Technical details

The OAuthAccountServiceImp.transferSina() method derives account passwords from the first four digits of public Weibo user IDs and uses these predictable credentials for normal form-based login. Since Weibo user IDs are public information, attackers can enumerate and compromise any linked account over the network without authentication. A fix exists in versions after 5.0.
