The remote mail service allows plaintext command injection while
negotiating an encrypted communications channel.
The remote SMTP service contains a software flaw in its STARTTLS
implementation that could allow a remote, unauthenticated attacker to
inject commands during the plaintext protocol phase that will be
executed during the ciphertext protocol phase.
Successful exploitation could allow an attacker to steal a victim's
email or associated SASL (Simple Authentication and Security Layer)
