When logged in as a sysop, one can create a user account for other users,
sending a password to the user via e-mail. In 1.8.2 and before, this password
was randomly generated; however, simply logging in with nothing in the password
field is successful.
Even after logging in, both the password and a blank entry work interchangeably,
until the user changes it via Special:Preferences (in which case, only the new
password works). Even if the user logs in with the password they received via
e-mail, another user could log in later with a blank password field.
This bug has been confirmed by me in 1.8.2 and 1.7.1; a user on IRC confirms
this on 1.6.8 (the current release for PHP4 users). This doesn't work on the
English Wikipedia because the e-mail password feature requires the sysop to
enter a password for the new user. Given the extensions and changes present on
Wikipedia, I'm not sure if a vanilla svn release would be affected or not.
That's because you specified the initial password as blank (and the
form is really crappy and makes you put in an initial password
