basic-ftp is an FTP client for Node.js. Prior to 5.2.1, basic-ftp allows FTP command injection via CRLF sequences (\r\n) in file path parameters passed to high-level path APIs such as cd(), remove(), rename(), uploadFrom(), downloadTo(), list(), and removeDir(). The library's protectWhitespace() helper only handles leading spaces and returns other paths unchanged, while FtpContext.send() writes the resulting command string directly to the control socket with \r\n appended. This lets attacker-controlled path strings split one intended FTP command into multiple commands. This vulnerability is fixed in 5.2.1.
A flaw was found in basic-ftp, an FTP client for Node.js. A remote attacker can exploit this vulnerability by injecting Carriage Return Line Feed (CRLF) sequences into file path parameters used by high-level APIs. This allows the attacker to split a single intended FTP command into multiple commands. Such command injection can lead to the execution of arbitrary commands, potentially compromising the integrity and availability of data or the system.
