I realize this is an old report, however I just ran into this myself.

I'm using Filezilla 3.8.0 on Win 7 - when using sftp a password with more than 99 characters will not work. Filezilla will only use the first 99 characters as the password. Anything after that is instead seen as a command. for example - if I configure a password of 99 characters on the host that I want to connect to, and then fill in a >99 password, in this example 102 characters I will get 'Error:Unknown command: "8AB"' and 8AB equals the characters 100/101/102 of the password I sent.

This is the console output if I use a valid 99-char password + 3 additional characters (8AB) at the end of the password (character 100/101/102):
