Description
The LDAP authentication method in LdapLoginModule in Hazelcast IMDG Enterprise 4.x before 4.0.3, and Jet Enterprise 4.x through 4.2, doesn't verify properly the password in some system-user-dn scenarios. As a result, users (clients/members) can be authenticated even if they provide invalid passwords.
Affected configurations
• hazelcast hazelcast (>= 4.0 < 4.0.3)
• hazelcast jet (>= 4.0 <= 4.2)
