YaTFTPSvr TFTP Server Directory Traversal Vulnerability

YaTFTPSvr TFTP Server is prone to a directory-traversal vulnerability because it fails to sufficiently sanitize user-supplied input.

A remote attacker could exploit this vulnerability using directory-traversal strings (such as '../') to upload and download arbitrary files outside of the TFTP server root directory. This could help the attacker launch further attacks.

YaTFTPSvr 1.0.1.200 is vulnerable; other versions may also be affected.
