.500 标准。
那么好，X.500 标准是什么？
X.500 基本上是用来查询有关人员的信息（如邮政地址、电话号码、电子邮件地址等）
的一种服务。可以有：所在机构的部门名称以及国家名称。X.500 目录服务是一种用于开发
一个单位（或组织）内部人员电子目录的标准方法，这个目录可以成为全球目录的一部分，
世界上的任何人都可以访问因特网查询到该目录。这个目录有时称全球用户信息数据库目

需要搭建一个域环境，直接把安装adaudit的机器提升为域控就行。

这个洞用了两个点串起来成了一个rce，分别是xxe和一个readObject的点。

readObject是steventseeley挖掘的Cewolf反序列化，ADAudit仍然有这个servlet，并且init参数为

近年来，在党和国家的高度重视下，网络安全行业发展迅猛，吸引了大批年轻学子和有志青年
投身其中。2015 年，“网络空间安全”正式成为“工学”门类下的一级学科，与此同时，不论是在
高校、还是企事业单位中，CTF 等类型的信息安全竞赛也开始蓬勃发展，通过竞赛涌现出了一大批
高手、能手。但是竞赛中各个模块间的发展程度却参差不齐。相对而言，Web、Misc 等模块发展较
快，参与的选手也较多；二进制安全相关模块，如 Reverse（逆向）、Mobile（此处指移动安全）等
模块的选手相对就少些，而其中的 Pwn 模块，则参赛选手最少。究其原因，主要是因为相对其他模

金和OA C6代码审计
SQL注入
金和版本C6V3.0的n day，年前同事透露了金和OA这个n day，我眼疾手快截了图下来并记了路径。
由于当时还在实习太菜了，未学习C#的代码审计，因此没有深究漏洞成因。这几天整理去年的材料时
发现手上正好有新版的金和OA备份文件，就简单来审计利用链。
