Nuclei-Poc 开发 - Yaml 语法 & 匹配提取

YAML 是一种数据序列化语言，它的基本语法规则注意如下：

  • 大小写敏感
  • 使用缩进表示层级关系
  • 缩进时不允许使用 Tab 键，只允许使用空格。
  • 缩进的空格数目不重要，只要相同层级的元素左侧对齐即可

Yaml Poc 模版：

  1. 编号 id
  2. 信息 info
  3. 请求 http file tcp 等
  4. 匹配 matchers Interactsh
  5. 提取 extractors

开发流程：

  1. poc 模版套用修改

  2. poc 创建独立编号

  3. poc 填入详细信息

  4. poc 提交协议流程编写

  5. poc 结果匹配模式判断

  6. poc 结果提取模式判断
