vsftpd through 3.0.5 contains an authentication bypass vulnerability in ssl_data_accept() that allows unauthenticated attackers to hijack FTPS data connections by resuming their own TLS session ticket. Attackers sharing the victim's source IP can obtain a ticket via AUTH TLS, then connect to the victim's PASV port to steal downloads or inject upload data.
