原文摘录

摘自原文(2622 字符中的一小部分)
Summary: The `file://` protocol handler in curl does not properly sanitise or block path traversal sequences (`../`). This allows a maliciously crafted `file://` URL to escape the intended directory and access arbitrary files on the filesystem with the permissions of the user running curl.
原文中的代码
    ./src/curl "file:///any/dummy/path/../../../../../../etc/passwd"
