MediaWiki before 1.27.4, 1.28.x before 1.28.3, and 1.29.x before 1.29.2,
when a private wiki is configured, provides different error messages for
failed login attempts depending on whether the username exists, which
allows remote attackers to enumerate account names and conduct brute-force
attacks via a series of requests.
