vsftpd through 3.0.5 require_ssl_reuse Bypass via FTPS Data Channel Hijacking
Impact
vsftpd through 3.0.5 has an authentication bypass vulnerability via FTPS data channel hijacking, allowing unauthenticated attackers with the same source IP as the victim to steal downloads or inject upload data. The attacker must share the victim's source IP and obtain a TLS session ticket. This is due to improper verification of the communication channel source.
