Description
TWiki 4.0.5 and earlier, when running under Apache 1.3 using ApacheLogin with sessions and "ErrorDocument 401" redirects to a valid wiki topic, does not properly handle failed login attempts, which allows remote attackers to read arbitrary content by cancelling out of a failed authentication with a valid username and invalid password.
