## 0.For Me

仅仅只是想写给自己看

一个记录我Java安全学习过程的仓库，本仓库不是真正意义上的教学仓库(rep中的内容都是我在平时的一些笔记没有很强逻辑性，内容水平自然也是参差不齐，可能有些对我来说很简单的便忽略不计对其他人来说却是难点，因此作为一个学习目录的话可能会好很多)，单纯这是笔者简单记一些笔记，顺便见证自己从0到0.1的过程吧，另外后面如果看到一些好的东西在学习完之后也会贴上链接，少了很多介绍性的东西，以后等厉害了再慢慢补充吧.当然如果感觉还不错的话，师傅们记得给个 Star 呀 ~

## 2.反序列化

很早前学了，后面补上，更多是说一点关键的东西，不会很详细，好吧这里再拓展成反序列化专区好了

如果想系统学习CC链、CB链的话这部分还是推荐p牛的[Java安全漫谈](https://github.com/phith0n/JavaThings)，我只是简单写写便于自己复习而已(这部分看我下面的share并不适合新人，过了这么久看过网上很多文章还是觉得P牛写的更适合新人)

### 2.1 反序列化基础技术补充（建议先补理论再看链子）

- **官方机制与防护入口（必修）**
  - [Java Object Serialization Specification](https://docs.oracle.com/en/java/javase/22/docs/specs/serialization/index.html)（序列化协议、`readObject/writeObject`、`serialVersionUID`等基础语义）
  - [JEP 290: Filter Incoming Serialization Data](https://openjdk.org/jeps/290)（全局/上下文过滤器设计思路）
- **漏洞定义与防御基线（必修）**
  - [CWE-502: Deserialization of Untrusted Data](https://cwe.mitre.org/data/definitions/502.html)（风险定义、常见后果与缓解建议）
  - [OWASP Deserialization Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Deserialization_Cheat_Sheet.html)（工程侧防护 checklist）
- **工具与实践（建议配合靶场）**
  - [ysoserial](https://github.com/frohoff/ysoserial)（理解 gadget chain 构造与触发路径的经典工具）

### 2.2 建议学习顺序（反序列化）

1. 先读序列化规范 -> 2. 理解 `ObjectInputStream` 触发路径 -> 3. 学 URLDNS/CC 等入门链 -> 4. 学 JEP 290 与白名单过滤 -> 5. 再看特定框架（Hessian/XStream/SnakeYAML）利用。

## 3.Fastjson/Jackson专区

可以对比jackson简单学习下，这里我也会简单提一下jackson的一些利用，当然不会很详细，但是会简单列出一些触发原理，而且有些payload是共通的，这里也不以收集各个依赖下利用的payload为主

后面因为一些原因打算更系统学习，感觉在这里面直接添加有点臃肿，故开了一个新的repo来记录整个学习阶段，移步[RaspLearning](https://github.com/Y4tacker/RaspLearning)

## 7.Struts2学习专区

后面突然觉得调试的过程很无聊我也不感兴趣，更感兴趣的是关于Struts当中Ognl的攻防所以后面更偏向于这方面研究，而不再具体跟踪中间的调用过程

## 9.JDBC Attack

关于Make JDBC Attacks Brilliant Again的简单记录，当我们在 JDBC Connection URL可控的情况下，攻击者可以进行什么样的攻击？这部分可以配合[探索高版本 JDK 下 JNDI 漏洞的利用方法](https://tttang.com/archive/1405/)来进行拓展攻击

## 19.ASM与JVM学习


- [JAVA虚拟机执行模型(关注引入了栈映射帧，用于加快虚拟机中类验证过程的速度)](https://www.cnblogs.com/coding-way/p/6600647.html)
- [What is a stack map frame](https://stackoverflow.com/questions/25109942/what-is-a-stack-map-frame)
  - 这里比较有意思的是：Java 1.7引入了此选项以加速类验证。框架分为两部分：变量类型和堆栈类型。第一帧由方法类型描述。在每个GOTO / JUMP调用之后，您需要提供堆栈映射框架的更新描述。为了节省空间，可以使用SAME，APPEND等选项，也可以通过指定变量类型的FULL数组再次描述所有变量。
