Spring Boot Actuator 1.x 版本默认内置路由的起始路径为 / ，2.x 版本则统一以 /actuator 为起始路径
Spring Boot Actuator 默认的内置路由名字，如 /env 有时候也会被程序员修改，比如修改成 /appenv
一般来讲，暴露出 spring boot 应用的相关接口和传参信息并不能算是漏洞，但是以 “默认安全” 来讲，不暴露出这些信息更加安全。
对于攻击者来讲，一般会仔细审计暴露出的接口以增加对业务系统的了解，并会同时检查应用系统是否存在未授权访问、越权等其他业务类型漏洞。
URLDNS 是ysoserial中⼀个利⽤链的名字，但准确来说，这个其实不能称作“利⽤链”。因为其参数不是⼀个可以“利⽤”的命令，⽽仅为⼀个URL，其能触发的结果也不是命令执⾏，⽽是⼀次DNS请求。
虽然这个“利⽤链”实际上是不能“利⽤”的，但因为其如下的优点，⾮常适合我们在检测反序列化漏洞时使⽤
序列化是将Java对象转换成字节流的过程。而反序列化是将字节流转换成Java对象的过程， java序列化的数据一般会以标记(ac ed 00 05)开头，base64编码的特征为rO0AB，
JAVA常见的序列化和反序列化的方法有JAVA 原生序列化和JSON 类（fastjson、jackson）序列化等。
要了解XXE漏洞，那么先得了解一下有关XML的基础知识。
XML是一种非常流行的标记语言，在1990年代后期首次标准化，并被无数的软件项目所采用。它用于配置文件，文档格式（如OOXML，ODF，PDF，RSS，…），图像格式（SVG，EXIF标题）和网络协议（WebDAV，CalDAV，XMLRPC，SOAP，XMPP，SAML， XACML，…）
没有对用户的输入进行处理(过滤,黑名单,SQL预编译),直接将输入拼接到了sql语句中,
导致执行了用户构造的恶意SQL语句
SQL注入的语法与使用的数据库相关,与语言无关
java database connection
java提供的数据库驱动库,用于进行数据库连接,执行SQL语句
JDBC有两个方法执行SQL语句，分别是PrepareStatement和Statement。
在打tryhackme的New-York-Flankees房间的时候遇见了这个攻击方式,没见过,学习一下
在分组密码加密领域，数据一次加密一个块，不同算法的块长度各不相同。
当要加密的数据长度不是块长度的倍数时，就需要填充。
高级加密标准 (AES)
数据加密标准 (DES)
三重数据加密标准 (3DES)
Blowfish
Twofish
如前所述，分组密码采用固定大小的块，当明文不是块大小的倍数时需要填充。存在多种填充技术，但在本次攻击中，我们的重点是 PKCS#7。

trainerjeff 接下来得看 mysql 了 hydra 好慢 换了 ncrack 试试
sudo ncrack -T5 -v -u trainerjeff -P /usr/share/wordlists/rockyou.txt mysql://192.168.10.8
sudo medusa -h 192.168.10.8 -u trainerjeff -P /usr/share/wordlists/rockyou.txt -M mysql
sudo hydra -l trainerjeff -P /usr/share/wordlists/rockyou.txt 192.168.10.8 mysql
没出来, 吐了, 每分钟八次. 太慢了. 看 wp 算了
假装枚举出来了
sudo mysql -h 192.168.10.8 -u trainerjeff -psoccer1
