Description

Jivejdon through 5.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to access Weibo-created accounts by deriving predictable credentials from public Weibo user IDs. OAuthAccountServiceImp.transferSina() sets the password to the first four digits of the Weibo ID, letting attackers log in through normal form login to read or post as victims.
