Correction : MINA is *not* responsible for the decoding of message. *your*
decoder is.
Keep in mind that MINA is just a dumb NIO framework that knows nothing about
the protocol you are using.

> Hi,
> We have plain text injection problem with mina 2.0.4 (It is reproducible with
> 2.0.9 as well).
> This is the problem
> The FTP client sends the commands:
> auth tls\r\nfeat
> and the feat command is executed.
> It became obvious, that the output was received encrypted. However, the
> command was sent unencrypted. In general, it is possible to inject commands
> in plain-text during the initialization of the encrypted
> channel. This can be abused for attacks against the user.
> All unencrypted commands that are send after “auth tls” must be ignored.
> Do you plan to fix this issue ?
