原文摘录

摘自原文(1289 字符中的一小部分)
Summary: Curl allows `CR` and `LF` characters to be encoded in `login` and `password` netrc fields. This allows an attacker who can affect contents of the netrc entry to inject FTP commands by injecting CRLF to the `login` or `password`. POP3 is likely affected as well, but hasn't been tested.
原文中的代码
machine localhost
  login alice
  password "alicespassword\r\nDELE pocfile.txt"
