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 for this). *** This bug has been marked as a duplicate of 6394 ***
