When to Use

When to Use

  • 参数、文件名、下载接口或导入流程会影响文件路径
  • 目标支持上传、预览、转码、解压、分享、下载或代理文件访问
  • 你需要判断当前更偏向路径穿越、LFI,还是上传验证与处理链问题
  • Parameters, file names, download endpoints or import processes affect the file path
  • The target supports upload, preview, transcoding, decompression, sharing, download or proxy file access
  • You need to determine whether the current problem is more inclined to path traversal, LFI, or upload verification and processing chain issues

  • Path Traversal LFI: 路径穿越、文件读取、wrapper、包含链
  • Upload Insecure Files: 上传校验、存储路径、处理链、覆盖、预览与分享边界
  • Path Traversal LFI: path traversal, file reading, wrapper, inclusion chain
  • Upload Insecure Files: upload verification, storage path, processing chain, overwriting, preview and sharing boundaries

Recommended Flow

Recommended Flow

  1. 先看入口是路径参数、下载接口还是上传流程
  2. 再看问题出现在 accept、store、process、serve 哪一段
  3. 小样本路径链和上传绕过样本已经并入主专题 skill,不再单独走 payload 入口
  1. First check whether the entry is a path parameter, download endpoint or upload process
  2. Then check which segment the problem occurs in: accept, store, process, or serve
  3. Small sample path chains and upload bypass samples have been merged into the main topic skill, and no longer use separate payload entries
