Descriptions

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.

El método de autenticación LDAP en LdapLoginModule en Hazelcast IMDG Enterprise versiones 4.x anteriores a 4.0.3, y Jet Enterprise versiones 4.x anteriores a 4.2, no comprueba apropiadamente la contraseña en algunos escenarios de system-user-dn. Como resultado, los usuarios (clients/members) pueden ser autenticados incluso si proporcionan contraseñas no válidas
