    My interpretation is that they used a) as b), which should be fine if the salt was actually salty. I think they did:

      default_password = crypt(username+salt)

    That would be fine if they used real salt (random), but instead they used Mrs. Dash salt substitute.

    It looks from the video that the password is simply the username concatenated with a global string, "123456".

    That's not salt. That's not what the word means. A salt is data that is not part of the password but is combined with the password when hashed. The client side never sees salt.

    So all these discussions of salt are not at all relevant.

    This is fundamentally a case of hard-coded credentials [mitre.org], which is more stupid than a non-random salt. (Also, really, transmitting credentials over HTTP?)

The solution of this problem is trivial and is left as an exercise for the reader.
