ftp-srv@2.9.2 vulnerabilities

ftp-srv is a Modern, extensible FTP Server

Affected versions of this package are vulnerable to Directory Traversal. In affected versions of the module, there is a path traversal vulnerability. Clients of FTP servers utilizing ftp-srv hosted on Windows machines can escape the FTP user's defined root folder using the expected FTP commands, such as CWD and UPDR. When windows separators exist within the path (\), path.resolve leaves the upper pointers intact, allowing the user to move beyond the root folder defined for that user.

Upgrade ftp-srv to version 4.4.0 or higher.
