An issue was discovered in MailStore Server (and Service Provider Edition) 9.x through 11.x before 11.2.2. When the directory service (for synchronizing and authenticating users) is set to Generic LDAP, an attacker is able to login as an existing user with an arbitrary password on the second login attempt.
Weakness
